小弟新手，刚刚才学spring mvc，今天写了个简单de程序总是报错。
这是我的web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name></display-name>
<!-- 配置Spring MVC DispatcherServlet -->
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup> <!-- start dispatcherservlet at the beginning -->
</servlet>
<!-- 配置DispatcherServlet所需要拦截的 url -->
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
MVC-servlet.xml 文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</beans>
Welcometroller文件
package org.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class WelcomeController {
@RequestMapping({"/hello","/"})
public String hello(){
System.out.println("hello");
return "hello";
}
}
最后是一个简单的hello.jsp文件。
每次打开输入地址就报错。
求大家帮忙。

解决了？
------解决思路----------------------
@RequestMapping({"/hello","/"})改成@RequestMapping(value ={"/hello","/"})试试
