## Class ResourceEntityResolver

- java.lang.Object
- - org.springframework.beans.factory.xml.DelegatingEntityResolver
  - - org.springframework.beans.factory.xml.ResourceEntityResolver

- All Implemented Interfaces:
    EntityResolver

      public class ResourceEntityResolver
      extends DelegatingEntityResolver

  EntityResolver implementation that tries to resolve entity references through a `ResourceLoader` (usually, relative to the resource base of an ApplicationContext), if applicable. Extends `DelegatingEntityResolver` to also provide DTD and XSD lookup.

  Allows to use standard XML entities to include XML snippets into an application context definition, for example to split a large XML file into various modules. The include paths can be relative to the application context's resource base as usual, instead of relative to the JVM working directory (the XML parser's default).

  Note: In addition to relative paths, every URL that specifies a file in the current system root, i.e. the JVM working directory, will be interpreted relative to the application context too.
