如何在服务器上每x分钟运行一次算法？

Question

I've created a clustering algorithm in Java that reads from a collection in a Mongo database, makes its computations and then writes to a new collection in the same database. Now, I need this algorithm to run every 30 minutes in the server. What could I use to do so?

Answer 1

你可以使用石英调度程序每30分钟安排一次算法，你可以在这里找到一个很好的石英调度程序教程。

Answer 2

If you're using JavaEE, you could use the @Schedule annotation.

Take a look at the API here . It saves you from using a dependency in your project.

Update:

If you're using JavaSE, maybe a Timer can help you.
