Class ExecutorServiceAdapter

java.lang.Object

java.util.concurrent.AbstractExecutorService

org.springframework.core.task.support.ExecutorServiceAdapter

All Implemented Interfaces:

java.util.concurrent.Executor, java.util.concurrent.ExecutorService

public class ExecutorServiceAdapter
extends java.util.concurrent.AbstractExecutorService

Adapter that takes a Spring TaskExecutor) and exposes a full java.util.concurrent.ExecutorService for it.

This is primarily for adapting to client components that communicate via the java.util.concurrent.ExecutorService API. It can also be used as common ground between a local Spring TaskExecutor backend and a JNDI-located ManagedExecutorService in a Java EE 6 environment.

NOTE: This ExecutorService adapter does not support the lifecycle methods in the java.util.concurrent.ExecutorService API ("shutdown()" etc), similar to a server-wide ManagedExecutorService in a Java EE 6 environment. The lifecycle is always up to the backend pool, with this adapter acting as an access-only proxy for that target pool.

3.0
