Spring Websocket服务器在发送大量数据时重置连接

    我遇到了这样的问题:当尝试从Spring Websocket服务器(托管在Tomcat上)发送数据时,似乎在尝试发送消息的过程中重置了连接。在发送大量二进制数据(本例中为5526584字节)时,错误似乎发生得更多,但我已经看到它发生在文本通道上,并且数据也更少。然而,发送超过5 MB左右的数据似乎会相对一致地导致崩溃。 

    WebSocketContainer c = ContainerProvider.getWebSocketContainer();


    c.setDefaultMaxTextMessageBufferSize(128000000); // Should we enable these on the client?
    c.setDefaultMaxBinaryMessageBufferSize(128000000); // Should we enable these on the client?
    c.setDefaultMaxSessionIdleTimeout(500000);
    c.setAsyncSendTimeout(50000);
    session = c.connectToServer(this, config, new URI("wss://" + SERVER + ":" + PORT + WEBSOCKETENDPOINT));

    我稍后打印出会话MaxBuffer大小,它们都按预期设置为128000000。

    public ServletServerContainerFactoryBean createWebSocketContainer() {

ServletServerContainerFactoryBean container = new 
ServletServerContainerFactoryBean();
container.setMaxTextMessageBufferSize(128000000); //128 MB
container.setMaxBinaryMessageBufferSize(128000000); //128 MB
container.setMaxSessionIdleTimeout(500000);
container.setAsyncSendTimeout(50000);

return container;
}

    我还为subtoclhandler设置了限制 

    @Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {


    SubProtocolWebSocketHandler test = new SubProtocolWebSocketHandler(new DirectChannel(), clientInboundChannel());
    test.setSendBufferSizeLimit(128000000);
    test.setSendTimeLimit(50000);
    for(SubProtocolHandler handler : handlers)
    {
        test.addProtocolHandler(handler);
    }


    MyWebSocketHandshakeHandler handshaker = new MyWebSocketHandshakeHandler();


    handshaker.setSupportedProtocols(test.getSubProtocols().toArray(new String[0]));
    registry.addHandler(test, websocketEndpoint).setHandshakeHandler(handshaker)
            .addInterceptors(new HttpSessionHandshakeInterceptor()).setAllowedOrigins("*");

}

    最后,导致错误的实际发送如下所示 

    byte[] tbuf = null;
        try {
            tbuf = jsonMapper.writeValueAsBytes(demoLists.get(stage));
            ByteBuffer buf = ByteBuffer.allocate(tbuf.length);
            buf.put(tbuf);
            buf.flip();
            WebSocketMessage<ByteBuffer> ret = new BinaryMessage(buf);
            System.out.println("Binary limit: " + session.getBinaryMessageSizeLimit());
            System.out.println("Sending bytes: " + ret.getPayloadLength());
            if(session.isOpen()) {
                session.sendMessage(ret);

            } else {
                System.out.println("Session is closed already.");
            }

    代码中有很多移动部分,因此如果您需要任何其他信息,请告诉我。

    在做了更多的研究之后,我发现了这个问题 Incoming buffer size cannot be set to Tyrus client 这让我想到 https://tyrus-project.github.io/documentation/1.12/user-guide.html#d0e1197 

    ClientManager client = ClientManager.createClient(c); 
    client.getProperties().put("org.glassfish.tyrus.incomingBufferSize", 128000000); 
    session = client.connectToServer(this, config, new URI("wss://" + SERVER + ":" + PORT + WEBSOCKETENDPOINT));
