如何使用Spring重新加载属性？ [英] How to reload properties with Spring?

问题描述

我正在使用Spring 3的属性文件。
当Spring初始化它的上下文时，它会加载属性文件并将其放在所有带有@Value注释的bean中。

I'm using properties file with Spring 3. When Spring initializes its contex it loads the properties file and puts it in all beans with @Value annotation.

我希望有可能更新文件中的某些属性，并在服务器上公开一个JMX，它会将新属性重新加载到Spring，而无需重新启动服务器，并重新加载其上下文。

I want to have a possibility to update some properties in a file, and expose a JMX on the server that will reload the new properties to Spring - without restarting the server, and reloading its context.

我可以通过使用一些 Spring方法来重新加载属性并将它们填充到所有bean中来实现，或者我应该自己写这样的东西吗？

Can I implement this by using some Spring method to reload properties and populate them to all beans, or should I write something like this by my own?

推荐答案

我建议用 java.util.Properties > Apache Commons Configuration 项目中的PropertiesConfiguration 。它支持自动重新加载，通过检测文件何时更改，或通过JMX触发。

I would suggest replacing the java.util.Properties with a PropertiesConfiguration from the Apache Commons Configuration project. It supports automatic reloading, either by detecting when the file changes, or by triggering through JMX.
