Spring Websocket STOMP:发送 RECEIPT 帧 [英] Spring Websocket STOMP: send RECEIPT frames

问题描述

我有一个基于 Spring 的 Websocket-stomp 服务器及其 SimpleBroker 实现(不使用外部代理).

I have a Websocket-stomp server based on Spring and its SimpleBroker implementation (not utilizing an external broker).

我想启用 STOMP RECEIPT 消息.

I would like to enable STOMP RECEIPT messages.

如何配置我的代码以自动发送这些?

How I could configure my code to send these automatically?

推荐答案

在 STOMP 协议的 Spring 集成测试中，我们有以下代码:

In Spring Integration test for the STOMP protocol we have this code:

    //SimpleBrokerMessageHandler doesn't support RECEIPT frame, hence we emulate it this way
    @Bean
    public ApplicationListener<SessionSubscribeEvent> webSocketEventListener(
            final AbstractSubscribableChannel clientOutboundChannel) {
        return event -> {
            Message<byte[]> message = event.getMessage();
            StompHeaderAccessor stompHeaderAccessor = StompHeaderAccessor.wrap(message);
            if (stompHeaderAccessor.getReceipt() != null) {
                stompHeaderAccessor.setHeader("stompCommand", StompCommand.RECEIPT);
                stompHeaderAccessor.setReceiptId(stompHeaderAccessor.getReceipt());
                clientOutboundChannel.send(
                        MessageBuilder.createMessage(new byte[0], stompHeaderAccessor.getMessageHeaders()));
            }
        };
    }
