With the default ContextLoader * implementation, any context class specified needs to implement * ConfigurableWebApplicationContext. * * <p>Passes a "contextConfigLocation" context-param to the context instance, * parsing it into potentially multiple file paths which can be separated by * any number of commas and spaces, like "applicationContext1.xml, * applicationContext2.xml". If not explicitly specified, the context * implementation is supposed to use a default location (with * XmlWebApplicationContext: "/WEB-INF/applicationContext.xml"). * * <p>Note: In case of multiple config locations, later bean definitions will * override ones defined in earlier loaded files, at least when using one of * Spring's default ApplicationContext implementations. This can be leveraged * to deliberately override certain bean definitions via an extra XML file. * * <p>Above and beyond loading the root application context, this class can * optionally load or obtain and hook up a shared parent context to the root * application context.
