SpringMVC配置

1.导入相关jar

2.配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee                       
  http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <!-- SpringMVC 前端控制器,入口 -->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 自启动-在启动tomcat时立即加载对应的Servlet -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
</web-app>

3. 在WEB-INF下新建<servlet-name>-servlet.xml配置文件,并配置内容(与web.xml中servlet-name名字一致)

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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/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">
    <!-- 告诉SpringMVC的注解在哪里 -->
    <context:component-scan base-package="com.sixfly.controller"></context:component-scan>
    <!-- 配置标签让SPringMVC注解生效,创建注解解析器. -->
    <mvc:annotation-driven/>
</beans>

4.编写controller类

package com.sixfly.controller;

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

@Controller
public class SixController {
  @RequestMapping("show.do")
  public String show(){
    System.out.println("执行show");
    return "index.jsp";//执行完操作跳转的界面
  }
}

5.测试结果
