需要您的帮助以下错误。
我正在尝试使用Spring MVC从index.jsp重定向到第二个页面。但得到这个错误。

HTTP Status 404 - /redirect.do
description The requested resource is not available.

我的控制器类是

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

@Controller
public class MainInvController {

    @RequestMapping(value="/redirect")// , method = RequestMethod.GET
    @ResponseBody
    public String redirect() {
        System.out.println("redirect");
        return "bravo";
    }
}

控制器只是尝试将用户请求重定向到第二页。
我的web.xml是

 "http://java.sun.com/dtd/web-app_2_3.dtd" >

spring-master.xml作为

index.jsp如下所示。

<html>
<body>
<h2>Hello World!</h2>
<h2>Spring Page Redirection</h2>
<p>Click below button to redirect the result to new page</p>
<form method="GET" action="/redirect.do">

    <tr>
    <td>
    <input type="submit" value="Redirect Page"/>
