Spring动态配置计时器触发时间的实例代码

Spring中添加计时器的时候根据业务需求可能会需要动态处理触发时间;

import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.scheduling.Trigger; import org.springframework.scheduling.TriggerContext; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.scheduling.annotation.SchedulingConfigurer; import org.springframework.scheduling.config.ScheduledTaskRegistrar; import org.springframework.scheduling.support.CronTrigger; import org.springframework.stereotype.Component; import java.util.Date; @Component @EnableScheduling public class SchedulerTest implements SchedulingConfigurer {   private final static Logger logger = LoggerFactory.getLogger(SchedulerTest.class);   public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {     // 注册计时任务到Scheduling接口     scheduledTaskRegistrar.addTriggerTask(new Runnable() {       public void run() {         logger.info("task job is running...");       }     }, new Trigger() {       public Date nextExecutionTime(TriggerContext triggerContext) {         CronTrigger cronTrigger = new CronTrigger("时间表达式");         Date nextExec = cronTrigger.nextExecutionTime(triggerContext);         return nextExec;       }     });   } } 

PS:多个计时任务添加的时候只用都注册到Spring中即可
