先建立一個ssh2的專案
1.1 hibernate相關(5.2.12.Final)
hibernate-core
hibernate-c3p0（數據庫連線池）
hibernate-ehcache
mysql-connector-java(5.1.44)
1.2 spring相關(5.0.1.RELEASE)
spring-context
spring-orm
spring-web
spring-aspects
注：建立spring的XML檔案時，需要新增beans/aop/tx/context標籤支援
各依賴說明：
spring-context
建立spring上下文
spring-orm
org.springframework.orm.hibernate5.LocalSessionFactoryBean
dataSource：指定數據源
hibernateProperties：指定hibernate相關屬性，如：dialect/show_sql/format_sql
mappingResources：指定實體對映檔案
注1：本章採用將hibernate設定全部交給spring管理，因此專案中不再有hibernate.cfg.xml檔案
org.springframework.orm.hibernate5.HibernateTemplate
org.springframework.orm.hibernate5.support.HibernateDaoSupport
測試一：執行測試類Test1,測試hibernate與spring的整合
spring-web
org.springframework.web.context.ContextLoaderListener
contextConfigLocation:classpath:applicationContext-*.xml
org.springframework.web.context.support.WebApplicationContextUtils
測試二：存取test2.jsp，測試spring與WEB專案的整合
spring-aspects
spring的AspectJ依賴，解析事務切點
1.3 struts2相關(2.5.13)
struts2-core
struts2-spring-plugin
struts2與spring整合的外掛
將action設定到spring中,struts的action標籤的class屬性填寫spring中bean的名字或id
1.4 log設定
1.4.1 log4j(1.X版)
不建議使用
1.4.2 log4j2(2.9.1)
log4j-core
log4j-api
log4j-web
不建議使用
1.4.3 log4j2 + slf4j(使用ehcache開啓hibernate二級快取必須使用第二種方式設定日誌)
注1：本章使用第三種方式設定日誌，即log4j2 + slf4j
1.5 other
junit(4.12)
javax.servlet-api(4.0.0)
1.6 jstl
jstl(1.2)
standard(1.1.2)
1.7 jsp自定義標籤依賴(必須與tomcat的版本一致)
tomcat-jsp-api
注1：如何解決專案中不支援EL表達式的問題？將web.xml的DTD的版本由2.3升級到3.0即可。因爲web2.3是不支援EL表達式的

3 整合hibernate
1.1 注入數據庫組態檔
db.properties
db.username=root
db.password=
db.driverClass=com.mysql.jdbc.Driver
db.jdbcUrl=jdbc:mysql://localhost:3306/t243
db.initialPoolSize=10
db.maxPoolSize=20
db.minPoolSize=5
db.maxIdleTime=60
db.acquireIncrement=5
db.maxStatements=0
db.idleConnectionTestPeriod=60
db.acquireRetryAttempts=30
db.breakAfterAcquireFailure=true
db.testConnectionOnCheckout=false
1.2 設定c3p0連線池
1.3 註冊LocalSessionFactoryBean
1.4 spring宣告式事物
宣告式事務設定
1) 必須先修改spring組態檔的宣告部分，新增對aop標籤和tx標籤的支援
設定SessionFactory(spring和hibernate整合時已完成)
設定事務管理器
HibernateTransactionManager
設定事務的傳播特性(tx)
add
edit
del
load|list
事務傳播特性(PROPAGATION_REQUIRED|readOnly)
設定自動代理
a) 參照環繞通知txAdvice
b) 定義一個切入點
execution(* *…Biz.(…))
a:返回值不限 b:包名不限 c:介面名以Biz結尾 d:方法名及參數不限
c) 自動代理的原理
在spring上下文初始化完成以後，自動代理會逐個檢查spring上下文中JavaBean實現的介面是否滿足自動代理的條件，如果滿足條件,則將此bean和通知結合生成一個代理物件，並以此代理物件替換spring上下文中的bean,之後你存取的就是代理物件了
