This implementation delegates to this context's ResourceLoader if set, falling back to the default superclass behavior else.

Usage

From source file:org.openadaptor.spring.SpringAdaptor.java

/**
 * Configure the default PropertyPlaceholderConfigurer.
 * <br>/*from ww  w . j  a v  a 2s.  c  o m*/
 * Unless suppressAutomaticPropsConfig is set true by supplying -noprops as a command line arg then
 * this method creates and installs a PropertyPlaceholderConfigurer which allows access to System Properties
 * and optionally add all -props defined urls as property resource locations.<br>
 * With one exception all urls are passed through to the context in order to locate the resource. The exception
 * is a url that is not prefixed with a protocol is assumed to be a file and arbitratily prefixed with "file:"<br>
 * NB the arbitrary name given to the generated PropertyPlaceholderConfigurer is "openadaptorAutoGeneratedSystemPropertyConfigurer".
 *
 * @param context Spring Context being used.
 * @param propsUrlList Supplied List or Property URLS.
