 @Nullable
 String selectedProtocol,
 List<WebSocketExtension> selectedExtensions,
 @Nullable
 Principal user,
 WebSocketHandler handler,

             throws HandshakeFailureException

Description copied from interface: RequestUpgradeStrategy

Perform runtime specific steps to complete the upgrade. Invoked after successful negotiation of the handshake request.

Specified by:

upgrade in interface RequestUpgradeStrategy

Parameters:

request - the current request

response - the current response

selectedProtocol - the selected sub-protocol, if any

selectedExtensions - the selected WebSocket protocol extensions

user - the user to associate with the WebSocket session

handler - the handler for WebSocket messages

attributes - handshake request specific attributes to be set on the WebSocket session via HandshakeInterceptor and thus made available to the WebSocketHandler

Throws:

HandshakeFailureException - thrown when handshake processing failed to complete due to an internal, unrecoverable error, i.e. a server error as opposed to a failure to successfully negotiate the requirements of the handshake request.
