Spring Security教學 » Spring Security+Hibernate記住我範例

Spring Security+Hibernate記住我範例

本教學介紹了使用Spring Security與Hibernate實現"記住我"認證功能。
"記住我" 是持久登入認證，應用程式會記住對談使用者的身份。基本上，在登入時當你使用"記住我"功能支援，應用程式會將一個cookie在登入成功後傳送到瀏覽器。這個 cookie 將被儲存在瀏覽器端，並繼續在一定期限(由cookie生命過期時間定義)。 下一次，當您嘗試存取該應用程式，瀏覽器將檢測到的cookie(如果仍然有效)那麼些使用者將會自動登入，無需提供如使用者ID/密碼。
Spring Security提供了兩種 「記住我」的實現：
  • 簡單基於雜湊標記的方法：它使用雜湊來保護基於cookie標記的安全性
  • 持久化標記方法：它使用一個資料庫或其他持久化儲存機制來儲存生成的標記
在這篇文章中，我們將討論關於持久化標記方法
相對於正常登入教學文章作了一些以下的修改：
1.持久化標記方法，資料庫中新增一個名為：persistent_logins 的表，可以建立使用下面的SQL： 
CREATE TABLE persistent_logins (
    username VARCHAR(64) NOT NULL,
    series VARCHAR(64) NOT NULL,
    token VARCHAR(64) NOT NULL,
    last_used TIMESTAMP NOT NULL,
    PRIMARY KEY (series)
); 

此表包含使用者名，「記住我」的最後一次活動時間(last_used時間戳)，Bcrypt內部實現安全令牌和一系列資訊。 

2.在Spring Security組態"記住我" 
package com.yiibai.springsecurity.configuration;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

	@Autowired
	@Qualifier("customUserDetailsService")
	UserDetailsService userDetailsService;
	
	@Autowired
	DataSource dataSource;
	
	@Autowired
	public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
		auth.userDetailsService(userDetailsService);
	}
	
	@Override
	protected void configure(HttpSecurity http) throws Exception {
	  http.authorizeRequests()
	  	.antMatchers("/", "/home").permitAll()
	  	.antMatchers("/admin/**").access("hasRole('ADMIN')")
	  	.antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
	  	.and().formLogin().loginPage("/login")
	  	.usernameParameter("ssoId").passwordParameter("password")
	  	.and().rememberMe().rememberMeParameter("remember-me").tokenRepository(persistentTokenRepository()).tokenValiditySeconds(86400)
	  	.and().csrf()
	  	.and().exceptionHandling().accessDeniedPage("/Access_Denied");
	}
	
	@Bean
	public PersistentTokenRepository persistentTokenRepository() {
		JdbcTokenRepositoryImpl tokenRepositoryImpl = new JdbcTokenRepositoryImpl();
		tokenRepositoryImpl.setDataSource(dataSource);
		return tokenRepositoryImpl;
	}
} 

請注意，我們可呼叫 rememberMe() 來組態記住我，在檢視中提供一個「記住我」核取方塊身份驗證的HTTP引數名稱(我們將在檢視中看到)。我們還指定要使用 tokenRepository(令牌將被儲存)，並將該令牌的時間(以秒為單位)仍然有效。要組態儲存庫時我們要注入了一個資料源。

這是所有你需要啟用"記住我"，在Spring Security基礎的應用程式中。
或者，可以使用Spring Security內建表達以及Spring security標籤在您的檢視根據特定的邏輯客製化/顯示/隱藏 "記住我"或使用安全認證。
注意：如果你不願意使用JDBC，可能在應用程式是基於Hibernate，現在你可以參考Spring MVC+Spring Security+hibernate範例，在這裡我建立了一個基於Hibernate實現PersistentTokenRepository，它被命名為 HibernateTokenRepositoryImpl。
以上安全組態以XML組態格式為： 
<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
    http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-4.0.xsd">
     
    <http auto-config="true" >
        <intercept-url pattern="/" access="permitAll" />
        <intercept-url pattern="/home" access="permitAll" />
        <intercept-url pattern="/admin**" access="hasRole('ADMIN')" />
        <intercept-url pattern="/dba**" access="hasRole('ADMIN') and hasRole('DBA')" />
        <form-login  login-page="/login" 
                     username-parameter="ssoId" 
                     password-parameter="password" 
                     authentication-failure-url="/Access_Denied" />
        <csrf/>
    </http>
 
    <authentication-manager >
        <authentication-provider user-service-ref="customUserDetailsService"/>
    </authentication-manager>
     
