一：web.xml配置

<!-- Spring MVC配置 -->

  <servlet>

	<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>

	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

	<init-param>

		<param-name>contextConfigLocation</param-name>

<pre name="code" class="html">                <!-- 相应的mvc配置文件地址： -->

<param-value>/WEB-INF/conf/web-application-config.xml</param-value></init-param> </servlet> <servlet-mapping><servlet-name>Spring MVC Dispatcher Servlet</servlet-name><url-pattern>*.do</url-pattern> </servlet-mapping>



二：mvc配置文件



<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:p="http://www.springframework.org/schema/p"

    xmlns:context="http://www.springframework.org/schema/context"

    xmlns:mvc="http://www.springframework.org/schema/mvc"

    xsi:schemaLocation="

        http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans.xsd

        http://www.springframework.org/schema/context

        http://www.springframework.org/schema/context/spring-context.xsd

        http://www.springframework.org/schema/mvc

        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<!-- 默认扫描的包路径 -->

    <context:component-scan base-package="com.sofmit.psa"/>

    <!-- 加入注解驱动 -->

    <mvc:annotation-driven/>

    <!-- 定义跳转的文件的前后缀 -->

	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/WEB-INF/jsp/" />

        <!-- 默认转向页面后缀 -->

        <property name="suffix" value=".jsp" />

    </bean>  

</beans>


三：后台代码



package com.sofmit.psa.central.test.test;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

@RequestMapping("/central/test")

public class TestAction {

	@RequestMapping("/test")

	public String test(){

		return "/test";

	}

}
