Spring映射失败：HTTP状态404（请求的资源不可用）

标签： java spring jsp spring-mvc http-status-code-404

我知道有数百万种可能的解决方案，我尝试了很多，但仍然没有任何好处。

我正在尝试将基本控制器映射到url并返回JSP视图。它显示带有描述的HTTP状态404请求的资源不可用。请帮忙。

控制器 

package controllers;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;


@Controller
public class HomePageController {

@RequestMapping(value = "/twenty-eight/index", method = RequestMethod.GET)
public ModelAndView homePage(HttpServletRequest httpServletRequest, 
        HttpServletResponse httpServletResponse){
    ModelAndView mav = new ModelAndView("HomePage");
    System.out.println("Going to index page...");
    return mav;
    }
}

的web.xml 

<web-app id="WebApp_ID" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<display-name>Spring Web MVC Application</display-name>
<servlet>
    <servlet-name>dispatcher-servlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

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

servlet的context.xml中 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

JSP视图 

<!DOCTYPE html>
<html>
<head>
    <title>HTML5 Login</title>
    <link rel="stylesheet" href="CSS/normalize.css">
    <link rel="stylesheet" href="CSS/style.css">

<body>
    <h1>Working Fine</h1>

</html>
