@Schedule 如何解决定时任务推迟执行

// 启用定时任务
@EnableScheduling 
@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

@Component
public class Task {
    Logger logger = LoggerFactory.getLogger(Task.class);
	// 每五秒执行一次
    @Scheduled(cron = "0/5 * * * * ?")
    public void taskTestA() throws InterruptedException {
        logger.info("A:");
        TimeUnit.SECONDS.sleep(20);
    }
  
    // 每十秒执行一次
    @Scheduled(cron = "0/10 * * * * ?")
    public void taskTestB() {
        logger.info("B:");
    }
}

// 若不设置默认为单线程，这里设置使用线程池，大小为4
spring：
  task:
    scheduling:
      pool:
        size: 4

// 启用异步，动态创建线程
@EnableAsync
