静态方法中调用service接口中的方法

@Component
public class JobTrigger {
    private static Logger logger = LoggerFactory.getLogger(JobTrigger.class);

    @Autowired
    private JobInfoMapper jobInfoMapper;
    public static JobTrigger jobTrigger;

    @PostConstruct //初始化
    public void init() {
        jobTrigger = this;
        jobTrigger.jobInfoMapper = this.jobInfoMapper;
    }

     jobTrigger.jobInfoMapper.updateJobInfoStatus(jobInfo.getId(), "定时任务开始执行");