    <remember-me 
        remember-me-parameter="remember-me"
        remember-me-cookie="remember-me"
        token-validity-seconds="86400"
	data-source-ref="dataSource" />

    <beans:bean id="customUserDetailsService" class="com.yiibai.springsecurity.service.CustomUserDetailsService" />
    
</beans:beans>
完整的程式碼範例如下所示。

完整的範例

需要使用到以下技術：
  • Spring 4.1.6.RELEASE
  • Spring Security 4.0.1.RELEASE
  • Hibernate 4.3.6.Final
  • MySQL Server 5.6
  • Maven 3
  • JDK 1.7
  • Tomcat 8.0.21
  • Eclipse JUNO Service Release 2

現在就讓我們開始吧！

資料庫表部分

第3步：建立資料庫模式並填充資料 

/* For Remember-Me token storage purpose */
CREATE TABLE persistent_logins (
    username VARCHAR(64) NOT NULL,
    series VARCHAR(64) NOT NULL,
    token VARCHAR(64) NOT NULL,
    last_used TIMESTAMP NOT NULL,
    PRIMARY KEY (series)
);


/*All User's gets stored in APP_USER table*/
create table APP_USER (
   id BIGINT NOT NULL AUTO_INCREMENT,
   sso_id VARCHAR(30) NOT NULL,
   password VARCHAR(100) NOT NULL,
   first_name VARCHAR(30) NOT NULL,
   last_name  VARCHAR(30) NOT NULL,
   email VARCHAR(30) NOT NULL,
   state VARCHAR(30) NOT NULL, 	
   PRIMARY KEY (id),
   UNIQUE (sso_id)
);
 
/* USER_PROFILE table contains all possible roles */  
create table USER_PROFILE(
   id BIGINT NOT NULL AUTO_INCREMENT,
   type VARCHAR(30) NOT NULL,
   PRIMARY KEY (id),
   UNIQUE (type)
);
 
/* JOIN TABLE for MANY-TO-MANY relationship*/   
CREATE TABLE APP_USER_USER_PROFILE (
    user_id BIGINT NOT NULL,
    user_profile_id BIGINT NOT NULL,
    PRIMARY KEY (user_id, user_profile_id),
    CONSTRAINT FK_APP_USER FOREIGN KEY (user_id) REFERENCES APP_USER (id),
    CONSTRAINT FK_USER_PROFILE FOREIGN KEY (user_profile_id) REFERENCES USER_PROFILE (id)
);

/* Populate USER_PROFILE Table */
INSERT INTO USER_PROFILE(type)
VALUES ('USER');

INSERT INTO USER_PROFILE(type)
VALUES ('ADMIN');

INSERT INTO USER_PROFILE(type)
VALUES ('DBA');

/* Populate one Admin User. We need only one user to demonstrate this example. You can add more as done in previous posts*/
INSERT INTO APP_USER(sso_id, password, first_name, last_name, email, state)
VALUES ('sam','abc125', 'Sam','Smith','[email protected]', 'Active');

/* Populate JOIN Table */
INSERT INTO APP_USER_USER_PROFILE (user_id, user_profile_id)
  SELECT user.id, profile.id FROM app_user user, user_profile profile
  where user.sso_id='sam' and profile.type='ADMIN';

安全部分

第4步：新增 Spring Security 組態類 

package com.yiibai.springsecurity.configuration;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

	@Autowired
	@Qualifier("customUserDetailsService")
	UserDetailsService userDetailsService;
	
	@Autowired
	DataSource dataSource;
	
	@Autowired
	public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
		auth.userDetailsService(userDetailsService);
	}
	
	@Override
	protected void configure(HttpSecurity http) throws Exception {
	  http.authorizeRequests()
	  	.antMatchers("/", "/home").permitAll()
	  	.antMatchers("/admin/**").access("hasRole('ADMIN')")
	  	.antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
	  	.and().formLogin().loginPage("/login")
	  	.usernameParameter("ssoId").passwordParameter("password")
	  	.and().rememberMe().rememberMeParameter("remember-me").tokenRepository(persistentTokenRepository()).tokenValiditySeconds(86400)
	  	.and().csrf()
	  	.and().exceptionHandling().accessDeniedPage("/Access_Denied");
	  	
	}
	
	@Bean
	public PersistentTokenRepository persistentTokenRepository() {
		JdbcTokenRepositoryImpl tokenRepositoryImpl = new JdbcTokenRepositoryImpl();
		tokenRepositoryImpl.setDataSource(dataSource);
		return tokenRepositoryImpl;
	}
}

第5步：使用war註冊springSecurityFilter

下面指定的初始化類註冊 springSecurityFilter 與應用程式 war [步驟3中建立]。 
package com.yiibai.springsecurity.configuration;

