无法在tomcat上运行spring web应用程序（eclipse）

我创建了一个非常小的spring web应用程序，但无法使用eclipse在tomcat上部署它。我可以在日志中看到该Web应用程序已初始化。然而，tomcat实际上并没有部署它，如果我尝试去URL，我得到一个404错误资源不可用。我在这里错过了什么吗？无法在tomcat上运行spring web应用程序（eclipse）

的HomeController

package com.doyleisgod.mnpui.controllers; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.ModelMap; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
public class HomeController { 
    @RequestMapping("/home.jsp") 
    public String home (ModelMap model){ 
     model.addAttribute("message", "Welcome"); 
     return "home"; 
    } 
}

回到Home.jsp

您是否试图查看您的项目部署在哪里？ – 2014-09-03 12:48:00

@JavaDev它被解析到其他应用程序所在的tomcat的webapps文件夹中。点击“在服务器上运行”后，我可以看到mnpui文件夹出现在webapps – 2014-09-03 13:00:28

中你试图访问什么网址？ – 2014-09-03 13:04:39

您需要更改添加下面一行的web.xml文件

<servlet-mapping> 
     <servlet-name>jsp</servlet-name> 
     <url-pattern>/WEB-INF/jsp/*</url-pattern> 
</servlet-mapping>

大多数servlet容器有一个默认的映射从*.jsp到他们自己的JSP处理器。

我有另一个春天项目，它有相同的servlet映射，它工作正常。 – 2014-09-03 14:11:19
