一旦Spring应用程序成功部署，运行代码 [英] Run code once Spring app is succesfully deployed

问题描述

在Spring应用程序中有没有办法知道初始化完成时间？我的应用程序部署后，我必须运行一些代码，我正在搜索一些类似ServletContextListener或 Spring built-在事件。任何想法？

Is there a way in a Spring app to know when the initialization has finished? I have to run some code once my app is deployed and I'm searching something like ServletContextListener or Spring built-in events. Any idea?

推荐答案

根据您对我的评论的回应，我将回应您可以处理初始化的Spring的多项内容bean。

Based on your response to my comment I will respond with the multiple things you can do to process an initialized Spring bean.

1. 您可以使用 BeanPostProcessor 。它有两种方法被视为回调，我相信 postProcessAfterInitialization 是你会感兴趣的。 BeanPostProcessor 的东西是它们在 ApplicationContext 中的每个bean运行，所以你一定要找到你有兴趣应用这个处理的bean。要使用 BeanPostProcessor ，您只需将其定义为 ApplicationContext 的一部分。


2. 实施 InitializingBean 界面。它定义了一个单一的方法 ApplicationContext 调用的relPropertiesSet 之后的rel =noreferrer> 。这比1号有一个优点，因为它可以以bean为基础应用（不适用于 ApplicationContext 中的所有bean）。


3. 利用 @PostContuct 注释方法。该注释告诉 ApplicationContext ，该方法应该在bean初始化之后运行。这样做与第2号类似，因为它是以豆为单位执行的。

1. You can utilize a BeanPostProcessor. It has two methods that are treated as callbacks, and I believe that postProcessAfterInitialization is the one that you would be interested in. The thing with BeanPostProcessor's is that they are run for each bean in the ApplicationContext, so you will want to be sure to look for only the bean(s) that you are interested in applying this processing to. To use a BeanPostProcessor, you simply define it as a part of your ApplicationContext.
2. Implement the InitializingBean interface. It defines a single method afterPropertiesSet which is invoked by the ApplicationContext. This has an advantage over number 1, as it can be applied on a bean by bean basis (doesn't apply to all beans in ApplicationContext).
3. Utilize the @PostContstuct annotation on a method. This annotation tells the ApplicationContext that this method should be run after the bean has been initialized. This acts similarly to number 2, in that it is performed on a bean by bean basis.
