接口 SubProtocolErrorHandler<P>

方法详细资料

• handleClientMessageProcessingError

  Message<P> handleClientMessageProcessingError​(Message<P> clientMessage,
                                                Throwable ex)

  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.

  参数:

  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

  返回:

  the error message to send to the client, or null in which case no message will be sent.

• handleErrorMessageToClient

  Message<P> handleErrorMessageToClient​(Message<P> errorMessage)

  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.

  参数:

  errorMessage - the error message, never null

  返回:

  the error message to send to the client, or null in which case no message will be sent.
