    • handleClientMessageProcessingError

      @Nullable public Message<byte[]> handleClientMessageProcessingError(@Nullable Message<byte[]> clientMessage, Throwable ex)
      Description copied from interface: SubProtocolErrorHandler
      Handle errors thrown while processing client messages providing an opportunity to prepare the error message or to prevent one from being sent.

      Note that the STOMP protocol requires a server to close the connection after sending an ERROR frame. To prevent an ERROR frame from being sent, a handler could return null and send a notification message through the broker instead, e.g. via a user destination.

      Specified by:
      handleClientMessageProcessingError in interface SubProtocolErrorHandler<byte[]>
      Parameters:
      clientMessage - the client message related to the error, possibly null if error occurred while parsing a WebSocket message
      ex - the cause for the error, never null
      Returns:
      the error message to send to the client, or null in which case no message will be sent.

    • handleErrorMessageToClient

      @Nullable public Message<byte[]> handleErrorMessageToClient(Message<byte[]> errorMessage)
      Description copied from interface: SubProtocolErrorHandler
      Handle errors sent from the server side to clients, e.g. errors from the "broke relay" because connectivity failed or the external broker sent an error message, etc.
      Specified by:
      handleErrorMessageToClient in interface SubProtocolErrorHandler<byte[]>
      Parameters:
      errorMessage - the error message, never null
      Returns:
      the error message to send to the client, or null in which case no message will be sent.
