类 AsyncResult<V>

java.lang.Object

org.springframework.scheduling.annotation.AsyncResult<V>

所有已实现的接口:

Future<V>, org.springframework.util.concurrent.ListenableFuture<V>

public class AsyncResult<V>
extends Object
implements org.springframework.util.concurrent.ListenableFuture<V>

A pass-through Future handle that can be used for method signatures which are declared with a Future return type for asynchronous execution.

As of Spring 4.1, this class implements ListenableFuture, not just plain Future, along with the corresponding support in @Async processing.

As of Spring 4.2, this class also supports passing execution exceptions back to the caller.

从以下版本开始:

3.0
