搭建springmvc项目，在写测试类的时候，视图解析器一直转发不成功

首先我的一些配置文件如下

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">

    <!-- 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>
        <!--加载的时候创建-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!--设置处理规则-->
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>


</web-app>

springmvc.xml

<?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: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-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

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

    <!--配置视图解析器，解析规则为  prefix+返回的String+suffix-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

    <!--返回类，自动转为json-->
    <mvc:annotation-driven>
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <!-- 用于避免响应头过大 -->
                <property name="writeAcceptCharset" value="false"/>
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/plain;charset=UTF-8</value>
                        <value>text/html;charset=UTF-8</value>

            </bean>
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                <property name="supportedMediaTypes">

                        <value>text/json;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

</beans>

index.jsp

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

success.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

    <title>Title</title>

TestController

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";
    }
}

目录结构

 

这没毛病啊，这么就死活跳转不成功了呢，而且页面上显示的都是success

排查了各个配置文件，没问题，那应该是controller的问题，原来我在controller类方法上顺手加了 @ResponseBody 标签，前后端分离的开发习惯欲哭无泪啊

网上对这个标签的解释是这样的

@requestBody注解常用来处理content-type不是默认的application/x-www-form-urlcoded编码的内容，比如说：application/json或者是application/xml等。一般情况下来说常用其来处理application/json类型

好吧，删了这个标签，idea出现了一个很友好的小图标

再次启动项目跳转，成功
