春天@Configuration（非XML配置）的注解驱动的任务 [英] Spring @Configuration (non-xml configuration) for annotation-driven tasks

问题描述

任何人都可以解释如何做到实现使用@Scheduled注解没有任何XML配置一个任务的基本配置？所有的例子，我可以找到使用至少一个最小的XML配置。例如：

Can anyone explain how to do achieve a basic configuration of a task using the @Scheduled annotation without any XML configuration? All the examples I can find use at least a minimal XML configuration. For example:

本采用了典型的：

  <context:component-scan base-package="org/springframework/samples/task/basic/annotation"/> 
  <task:annotation-driven/>

所以我只是用了一堆@Bean批注的@Configuration注释。他们都在实例启动时，但一个具有@Scheduled不运行。我一直在使用XML配置时使用的标注成功地在过去，但从来没有只注释。

So I'm just using a @Configuration annotation with a bunch of @Bean annotations. They are all instantiated at startup but the one with the @Scheduled does not run. I've used that annotation successfully in the past when using XML configuration, but never with annotations only.

推荐答案

的＆LT;任务：注解驱动/＆GT; 标注结束声明ScheduledAnnotationBeanPostProcessor阅读@Scheduled注释在code。看这里：<一href=\"http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/scheduling/annotation/ScheduledAnnotationBeanPostProcessor.html\" rel=\"nofollow\">http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/scheduling/annotation/ScheduledAnnotationBeanPostProcessor.html.

The <task:annotation-driven /> annotation ends up declaring a ScheduledAnnotationBeanPostProcessor to read the @Scheduled annotations in your code. See here: http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/scheduling/annotation/ScheduledAnnotationBeanPostProcessor.html.

这需要照顾的＆LT的;任务：注解驱动/＆GT; 行。要获得组件扫描，您需要使用AnnotationConfigApplicationContext。不知道是否/如何与Web容器的作品虽然。

That takes care of the <task:annotation-driven /> line. To get the component scanning you'll need to use AnnotationConfigApplicationContext. Not sure if/how that works with a web container though.
