EJB @Asynchronous不在同一类工作 [英] EJB @Asynchronous does not work in same class

问题描述

我有以下情况：

我希望的methodB被执行10次并联。但它只能发生在的methodB是从另一个bean调用。

I wish the "methodB" was executed 10 times paralleling. But it only happening when the "methodB" is called from another bean.

为什么标注@Asynchronous时，该方法是从同一类的另一种方法叫做不起作用？

Why the annotation "@Asynchronous" does not work when the method is called from another method in the same class?

感谢。

推荐答案

它仅适用于方法通过一个客户端代理调用，例如 @Local 或 @Remote 接口。这是在EJB 3.1规范（第4.5节 - 4.5.1）描述：

It only works for methods call via a client proxy, for example a @Local or @Remote interface. This is described in the EJB 3.1 specs (section 4.5 - 4.5.1):

一个会话bean可以公开使用异步方法客户端调用语义

A session bean can expose methods with asynchronous client invocation semantics

...

该@Asynchronous注解用于指定其中一个营业方法是异步的。

The @Asynchronous annotation is used to designate which business methods are asynchronous.

...

异步方法调用的语义只适用于无接口，本地业务，远程业务的客户意见

Asynchronous method invocation semantics only apply to the no-interface, Local business, and Remote business client views.
