Easier way to specify a java file to be spring config file

Right now, the only way to specify that a Java file is really a spring config file is through the project properties page. Suggestions for improvement:

1. Menu item under spring tools to specify a java file to be config
2. Keybinding for the same
3. Auto-discovery. There should be a spring tools command to auto-discover java config files. (and maybe xml config files as well). These kinds of files should be fairly easy to determine. And once the operation is done, a dialog should popup and give the user an opportunity to exclude anything found.
