Question

每次执行Spring应用程序时都会收到404错误。我使用eclipse创建了动态Web项目。我是春天新手并且第一次使用eclipse。请帮忙解决这个问题。

我的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_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>SpringBasic</display-name>

    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    </web-app>

弹簧servlet.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"  
   xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"  
    xmlns:jpa="http://www.springframework.org/schema/data/jpa"
    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.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">

<context:component-scan base-package="com.bt.controller" />
<mvc:annotation-driven />



      <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name = "prefix" value = "/WEB-INF/jsp/" />
      <property name = "suffix" value = ".jsp" />
   </bean>


</beans>

myController的

  package com.bt.controller;

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

@Controller
public class MyController {


     @RequestMapping("/")
     @ResponseBody
      public ModelAndView loadhellopage() {
         System.out.println("controller");
        String msg="Finally";
        ModelAndView mav=new ModelAndView("hellopage");
        mav.addObject("msg", "Finally");
         return mav;
      }

}

hellopage.jsp：

  <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    ${message} 
</body>
</html>

这是我的文件夹结构：

还包括WEB-INF下的lib文件夹中的所有jar文件。

在apache tomcat上运行项目时，它给出了404错误

执行spring MVC时出现404错误
