InternalResourceViewResolver
用於將提供的URI解析為實際URI。下面的範例演示如何在Spring Web MVC框架中使用SpringResultViewResolver
。 InternalResourceViewResolver
允許對映網頁與請求。
所下所示組態 -
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;
@Controller
@RequestMapping("/hello")
public class HelloController{
@RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Spring MVC Framework 對映網頁與請求範例!");
return "hello";
}
}
URL對映組態檔案如下 -
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
例如,使用上面的組態,如果URI
:
/hello
請求,DispatcherServlet
會將請求轉發到字首+ view-name + suffix = /WEB-INF/jsp/hello.jsp
。首先,讓我們使用Eclipse IDE,並按照以下步驟使用Spring Web Framework開發基於動態表單的Web應用程式:
com.yiibai.springmvc
包下建立一個Java類HelloController
。jsp
子檔案夾下建立一個檢視檔案:hello.jsp
。完整的專案檔案目錄結構如下所示 -
HelloController.java 的程式碼如下所示 -
package com.yiibai.springmvc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;
@Controller
@RequestMapping("/hello")
public class HelloController{
@RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Spring MVC Framework 對映網頁與請求範例!");
return "hello";
}
}
InternalResourceViewResolver-servlet.xml 的程式碼如下所示 -
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="com.yiibai.springmvc" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
hello.jsp 的程式碼如下所示 -
<%@ page contentType="text/html; charset=UTF-8" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h2>${message}</h2>
</body>
</html>
完成建立源和組態檔案後,發布應用程式到Tomcat伺服器。
現在啟動Tomcat伺服器,當存取URL => http://localhost:8080/InternalResourceViewResolver/hello , 如果Spring Web應用程式沒有問題,應該看到以下結果:
