Question

我的项目有问题。当我浏览http://localhost:8080/user/form以显示UserForm时，会出现以下错误：

警告：找不到带有URI [/ user / form]的HTTP请求的映射 DispatcherSe rvlet，名称为'userservice'

此处归档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));
    }


}

此处归档userservice-servlet.xml
