1、引入jar包

spring-corecommons-logging-1.2.jar
spring-beans-3.2.5.RELEASE.jar
spring-context-3.2.5.RELEASE.jar
spring-core-3.2.5.RELEASE.jar
spring-expression-3.2.5.RELEASE.jar
spring-webspring-web-3.2.5.RELEASE.jar
spring-webmvcspring-webmvc-3.2.5.RELEASE.jar
2、配置
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>springmvc02</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!-- 注册SpringMVC核心控制器 -->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>

<!-- 注册Spring的编码过滤器，位于spring-web的jar包中 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>


springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<!-- <import resource="com/rk/config/spring-test.xml"/>     -->

<!-- Action控制器 -->
<context:component-scan base-package="com.rk.action"></context:component-scan>

<!-- 基于注解的映射器(可选) -->
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>

<!-- 基于注解的适配器(可选) -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

<!-- 视图解析器(可选) -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"/>

</beans>


3、创建HelloWorldAction控制器
HelloWorldAction.java

package com.rk.action;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloWorldAction {
@RequestMapping(value="/test")
public String test(Model model) throws Exception{
System.out.println("HelloWorldAction.test()");
model.addAttribute("message", "这是我的第二个SpringMVC应用程序！");
return "/index.jsp";
}

}


4、JSP页面
修改WebRoot/下的index.jsp页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Index Page</title>
</head>

<body>
This is my JSP page. <br>
${message }
</body>
</html>
