Imports
java.beans.PropertyEditorSupport, java.io.IOException, org.springframework.core.io.Resource, .ResourceEditor, org.springframework.core.io.support.EncodedResource, org.springframework.lang.Nullable, org.springframework.util.Assert
One-way PropertyEditor which can convert from a text String to a java.io.Reader, interpreting the given String as a Spring resource location (e.g. a URL String).

Supports Spring-style URL notation: any fully qualified standard URL ("file:", "http:", etc.) and Spring's special "classpath:" pseudo-URL.

Note that such readers usually do not get closed by Spring itself!
