java工具类调用service层,mapper层

import com.xxxx.mapper.AlarmLogMapper;
import com.xxxx.mapper.DefenceMapper;;
import com.xxxx.model.AlarmLog;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
 
//命令解码工具类
@Slf4j
@Component
public class TestUtil {    //返回头部
 
    @Autowired
    AlarmLogMapper alarmLogMapper;
    @Autowired
    DefenceMapper defenceMapper;
    public static TestUtil testUtil;
    static AlarmLog alarmLog = new AlarmLog();
    @PostConstruct
    public void init() {
        testUtil = this;
    }
 
    //报警日志记录
    public static void addAlarmLog() {
        alarmLog.setNickname("报警主机");
        alarmLog.setUserId(9999);
        testUtil.alarmLogMapper.insert(alarmLog);
