Is it possible to send binary data with STOMP over WebSockets using Spring-WebSockets?

Question

I am able to send and receive JSON with STOMP over WebSockets following spring documentation. However performance is poor at large high rates, so I wish to profile the use o

Answer 1

It seems that org.springframework.web.socket.TextMessage is always used within org.springframework.web.socket.messaging.StompSubProtocolHandler rather than org.springframework.web.socket.BinaryMessage. I've raised a feature request for this SPR-12301 which has been accepted.

message = MessageBuilder.withPayload(message.getPayload()).setHeaders(headers).build();
byte[] bytes = this.stompEncoder.encode((Message) message);

synchronized(session) {
    session.sendMessage(new TextMessage(new String(bytes, UTF8_CHARSET)));
}

Update

• SPR-12301 was delivered in 4.1.2 but only adds support for receiving binary messages
• Raised SPR-12475 for sending of binary messages