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

}

以上組態以XML組態格式為： 

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

第6步：定義UserDetailsService實現

這項服務是負責提供身份驗證細節和驗證管理。 
package com.yiibai.springsecurity.service;

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.yiibai.springsecurity.model.User;
import com.yiibai.springsecurity.model.UserProfile;

@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService{

	@Autowired
	private UserService userService;
	
	@Transactional(readOnly=true)
	public UserDetails loadUserByUsername(String ssoId)
			throws UsernameNotFoundException {
		User user = userService.findBySso(ssoId);
		System.out.println("User : "+user);
		if(user==null){
			System.out.println("User not found");
			throw new UsernameNotFoundException("Username not found");
		}
			return new org.springframework.security.core.userdetails.User(user.getSsoId(), user.getPassword(), 
				 user.getState().equals("Active"), true, true, true, getGrantedAuthorities(user));
	}

	
	private List<GrantedAuthority> getGrantedAuthorities(User user){
		List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
		
		for(UserProfile userProfile : user.getUserProfiles()){
			System.out.println("UserProfile : "+userProfile);
			authorities.add(new SimpleGrantedAuthority("ROLE_"+userProfile.getType()));
		}
		System.out.print("authorities :"+authorities);
		return authorities;
	}
	
}

SpringMVC部分

第7步: 新增控制器 

package com.yiibai.springsecurity.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HelloWorldController {

	
	@RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
	public String homePage(ModelMap model) {
		model.addAttribute("greeting", "Hi, Welcome to mysite");
		return "welcome";
	}

	@RequestMapping(value = "/admin", method = RequestMethod.GET)
	public String adminPage(ModelMap model) {
		model.addAttribute("user", getPrincipal());
		return "admin";
	}

	@RequestMapping(value = "/db", method = RequestMethod.GET)
	public String dbaPage(ModelMap model) {
		model.addAttribute("user", getPrincipal());
		return "dba";
	}

	@RequestMapping(value = "/Access_Denied", method = RequestMethod.GET)
	public String accessDeniedPage(ModelMap model) {
		model.addAttribute("user", getPrincipal());
		return "accessDenied";
	}

	@RequestMapping(value = "/login", method = RequestMethod.GET)
	public String loginPage() {
		return "login";
	}

	@RequestMapping(value="/logout", method = RequestMethod.GET)
	public String logoutPage (HttpServletRequest request, HttpServletResponse response) {
		Authentication auth = SecurityContextHolder.getContext().getAuthentication();
		if (auth != null){    
			new SecurityContextLogoutHandler().logout(request, response, auth);
		}
		return "redirect:/login?logout";
	}

	private String getPrincipal(){
		String userName = null;
		Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

		if (principal instanceof UserDetails) {
			userName = ((UserDetails)principal).getUsername();
		} else {
			userName = principal.toString();
		}
		return userName;
	}


}

第8步: 新增 SpringMVC 組態類 

package com.yiibai.springsecurity.configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.yiibai.springsecurity")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {
	
	@Bean(name="HelloWorld")
	public ViewResolver viewResolver() {
		InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
		viewResolver.setViewClass(JstlView.class);
		viewResolver.setPrefix("/WEB-INF/views/");
		viewResolver.setSuffix(".jsp");

		return viewResolver;
	}

    /*
     * Configure ResourceHandlers to serve static resources like CSS/ Javascript etc...
     *
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    }
}

第9步: 新增初始化類 

package com.yiibai.springsecurity.configuration;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

	@Override
	protected Class<?>[] getRootConfigClasses() {
		return new Class[] { HelloWorldConfiguration.class };
	}
 
	@Override
	protected Class<?>[] getServletConfigClasses() {
		return null;
	}
 
	@Override
	protected String[] getServletMappings() {
		return new String[] { "/" };
	}

}

Hibernate組態部分

第10步: 建立Hibernate組態

Hibernate組態類包含資料源層，SessionFactory和事務管理的@Bean方法。資料源屬性是取自 application.properties 檔案，包含MySQL資料庫詳細連線資訊。 
package com.yiibai.springsecurity.configuration;

import java.util.Properties;

import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.yiibai.springsecurity.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {

    @Autowired
    private Environment environment;

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "com.yiibai.springsecurity.model" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }
	
    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
        dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
        return dataSource;
    }
    
    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        return properties;        
    }
    
    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory s) {
       HibernateTransactionManager txManager = new HibernateTransactionManager();
       txManager.setSessionFactory(s);
       return txManager;
    }
}

application.properties 

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/yiibai
jdbc.username = myuser
jdbc.password = mypassword
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true

