Spring动态创建定时任务，使用@Component(schedulerListener)注解。以下是一个简化后的类定义：

java@Component(schedulerListener)public class SchedulerListener implements ApplicationListener { private static final Logger logger=Logger.getLogger(SchedulerListener.class);

public void onApplicationEvent(ApplicationEvent event) { logger.info(Scheduler listener activated.); }}

spring动态创建定时任务

@Component("schedulerListener") public class SchedulerListener implements ApplicationListener { private static final Logger logger = Logger.getLogger(SchedulerListener.class); private static ThreadPoolTaskScheduler tts = null; @Override public void onApplicationEvent(ContextRefreshedEvent event) { if (tts == null) { tts = new ThreadPoolTaskScheduler(); tts.initialize(); } tts.schedule(new TestRunnable(), new CronTrigger("0 20 0 * * *")); } } public class TestRunnable implements Runnable { @Override public void run() { System.out.println("hello"); } }
