How to create a function that periodically checks for an event, in a Spring REST API application

Hi

I am working on a Spring based REST API Java web app.

In it, there is a requirement for periodically checking for occurrence of an event, for example - insertion of a new message in a message queue.

How do I create such a function? I want this function to be constantly running-- I should not need to invoke it as such, and it should be constantly running (as long as the app itself is running).

Thanks,
Arvind.

why is the requirement of doing it with REST API?
this should like a scheduler job that can be easily configured using spring batch or spring TaskExecutor.

Also, since you mentioned "monitoring insertion of message in message queue" it sound what you are trying to re-invent is MDB in EJB or Spring MDP.

-P

Then it's not a REST API.
