Running a job/asynchronous task with spring 3 at frequency that can be altered by the user

Question

I can set a task to run using scheduled annotation with a fixed frequency. However I want the frequency to vary depending on user input.

What is the best way to accomplish this ?

Answer 1

I suggest using TaskScheduler directly without @Scheduled annotations. You can schedule jobs using user input and have better control over task execution.

Declare you scheduler in spring context:

<task:scheduler id="taskScheduler" pool-size="5" />

And inject it into your service beans using @Autowire annotation

@Autowire
private TaskScheduler taskScheduler;
