Spring Boot MyBatis Postgres 实现对数据表增删改查操作（采用注解方式）

1.创建Java实体类

package com.example.server;public class SceneService {private  String servicename;private  ServiceTypeEnum servicetype;private  String serviceurl;public String getServicename() {return servicename;}public void setServicename(String servicename) {this.servicename = servicename;}public ServiceTypeEnum getServicetype() {return servicetype;}public void setServicetype(ServiceTypeEnum servicetype) {this.servicetype = servicetype;}public String getServiceurl() {return serviceurl;}public void setServiceurl(String serviceurl) {this.serviceurl = serviceurl;}
}

2.创建Mapper接口

package com.example.server; import org.apache.ibatis.annotations.*;import java.util.Map;@Mapper
public interface SceneServicesMapper {//按名称查询@Select("select * from sys_scene_services_tb where servicename=#{name}")public SceneService selectServiceByName(String servicename);//查询服务列表@Select("select * from sys_scene_services_tb")@MapKey("servicename")public Map<String,SceneService> selectServices();//删除@Delete("delete from sys_scene_services_tb where servicename=#{name}")public int deleteService(String servicename);//修改@Update("update sys_scene_services_tb set servicetype=#{servicetype}, serviceurl=#{serviceurl} where servicename=#{servicename}")public int updateService(SceneService sceneService);//插入@Insert("insert into sys_scene_services_tb(servicename,servicetype,serviceurl) values(#{servicename},#{servicetype},#{serviceurl})")public int insertService(SceneService sceneService);}

3. 创建控制类Controller

package com.example.server.controller;import com.example.server.SceneService;
import com.example.server.SceneServicesMapper;
import net.minidev.json.JSONObject;
import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;import java.util.Map;@RestControllerpublic class SceneServicesController {@AutowiredSceneServicesMapper sceneServicesMapper;//查询@RequestMapping("/get/{name}")public SceneService getServiceByName(@PathVariable("name") String name) {return  sceneServicesMapper.selectServiceByName(name);}// 查询服务列表@RequestMapping("/services")public Map<String,SceneService> getServices(){return (Map<String, SceneService>) sceneServicesMapper.selectServices();}//删除@RequestMapping("/delete/{name}")public String deleteService(@PathVariable("name") String name){sceneServicesMapper.deleteService(name);return "删除成功！";}//插入@RequestMapping("/insert")public SceneService insertService(SceneService sceneService){sceneServicesMapper.insertService(sceneService);return sceneService;}//修改@RequestMapping("/update")public SceneService updateService(SceneService sceneService){sceneServicesMapper.updateService(sceneService);return sceneService;}}
