java.beans.PropertyEditorSupport

org.springframework.core.io.support.ResourceArrayPropertyEditor

所有已实现的接口:

PropertyEditor

public class ResourceArrayPropertyEditor
extends PropertyEditorSupport

Editor for Resource arrays, to automatically convert String location patterns (e.g. "file:C:/my*.txt" or "classpath*:myfile.txt") to Resource array properties. Can also translate a collection or array of location patterns into a merged Resource array.

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

Delegates to a ResourcePatternResolver, by default using a PathMatchingResourcePatternResolver.
