首先個人一些配置文件以下html

web.xmljava

<?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">

    <!-- 配置 DispatcherServlet -->
    <servlet>
        <servlet-name>dispatcherServlet</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>
        <!--加載的時候建立-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!--設置處理規則-->
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>


</web-app>

springmvc.xmlweb

    <!-- 配置自定掃描的包 -->
    <context:component-scan base-package="controller"></context:component-scan>

                <!-- 用於避免響應頭過大 -->

</beans>

index.jspspring

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>aaaa</title>
</head>
<body>
 <a href="/test/hello.action">hello</a>
</body>

success.jspjson

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body> 轉發成功 ----111
</body>
</html>

TestController後端

package controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; @Controller @RequestMapping("/test") public class TestController { @RequestMapping("hello.action") @ResponseBody public String hello(){ return "success"; } }
