Java Tomcat 404:请求的资源不可用

我正在尝试创建简单的RESTful web服务。我的war文件构建成功，并且在tomcat上启动时没有错误

但是，例如，当我打电话给某个服务时http://localhost:8080/fxmonitor/service/account/, 我给出一个错误： 类型状态报告 消息 说明请求的资源不可用

在tomcat日志中： 10.08.2014 14:31:07 org.springframework.web.servlet.DispatcherServlet noHandlerFound 警告：在名为“fxmonitor”的DispatcherServlet中找不到URI为[/fxmonitor/service/account/Hello World1FuuUu]的HTTP请求的映射

My web.xml：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"

所以我通过在方法中添加nig@ResponseBody解决了这个问题：

@RequestMapping(method= RequestMethod.GET)
    public @ResponseBody String  getAccount(){
        return "Hello world1FUUUUU";
    }

package com.pammonitor.web;

/**
 * Created by user on 10.08.14.
 */

import com.pammonitor.dao.AccountDAO;
import com.pammonitor.entity.AccountEntity;
import com.pammonitor.model.AccountModel;
import org.eclipse.persistence.annotations.ChangeTracking;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.annotation.Resource;

@Controller
@RequestMapping("/service/account/")
public class AccountController {

    @RequestMapping(method= RequestMethod.GET)
    public String  getAccount(){
        return "Hello world1FUUUUU";
    }

    public AccountDAO getAccountDAO() {
        return accountDAO;
    }

    public void setAccountDAO(AccountDAO accountDAO) {
        this.accountDAO = accountDAO;
    }
}

@RequestMapping(method= RequestMethod.GET)
    public @ResponseBody String  getAccount(){
        return "Hello world1FUUUUU";
    }
