public interface ResourcePatternResolver
Strategy interface for resolving a location pattern (for example, an Ant-style path pattern) into Resource objects.
This is an extension to the ResourceLoader
interface. A passed-in ResourceLoader (for example, an
ApplicationContext
passed in via
ResourceLoaderAware
when running in a context)
can be checked whether it implements this extended interface too.
PathMatchingResourcePatternResolver
is a standalone implementation
that is usable outside an ApplicationContext, also used by
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.

Overlapping resource entries that point to the same physical resource should be avoided, as far as possible. The result should have set semantics.
