SpringBoot基于注解：定时执行计划任务

一、@Scheduled 注解

//定时任务类
@Slf4j //日志注解
@Service  
public class ScheduleTaskService {
    private static final Logger log = LoggerFactory.getLogger(ScheduleTaskService.class);

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
    @Scheduled(fixedRate = 5000)
    public void reportCurrentTime(){
        log.info("每五秒执行一次 : {}",dateFormat.format(new Date()));
    }
    @Scheduled(cron = "0 13 15 ? * *")
    public void fixTimeExecute(){
        log.info("指定时间执行 ： {}",dateFormat.format(new Date()));
    }
}

//配置类
@Configuration
@ComponentScan("com.how2java.tmall.scheduletask")
@EnableScheduling  //开启定时任务注解   //2
public class ScheduleTaskConfig {
}
