Interface ResourcePatternResolver

All Known Implementing Classes:

PathMatchingResourcePatternResolver

public interface ResourcePatternResolver

Strategy interface for resolving a location pattern into Resource objects.

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.

CLASSPATH_URL_PREFIX

public static final java.lang.String CLASSPATH_URL_PREFIX

Pseudo URL prefix for all matching resources from the class path. This differs from ResourceLoader's classpath URL prefix in that it retrieves all matching resources for a given name (e.g. "/beans.xml"), for example in the root of all deployed JAR files.
