How can I use spring to fire off an asynchronous batch task?

Question

Basically I would like to do some multithreading in my spring java program and I don't know how to use my servers spring resources to create a new thread.

I looked at Any good Spring threading with a TaskExecutor examples? but I couldn't figure out where the original TaskExecutor came from, like how would I pass that into the class?

Also is TaskExecutor the best thing to use for just creating another thread in my program?

Answer 1

The TaskExecutor is defined in the xml spring beans definition and passed as constructor's argument to the utility class.

 <constructor-arg type="org.springframework.core.task.TaskExecutor" ref="taskExecutor" />

If you have the choice, you should definitely work with TaskExecutor and Threadpool instead of managing your thread the old way.

Answer 2

The post that you mention gives a good example of what you want to do. taskExecutor is injected via the constructor. Checkout the spring beans configuration given in that post. I believe it is a good practice to use TaskExecutor.
