Spring 错误：找不到URI为的HTTP请求的映射。如何修复它？

我的项目有问题。当我浏览

http://localhost:8080/user/form

显示用户表单，然后出现以下错误：

警告：在中找不到URI为[/user/form]的HTTP请求的映射 名为“userservice”的DispatcherSe rvlet

这里是文件

UserRestServiceController.java

package edu.java.spring.service.user.controller;

import org.springframework.beans.factory.annotation.Autowired;
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 org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.View;

import edu.java.spring.service.user.dao.UserDao;
import edu.java.spring.service.user.model.User;

@Controller
public class UserRestServiceController {
    @Autowired
    private UserDao userDao;
    @Autowired
    private View jsonView;
    @RequestMapping(value="/user/form,",method = RequestMethod.GET)
    public ModelAndView user(){
//      System.out.println("anh yeu em ");
        return new ModelAndView("UserForm","User",new User());
    }
    @RequestMapping(value="/user/json/{username}")
    public ModelAndView loadUser(@PathVariable("username")String name){
        return new ModelAndView(jsonView,"data",userDao.loadUser(name));
    }

真的
类路径：User.hbm.xml

在类级别添加

@RequestMapping（value=“/user”）

并在方法级别删除该部分路径

在

userservice servlet.xml中添加
，我已经添加了AliDehghani，但仍然显示相同的错误
