  • Method Details

    • setUrl

    • afterPropertiesSet

      public void afterPropertiesSet() throws Exception
      Description copied from interface: InitializingBean
      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:
      afterPropertiesSet in interface InitializingBean
      Throws:
      Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason

    • isUrlRequired

      protected boolean isUrlRequired()
      Return whether the 'url' property is required.

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

    • checkResource

      public boolean checkResource(Locale locale) throws Exception
      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)
