      public class ClassPathXmlApplicationContext
      extends AbstractXmlApplicationContext

  Standalone XML application context, taking the context definition files from the class path, interpreting plain paths as class path resource names that include the package path (e.g. "mypackage/myresource.txt"). Useful for test harnesses as well as for application contexts embedded within JARs.

  The config location defaults can be overridden via `AbstractRefreshableConfigApplicationContext.getConfigLocations()`, Config locations can either denote concrete files like "/myfiles/context.xml" or Ant-style patterns like "/myfiles/*-context.xml" (see the `AntPathMatcher` javadoc for pattern details).

  Note: In case of multiple config locations, later bean definitions will override ones defined in earlier loaded files. This can be leveraged to deliberately override certain bean definitions via an extra XML file.

  This is a simple, one-stop shop convenience ApplicationContext. Consider using the `GenericApplicationContext` class in combination with an `XmlBeanDefinitionReader` for more flexible context setup.

  - ### Method Detail

    - #### getConfigResources

          protected Resource[] getConfigResources()

      Description copied from class: `AbstractXmlApplicationContext`
      Return an array of Resource objects, referring to the XML bean definition files that this context should be built with.

      The default implementation returns `null`. Subclasses can override this to provide pre-built Resource objects rather than location Strings.

      Overrides:
        `getConfigResources` in class `AbstractXmlApplicationContext`
      Returns:
        an array of Resource objects, or `null` if none
