刷新Spring的属性占位符机制 [英] refresh property placeholder mechanism at Spring

问题描述

我有一个 Spring 上下文xml文件以及一个由 PropertyPlaceholderConfigurer 机制创建的特定bean。
我的问题是：当应用程序正在运行相关的属性文件更改而我不想重启应用程序。我想重新加载相关bean而不重启应用程序。

I have a Spring context xml file and a specific bean into it that created by a PropertyPlaceholderConfigurer mechanism. My problem is: When the application is working related properties file changes and I don't want restart application. I want reload related bean without restart application.

什么是我的目标的最佳解决方案？

What is best solution for my goal?

推荐答案

你可以在github ReloadablePropertiesAnnotation =https://github.com/jamesemorgan/ReloadablePropertiesAnnotation =nofollow> https://github.com/jamesemorgan/ReloadablePropertiesAnnotation

you can have a look at ReloadablePropertiesAnnotation on github https://github.com/jamesemorgan/ReloadablePropertiesAnnotation

这应该只是通过注释您的属性来工作，如

this should just work by annotating your property like

@ReloadableProperty("dynamicProperty.myProperty")
private String myProperty;

你必须添加一些弹簧配置以及github或本博客中的示例< a href =http://www.morgan-design.com/2012/08/reloadable-application-properties-with.html =nofollow> http://www.morgan-design.com/2012/ 08 / reloadable-application-properties-with.html

you'll have to add some spring configuration as well see the example on github or in this blog http://www.morgan-design.com/2012/08/reloadable-application-properties-with.html

在幕后，这是使用Guava的EventBus来更新bean之后的bean的属性已创建。

Under the hood, this is using Guava's EventBus to update the properties of your beans after the bean has been created.