DAO, Model & Service服務

第11步: 建立模型類

使用者可以有多個角色[DBA，ADMIN，USER]。而角色可以被分配給一個以上的使用者。因此，有一個使用者和使用者組態[角色]之間存在多對多的關係。我們保持這種關係單向[使用者到使用者組態]，因為我們只是在查詢對於給使用者的角色。我們將使用使用連線表來實現多一對多關聯。 
package com.yiibai.springsecurity.model;

import java.util.HashSet;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table;

@Entity
@Table(name="APP_USER")
public class User {

	@Id @GeneratedValue(strategy=GenerationType.IDENTITY)
	private int id;

	@Column(name="SSO_ID", unique=true, nullable=false)
	private String ssoId;
	
	@Column(name="PASSWORD", nullable=false)
	private String password;
		
	@Column(name="FIRST_NAME", nullable=false)
	private String firstName;

	@Column(name="LAST_NAME", nullable=false)
	private String lastName;

	@Column(name="EMAIL", nullable=false)
	private String email;

	@Column(name="STATE", nullable=false)
	private String state=State.ACTIVE.getState();

	@ManyToMany(fetch = FetchType.EAGER)
	@JoinTable(name = "APP_USER_USER_PROFILE", 
             joinColumns = { @JoinColumn(name = "USER_ID") }, 
             inverseJoinColumns = { @JoinColumn(name = "USER_PROFILE_ID") })
	private Set<UserProfile> userProfiles = new HashSet<UserProfile>();

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getSsoId() {
		return ssoId;
	}

	public void setSsoId(String ssoId) {
		this.ssoId = ssoId;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getFirstName() {
		return firstName;
	}

	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}

	public String getLastName() {
		return lastName;
	}

	public void setLastName(String lastName) {
		this.lastName = lastName;

第12步: 建立 Dao 層 

package com.yiibai.springsecurity.dao;

import java.io.Serializable;

import java.lang.reflect.ParameterizedType;

import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

public abstract class AbstractDao<PK extends Serializable, T> {
	
	private final Class<T> persistentClass;
	
	@SuppressWarnings("unchecked")
	public AbstractDao(){
		this.persistentClass =(Class<T>) ((ParameterizedType) this.getClass().getGenericSuperclass()).getActualTypeArguments()[1];
	}
	
	@Autowired
	private SessionFactory sessionFactory;

	protected Session getSession(){
		return sessionFactory.getCurrentSession();
	}

	@SuppressWarnings("unchecked")
	public T getByKey(PK key) {
		return (T) getSession().get(persistentClass, key);
	}

	public void persist(T entity) {
		getSession().persist(entity);
	}

	public void delete(T entity) {
		getSession().delete(entity);
	}
	
	protected Criteria createEntityCriteria(){
		return getSession().createCriteria(persistentClass);
	}

}
package com.yiibai.springsecurity.dao;

import com.yiibai.springsecurity.model.User;

public interface UserDao {

	User findById(int id);
	
	User findBySSO(String sso);
	
}
package com.yiibai.springsecurity.dao;

import org.hibernate.Criteria;
import org.hibernate.criterion.Restrictions;
import org.springframework.stereotype.Repository;

import com.yiibai.springsecurity.model.User;

@Repository("userDao")
public class UserDaoImpl extends AbstractDao<Integer, User> implements UserDao {

	public User findById(int id) {
		return getByKey(id);
	}

	public User findBySSO(String sso) {
		Criteria crit = createEntityCriteria();
		crit.add(Restrictions.eq("ssoId", sso));
		return (User) crit.uniqueResult();
	}

	
}

第13步: 建立Service層 

package com.yiibai.springsecurity.service;

import com.yiibai.springsecurity.model.User;

public interface UserService {

	User findById(int id);
	
	User findBySso(String sso);
	
}
package com.yiibai.springsecurity.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.yiibai.springsecurity.dao.UserDao;
import com.yiibai.springsecurity.model.User;

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService{

	@Autowired
	private UserDao dao;

	public User findById(int id) {
		return dao.findById(id);
	}

	public User findBySso(String sso) {
		return dao.findBySSO(sso);
	}

}

檢視部分

第14步：新增檢視

login.jsp 

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

		<link rel="stylesheet" type="text/css" href="//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.2.0/css/font-awesome.css" />
	</head>

