Users 實體類
package org.it123.sdubbo.web.model;
import com.baomidou.mybatisplus.annotation.TableName;
@TableName(value = "tab_sys_users")
public class Users {
private String name;
private String password;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
UsersService 接口
package org.it123.sdubbo.web.service;
import org.it123.sdubbo.web.model.Users;
import org.springframework.stereotype.Service;
@Service
public interface UsersService {
int add(Users users);
}
UsersServiceImpl 實現類
package org.it123.sdubbo.web.service.impl;
import org.it123.sdubbo.web.dao.UsersDao;
import org.it123.sdubbo.web.model.Users;
import org.it123.sdubbo.web.service.UsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UsersServiceImpl implements UsersService {
@Autowired
private UsersDao usersDao;
@Override
public int add(Users users) {
return usersDao.insert(users);
}
}
操作層類
package org.it123.sdubbo.web.dao;
import org.it123.sdubbo.web.model.Users;
import org.springframework.stereotype.Repository;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
@Repository
public interface UsersDao extends BaseMapper<Users> {
}
控制器層
package org.it123.sdubbo.web.controller;
import org.it123.sdubbo.web.model.Users;
import org.it123.sdubbo.web.service.UsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class UsersController {
@Autowired
private UsersService usersService;
@GetMapping("/demo")
public String demo() {
Users users = new Users();
users.setName("IT123私塾");
users.setPassword("123456");
int mum = usersService.add(users);
if (mum > 0) {
return "增加成功";
} else {
return "增加失敗";
}
}
}
入口文件啟動類
package org.it123.sdubbo.web;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
@EnableDubbo
@SpringBootApplication
@MapperScan("org.it123.sdubbo.*.dao")
public class webApplication {
public static void main(String[] args) {
SpringApplication.run(webApplication.class, args);
}
}
