Spring @Async Executor

Question

Is there anyway to be able to specify different Executors for different classes? Seems a bit constricting to have to use one Executor for every async task.

You can have the pooled executor with enough threads.

As of Spring 3.2/3.1.2 you can now qualify your @Async use, much like the use of @Transactional, in the following manner:

@Async("beanNameOrQualifierValue")
public void someOp() {
   ...
}

You can look in the following issues SPR-6847 (3.2) / SPR-9443 (3.1.2) for more details.

You can have several instances of the same task executor type (Pool). But you can not have different Pools.

For example

  <task:executor id="executor" pool-size="10"/>

10 instances of ThreadPoolTaskExecutor

or

   <task:executor id="executorWithPoolSizeRange"
               pool-size="5-25"
               queue-capacity="100"/>

For more details see the spring Reference @see Spring Reference Chapter 25 Task Execution and Scheduling
