Question

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.

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.

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?

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.
