springmvc 返回 404 解决

Idea Maven springmvc spring 项目搭建中/url 能够访问controller，而且能返回正确的ModelAndView，可是页面老是显示404

项目结构：

 

 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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">
  <context-param>
    <param-name>contextConfigLocation</param-name>

  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <servlet>
    <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>WEB-INF/springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

                           ">
</beans>

springmvc.xml

                           http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd
                           ">
    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
    <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>-->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    <bean name="/queryHello" class="lime.spring.controller.HelloController"/>
</beans>

Controller

package lime.spring.controller;


import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

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

public class HelloController implements Controller {

    public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("msg","I like Tome too");
        modelAndView.setViewName("hello");
        return modelAndView;
    }
}

1. 有的说是ModelAndView包导错了。个人对着呢

2. 有的说路径错了。个人对着呢

3.配置org.springframework.web.servlet.DispatcherServlet时，<url-pattern>/</url-pattern>须要是“/”,不能是其余的，如“/*”就会返回404，至于为何，待我看看源码再说。阿西吧

啦啦啦
