spring 使用注解来调度定时任务

@Configuration
@ComponentScan(basePackages = "com.test.indexer.service")
public class AppConfig {
}

/**
 * 定时任务
 */
@Component
public class ScheduledTasks {
    
    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

    @Scheduled(fixedRate = 5000)
    public void reportCurrentTime() {
        System.out.println("------------------The time now is " + dateFormat.format(new Date()));
    }
}

@Configuration
@EnableAsync
@EnableScheduling
public class App {
// todo
}
