2、Dao层(dao)
package com.zzg.springdata.dao;import org.springframework.data.jpa.repository.JpaRepository;import com.zzg.springdata.model.User;public interface UserDao extends JpaRepository<User, Long> {}
3、service层(service)
package com.zzg.springdata.service;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import com.zzg.springdata.dao.UserDao;import com.zzg.springdata.model.User;@Service@Transactionalpublic class UserService {	@Autowired    private UserDao userDao;        public String add(User user){        userDao.save(user);        return "添加成功！";    }        public String addUser(){        User user = new User();        user.setAge(18);               user.setCreateTime("2017-03-07 00:53:12");        user.setLastLoginTime("2017-03-07 00:54:12");        user.setLoginName("zzg");        user.setName("小周");        user.setPassword("123456");        user.setRealName("周*刚");        user.setRole("一级管理员");        userDao.save(user);        return "添加成功！";    }        public User getOneUser(Long id){        return userDao.findOne(id);    }}
4、controller层(controller)
package com.zzg.springdata.controller;import javax.servlet.http.HttpServletRequest;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.http.MediaType;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import com.zzg.springdata.model.User;import com.zzg.springdata.service.UserService;@Controller    public class UserController {	 	@Autowired	    private UserService userService;	    	    @RequestMapping(value = "/saveUser",	            method = RequestMethod.GET	           )	    @ResponseBody	    public String saveUser(HttpServletRequest  request){	    	User user =new User();	    		    	user.setAge(Integer.parseInt(request.getParameter("age")));	    	user.setCreateTime(request.getParameter("createTime"));	    	user.setLastLoginTime(request.getParameter("lastLoginTime"));	    	user.setName(request.getParameter("name"));	    	user.setPassword(request.getParameter("password"));	    	user.setRealName(request.getParameter("realName"));	    	user.setRole(request.getParameter("role"));	    	user.setLoginName(request.getParameter("loginName"));	    	System.out.println(user.getCreateTime()+"//"+user.getLastLoginTime());	        return userService.add(user);	    }	    	    @RequestMapping(value = "/addUser",	            method = RequestMethod.GET	           )	    @ResponseBody	    public String add(){	        return userService.addUser();	    }	    	    @RequestMapping(value = "/user",	            method = RequestMethod.GET	           )	    @ResponseBody	    public User add(Long id){	        return userService.getOneUser(id);	    }}数据请求结果展示：
1、新增用户数据：/saveUser
2、添加用户数据：/add
3、查询特点用户信息:/user
