Package org.activiti.spring

Class SpringAsyncExecutor

java.lang.Object

org.activiti.engine.impl.asyncexecutor.DefaultAsyncJobExecutor

org.activiti.spring.SpringAsyncExecutor

All Implemented Interfaces:

AsyncExecutor

public class SpringAsyncExecutor
extends DefaultAsyncJobExecutor

This is a spring based implementation of the Job Executor using spring abstraction TaskExecutor for performing background task execution.

The idea behind this implementation is to externalize the configuration of the task executor, so it can leverage to Application servers controller thread pools, for example using the commonj API. The use of unmanaged thread in application servers is discouraged by the Java EE spec.
