java+postgresql+swagger-单表批量和循环insert、delete操作(八)

一、循环写入：

入参json格式：

复制代码

2、Mapper：

复制代码

@Mapper
public interface TmDeviceStatusMapper extends BaseMapper<TmDeviceStatus> {
    @Select("select * from tm_devicestatus where devicenumber = #{deviceNumber} and pointsource=#{pointSource}")
    TmDeviceStatus existsTmDeviceStatus(@Param("deviceNumber") String deviceNumber, @Param("pointSource") short pointSource);
}

3、Service：

复制代码

package com.example.springbootmybatisplus.service;

import com.alibaba.fastjson.JSONObject;
import com.example.springbootmybatisplus.entity.TmDeviceStatus;
import com.example.springbootmybatisplus.mapper.TmDeviceStatusMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.stream.Collectors;

@Service
public class TmDeviceStatusService {
    @Autowired
    private TmDeviceStatusMapper tmDeviceStatusMapper;

    private static final Logger log = LoggerFactory.getLogger(TmDeviceStatusService.class);

    public void insertTmDeviceStatus(String msg) {
        try {
            List<TmDeviceStatus> jsonArray = JSONObject.parseArray(msg, TmDeviceStatus.class);
            for (int i = 0; i < jsonArray.size(); i++) {
                TmDeviceStatus tmDeviceStatus = jsonArray.get(i);
                TmDeviceStatus tmDeviceStatus1 = tmDeviceStatusMapper.existsTmDeviceStatus(tmDeviceStatus.getDeviceNumber(), tmDeviceStatus.getPointSource());
                if (tmDeviceStatus1 != null) {
                    tmDeviceStatusMapper.deleteById(tmDeviceStatus.getDeviceNumber());
                    log.info("设备：{}的定位信息在表中存在，删除此设备定位信息", tmDeviceStatus.getDeviceNumber());
                }
                tmDeviceStatusMapper.insert(tmDeviceStatus);
                log.info("设备：{}的定位信息已写入表中", tmDeviceStatus.getDeviceNumber());
            }
        } catch (Exception e) {
            log.error("异常信息：" + e.getMessage());
        }
    }
}

4、Controller：

复制代码

package com.example.springbootmybatisplus.contronller;

import com.example.springbootmybatisplus.entity.TmDeviceStatus;
import com.example.springbootmybatisplus.service.TmDeviceStatusService;
import io.swagger.annotations.Api;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/tm-devicestatus")
@Api(tags = "设备状态")
public class TmDeviceStatusController {
    @Autowired
    private TmDeviceStatusService tmDeviceStatusService;

    @PostMapping("/insert1")
    public ResponseEntity<String> insert1(@RequestBody String msg) {
        try {
            tmDeviceStatusService.insertTmDeviceStatus(msg);
            return ResponseEntity.status(HttpStatus.CREATED).body("Success");
        } catch (Exception e) {
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("Failed");
        }
    }

}

5、调用接口打印日志：

二、批量操作：

入参json格式：

复制代码

[{"batteryPct": 88,"deviceLat": 34.331913,"deviceLng": 113.278743,"deviceNumber": "swaggertest01","deviceState": 2,"lastTime": "2025-04-10 02:57:09","locationTime": "2025-04-10 02:57:09","locationType": 1,"pointSource": 9999,"speed": 23.2},{"batteryPct": 88,"deviceLat": 34.331913,"deviceLng": 113.278743,"deviceNumber": "swaggertest02","deviceState": 2,"lastTime": "2025-04-10 02:57:09","locationTime": "2025-04-10 02:57:09","locationType": 1,"pointSource": 9999,"speed": 23.2}]

1、实体：

和上面的一样。

2、Mapper：

复制代码

@Mapper
public interface TmDeviceStatusMapper extends BaseMapper<TmDeviceStatus> {
    int deleteTmDeviceStatusList(@Param("list") List<String> devices);

    int insertTmDeviceStatusBatch(@Param("list") List<TmDeviceStatus> deviceStatus);
}

3、xml：
