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
