任何其他指针？

推荐答案

这里有石英的一些优点

1. 如果使用基于操作系统的cron，jvm会上下移动，任何状态都会丢失。 / li>
   
2. 它是可移植的（可以在没有cron的Win操作系统上运行）


3. 您可以在quartz里安排多个线程


4. 我们在tomcat中运行我们的调度程序，因此我们可以通过管理网页管理和查看应用程序的状态。在我们的应用程序中，我们使用jamon来监视我们的进程的状态。它可以回答这样的事情...哪些进程当前正在运行？他们上次什么时候跑？他们需要多长时间？ cron不允许这样做。


5. 您的代码将更容易移植。在不同的操作系统中进行不同的调度。

1. If you use an OS based cron the jvm would go up and down and any state would be lost.
2. it is portable (can run on Win OS where no cron available)
3. You can schedule multiple threads within quartz
4. We run our scheduler in tomcat and so we can manage and see the state of the app via admin web pages. In our app we use jamon to monitor the state of our processes. It can answer such things as... Which processes are currently running? When did they last run? How long did they take? etc. cron would not allow this.
5. Your code would be more portable. Scheduling is done differently in different OS's.

大概石英应该被看作是代替cron的替代品。

Probably quartz should be seen more as a replacement for launching new threads than as a replacement of cron.
