org.springframework.core.io.support.ResourcePatternResolver

Strategy interface for resolving a location pattern (for example, an Ant-style path pattern) into Resource objects.

This is an extension to the {@link org.springframework.core.io.ResourceLoader}interface. A passed-in ResourceLoader (for example, an {@link org.springframework.context.ApplicationContext} passed in via{@link org.springframework.context.ResourceLoaderAware} when running in a context)can be checked whether it implements this extended interface too.

{@link PathMatchingResourcePatternResolver} is a standalone implementationthat is usable outside an ApplicationContext, also used by {@link ResourceArrayPropertyEditor} for populating Resource array bean properties.

Can be used with any sort of location pattern (e.g. "/WEB-INF/*-context.xml"): Input patterns have to match the strategy implementation. This interface just specifies the conversion method rather than a specific pattern format.

This interface also suggests a new resource prefix "classpath*:" for all matching resources from the class path. Note that the resource location is expected to be a path without placeholders in this case (e.g. "/beans.xml"); JAR files or classes directories can contain multiple files of the same name. @author Juergen Hoeller @since 1.0.2 @see org.springframework.core.io.Resource @see org.springframework.core.io.ResourceLoader @see org.springframework.context.ApplicationContext @see org.springframework.context.ResourceLoaderAware
