All Implemented Interfaces:

PropertyEditor

public class ResourceEditor
extends PropertyEditorSupport

Editor for Resource descriptors, to automatically convert String locations e.g. file:C:/myfile.txt or classpath:myfile.txt to Resource properties instead of using a String location property.

The path may contain ${...} placeholders, to be resolved as Environment properties: e.g. ${user.dir}. Unresolvable placeholders are ignored by default.

Delegates to a ResourceLoader to do the heavy lifting, by default using a DefaultResourceLoader.
