依赖的jar包

commons-logging-1.2.jar
spring-aop-4.2.4.RELEASE.jar
spring-beans-4.2.4.RELEASE.jar
spring-context-4.2.4.RELEASE.jar
spring-core-4.2.4.RELEASE.jar
spring-expression-4.2.4.RELEASE.jar
spring-web-4.2.4.RELEASE.jar
spring-webmvc-4.2.4.RELEASE.jar

配置web.xml

  <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>/</url-pattern>  </servlet-mapping>

创建两个JSP页面

主页面index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body>    <h1><a href="hello">skip</a></h1></body></html>

跳转页面success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body>    <p>hello, world.</p></body></html>

创建类

在com.gwx.springmvc包下创建一个类

package com.gwx.springmvc;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class MySpringMVC {    @RequestMapping("/hello")    public String skip() {        System.out.println("holle");        return "success";    }}

SpringMVC配置文件

在src下创建配置文件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">    <!-- 配置自动扫描解析 -->    <context:component-scan base-package="com.gwx.springmvc"></context:component-scan>    <!-- 如果使用了注释，必须配置 -->    <mvc:annotation-driven></mvc:annotation-driven>    <!-- 配置视图解析 -->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <!-- 前缀 -->        <property name="prefix" value="/"></property>        <!-- 后缀 -->        <property name="suffix" value=".jsp"></property>    </bean></beans>
