Schedule a task using java

Question

我需要在Web应用程序中使用Java计划任务，更重要的是具有暂停和恢复计划的能力。我知道有TimerTask和Timer，但不确定它们是否具有此暂停选项。有时间调试那段代码。谁能指出一个可以计划，暂停和恢复任务的示例？

Answer 1

I know you've had issues with Qartz but please give it a second look and look at the CronTrigger . And as an example on pausing a task look at this answer: Quartz Java resuming a job excecutes it many times

Answer 2

Have you tried a plain Thread which a boolean flag to to pause it?

Personally I would use ScheduledExecutorService with a flag.

Answer 3

Fundamentally the task is your code. So until your code provides facilities to pause, other frameworks can't really help. The simplest way to provide pausing is expose a public method that just calls sleep on your thread. Now the framework may call in your public method to pause(sleep) your thread.
