Class ResourceManager

java.lang.Object
  net.lessy.util.resource.ResourceManager

All Implemented Interfaces:

MessageResolver

public class ResourceManager
extends Object
implements MessageResolver

Convenient Manager around a resource bundle. This class is a pseudo singleton. You can create more then one instance but only the last created instance can be retrieved with the getInstance-Method.

If you have only one bundle, then call the constructor once and pass the bundlename to it. From there you can always get a reference to the manager with the static getInstance-Method.

The manager can be configured through Spring by just adding it as a bean and configuring the bundlename as a constructor parameter.
