Is there a way to reload a specific ResourceBundle?

I have a custom database-backed ResourceBundle that needs to be reloaded sometimes. I do not want to use ResourceBundle.clearCache() because it reloads all the bundles.

Is it possible to reload just one bundle?

Solution

  • What you want to do is part of the Java API since 1.6. Start by getting the handle to the bundle you want to reload:

    ResourceBundle bundle = ResourceBundle.getBundle("MyResources", new Locale("fr", "CH"),
                        ResourceBundle.Control.getControl(FORMAT_PROPERTIES));

    You can set the time to live for the bundle and allow the loader to reload it for you. You can read all about this in the Java API docs.
