import org.springframework.stereotype.Component;


import javax.annotation.PostConstruct;
import javax.annotation.Resource;


@Component
public class WebSocketDbService {
    


// public static MqttEquipRedService mqttRideService;
    public static WebSocketDbService webSocketDbService;

    @Resource

    @PostConstruct
    public void init() {
    
        webSocketDbService = this;
    }


}

  ScreenshotLogRepository screenshotLogRepository=
        WebSocketDbService.webSocketDbService.screenshotLogRepository;

        log.info("screenshotLogRepository {}",screenshotLogRepository);
        if(screenshotLogRepository==null){
    
            log.info("screenshotLogRepository  yes null ");
            return;
        }

        log.info("screenshotLog {}",screenshotLog);
        screenshotLog.setCreateTime(new Date());
// ScreenshotLog screenshotLog = jsonObject.toJavaObject(ScreenshotLog.class);
        ScreenshotLog save = screenshotLogRepository.save(screenshotLog);
        log.info("save {}",save);
