entity和mapper里的都是 mybatis generator自己生成的
package com.music.demo.service;
import com.music.demo.entity.User;
import com.music.demo.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UserService {
@Autowired
private UserMapper userMapper;
public User selectById(int id){
return userMapper.selectByPrimaryKey(id);
}
}
package com.music.demo.controller;
import com.music.demo.entity.User;
import com.music.demo.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
@RestController
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/test")
public ModelAndView test( User user){
ModelAndView modelAndView = new ModelAndView();
User user1 = userService.selectById(user.getId());
modelAndView.addObject("name",user1.getUsername());
modelAndView.setViewName("test");
return modelAndView;
}
}
最后在WEB-INF建一个jsp包,在包里写test.jsp
