Spring STS捆绑包不能触发控制器

Question

我尝试使用Spring Tools Suite设置一个简单的弹簧网，但我无法触发Controller类，我不确定是什么错，当我走http://localhost:8080/时，没关系，意味着我的服务器已启动，但当我转到http://localhost:8080/MVCTest/test12时，它显示找不到页面。

我的pom.xml没问题，我只有那里的所有库，我试图使用类符号，而不是XML。

设置

服务器：Pivotal tc Server Developer Edition v3.2 [已启动]

从控制台登录，似乎没问题：

Jan 14, 2017 12:29:34 PM org.apache.catalina.startup.Catalina load
INFO: Initialization processed in 1108 ms
Jan 14, 2017 12:29:35 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 875 ms

我的控制器代码：

package com.app1.controller;

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

@Controller
public class EmployeeController {

    @RequestMapping("/test12")
    public void test12()
    {
        System.out.println("Welcome");
    }
}

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>MVCTest</display-name>

   <servlet>
      <servlet-name>spring-dispatcher</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
   </servlet>

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

</web-app>

servlet的context.xml中

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

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

您没有必要的Spring Application Context定义文件。此文件确保Spring容器执行组件扫描，以便自动发现使用@Controller注释的任何代码。
