Spring的任务定时调度方法的研究比较

在Web应用中,经常需要将某个工作安排在某个特定时间点去做。Spring提供了丰富多样的任务执行调度,包括使用JDK Timer、使用SchedulingTaskExecutor接口的实现类、使用Quartz、使用TaskScheduler以及采用@Scheduled注解等多种形式。研究得出,JDK Timer仅支持简单的间隔定时执行;SchedulingTaskExecutor接口的实现类提供了并发任务的各类执行方式;Quartz和TaskScheduler支持基于Cron表达式的定时调度,后者还可通过@Scheduled注解定义任务定时。

Research and Comparison of Spring Task Schedule Methods

Some tasks in web applications are often arranged in a special time.Spring provides various ways for task scheduling such as using by JDK Timer,by the concrete class which implements SchedulingTaskExecutor interface,by Quartz,by TaskScheduler,and by the annotation named @Scheduled.The paper studies and achieves that JDK Timer only supports simple Interval timing task:the concrete class of SchedulingTaskExecutor provides many kinds of execute mode for concurrent task.In additon,Quartz and TaskScheduler support time scheduling with Cron expression,and the latter also supports the definition of @Scheduled annotation.
