如何使用Java在一周中的特定日期的特定时间运行任务？

[英]How to run a task on specific days of the week at a certain time in java?

原文 2016-07-08 18:20:01 8 1 java/ scheduled-tasks

I would like my users to be able to choose which days of the week they want to schedule a certain task to run in Java. 我希望我的用户能够选择他们希望在一周中的哪几天计划要在Java中运行的特定任务。 As I understand, the ScheduledExecutorService is only able to run a single execution, or execute at fixed rates. 据我了解，ScheduledExecutorService只能运行一次执行，或以固定的速率执行。 I am able to run a task every day at a specific time, but haven't figured out how to do that for specific days. 我能够每天在特定时间运行一项任务，但是在特定的日子里我还不知道如何去做。
Is there a way to run my task on specific days of the week (eg mon, wed, fri)? 有什么办法可以在一周的特定日期（例如星期一，星期三，星期五）运行我的任务？

Also, I know that there are 3rd party libraries out there that would do well for what I'm asking, such as Quartz, but I'm wondering if there is a way to do this using only Java APIs. 另外，我知道现在有第三方库可以很好地满足我的要求，例如Quartz，但是我想知道是否有一种方法可以仅使用Java API来实现。
