How to use Spring's ThreadPoolExecutorFactoryBean factory bean
提问by tmbrggmn
I would like to be able to inject an ExecutorServiceinstance into my Spring services, and the Spring API suggest using ThreadPoolExecutorFactoryBeanfor this purpose. Very simple question; how the hell do I use the ThreadPoolExecutorFactoryBeanto create an ExecutorServicethat I can wire into my other services?
我希望能够将一个ExecutorService实例注入到我的 Spring 服务中，Spring API 建议ThreadPoolExecutorFactoryBean为此目的使用。很简单的问题；我到底如何使用ThreadPoolExecutorFactoryBean来创建一个ExecutorService我可以连接到我的其他服务的？
I feel like a complete idiot for asking his question, but I can't seem to get this figured out.
问他的问题我觉得自己是个彻头彻尾的白痴，但我似乎无法弄清楚这一点。

First off, you need to learn what a FactoryBeanis - read section 3.8.3of the spring docs.
首先，您需要了解什么是 a FactoryBean- 阅读spring 文档的第 3.8.3 节。
Then, you read the Javadocfor ThreadPoolExecutorFactoryBeanand understand what it does.
然后，你读的Javadoc的ThreadPoolExecutorFactoryBean，并了解它做什么。
Next, you configure a ThreadPoolExecutorFactoryBeanin your context. This will create an ExecutorService(since it's a FactoryBean, see above), which you can inject into your bean.
接下来，ThreadPoolExecutorFactoryBean在您的上下文中配置 a 。这将创建一个ExecutorService（因为它是 a FactoryBean，请参见上文），您可以将其注入到您的 bean 中。

To expand on skaffman's answer, here's a short and sweet example of what one needs to do:
为了扩展skaffman 的回答，这里有一个简短而甜蜜的例子，说明了一个人需要做什么：
<bean id="classNeedingExecutor" class="foo.Bar">
<property name="executor" ref="threadExecutor" />
</bean>
<bean id="threadExecutor"
class="org.springframework.scheduling.concurrent.ThreadPoolExecutorFactoryBean">
<property name="corePoolSize" value="1" />
<property name="maxPoolSize" value="1" />
</bean>
Again, see the JavaDocsfor an explanation of the other properties that can be set to configure the ExecutorService.
同样，请参阅JavaDocs以了解可设置以配置ExecutorService.

You may consider using @Async if you're using spring 3, http://blog.espenberntsen.net/2010/03/08/spring-asynchronous-support/.
如果您使用的是 spring 3，您可以考虑使用 @Async，http://blog.espenberntsen.net/2010/03/08/spring-asynchronous-support/ 。