	<body>
		<div id="mainWrapper">
			<div class="login-container">
				<div class="login-card">
					<div class="login-form">
						<c:url var="loginUrl" value="/login" />
						<form action="${loginUrl}" method="post" class="form-horizontal">
							<c:if test="${param.error != null}">
								<div class="alert alert-danger">
									<p>Invalid username and password.</p>
								</div>
							</c:if>
							<c:if test="${param.logout != null}">
								<div class="alert alert-success">
									<p>You have been logged out successfully.</p>
								</div>
							</c:if>
							<div class="input-group input-sm">
								<label class="input-group-addon" for="username"><i class="fa fa-user"></i></label>
								<input type="text" class="form-control" id="username" name="ssoId" placeholder="Enter Username" required>
							</div>
							<div class="input-group input-sm">
								<label class="input-group-addon" for="password"><i class="fa fa-lock"></i></label> 
								<input type="password" class="form-control" id="password" name="password" placeholder="Enter Password" required>
							</div>
                            <div class="input-group input-sm">
                              <div class="checkbox">
                                <label><input type="checkbox" id="rememberme" name="remember-me"> Remember Me</label>  
                              </div>
							</div>
							<input type="hidden" name="${_csrf.parameterName}"
								value="${_csrf.token}" />
								
							<div class="form-actions">
								<input type="submit"
									class="btn btn-block btn-primary btn-default" value="Log in">
							</div>
						</form>
					</div>
				</div>
			</div>
		</div>

	</body>
</html>

正如你所看到的，CSRF引數需要在JSP中的EL表示式存取，所以還需要通過添將以下的程式碼新增JSP的頂部來強行執行EL表示式解析編譯： 

<%@ page isELIgnored="false"%>

admin.jsp 

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags"%>

<html>
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
	<title>Admin page</title>
</head>
<body>
	Dear <strong>${user}</strong>, Welcome to Admin Page.
	
	<sec:authorize access="isFullyAuthenticated()">
		<label><a href="#">Create New User</a> | <a href="#">View existing Users</a></label>
	</sec:authorize>
	<sec:authorize access="isRememberMe()">
		<label><a href="#">View existing Users</a></label>
	</sec:authorize>
 
	<a href="<c:url value="/logout" />">Logout</a>
</body>
</html>
以下提到的檢視在這個貼文中不需要，只是在這裡提及，作為一個完整的補充。

welcome.jsp 

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

	<link href="<c:url value='/static/css/app.css' />" rel="stylesheet"></link>
</head>
<body>
	<div class="success">

		This is a welcome page.
	</div>
</body>
</html>

dba.jsp

	<a href="<c:url value="/logout" />">Logout</a>
</body>
</html>

accessDenied.jsp 

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

</head>
<body>
	Dear <strong>${user}</strong>, You are not authorized to access this page
	<a href="<c:url value="/logout" />">Logout</a>
</body>
</html>

第16步 - 構建和部署應用程式

現在構造 war(通過 eclipse/m2eclipse)或通過Maven的命令列(mvn clean install)。部署WAR檔案到Servlet3.0容器。由於這裡我使用的是在 eclipse 中組態 Tomcat，可以直接發佈到 Tomcat 服務容器中。如果不知道怎麼使用，可以參考：/20/223/8584.html

執行應用程式

開啟瀏覽器並存取 -  http://localhost:8080/SpringSecurityRememberMeAnnotation/admin

系統將提示您登入，如下圖中所示 - 

使用"記住我" 驗證登入(使用使用者：kenny/123456)，您將獲得管理員檢視，如下所示 - 

驗證檢視 Cookies。開啟谷歌瀏覽器設定/顯示高階設定/內容設定/所有Cookie和網站資料顯示本地主機。你會發現有兩個 cookies ，一個用於當前對談[JSESSIONID]，一個用於"記住我"的身份驗證。

點選"記住我"(remember-me)，檢視cookie詳細資訊。你可以看到 cookie 的有效期是一天(如在安全組態設定)。

現在檢視 persistent_logins 表中資料。應該有當前使用者的 Cookies 記錄資訊。

現在退出登入，如下圖中所示  - 

現在再試嘗試開啟：http://localhost:8080/SpringSecurityRememberMeAnnotation/admin，應該直接登入，而不再需要使用輸入使用者名和密碼登入。

還可以看到 「Create New User」 選項不可用，這是因為一個是僅當使用者(使用登入名/密碼，例如)有許可權的認證才能使用此功能，現在從Chrome中刪除 "記住我" 的cookie(如前所示)，並再次嘗試存取：http://localhost:8080/SpringSecurityRememberMeAnnotation/admin，程式應該提示您登入。
就這麼多，下一篇文章我們將來學習使用 Spring Security 的 @PreAuthorize，@PostAuthorize，@Secured和Spring EL表示式的方法級的安全控制。
