      org.springframework.core.io.ResourceEditor

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 system properties: e.g. ${user.dir}.

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