      Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

      This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

      Specified by:

      protected boolean isUrlRequired()

      The default implementation returns true. This can be overridden in subclasses.

      Check whether the underlying resource that the configured URL points to actually exists.
      Parameters:
      locale - the desired Locale that we're looking for
      Returns:
      true if the resource exists (or is assumed to exist); false if we know that it does not exist
      Throws:
      Exception - if the resource exists but is invalid (for example, could not be parsed)
