这篇文章主要介绍了Spring动态配置计时器触发时间的实例代码,非常不错，具有一定的参考借鉴价值，需要的朋友可以参考下

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; 

									      } 

									    }); 

									  } 

									}
