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
