Examples of org.springframework.web.socket.server.HandshakeFailureException

org.springframework.web.socket.server.HandshakeFailureException
Thrown when handshake processing failed to complete due to an internal, unrecoverable error. This implies a server error (HTTP status code 500) as opposed to a failure in the handshake negotiation.
By contrast, when handshake negotiation fails, the response status code will be 200 and the response headers and body will have been updated to reflect the cause for the failure. A {@link HandshakeHandler} implementation will have protected methods tocustomize updates to the response in those cases. @author Rossen Stoyanchev @since 4.0
