Stomp over websocket：发送缓冲区大小超过了允许的限制

Question

在客户端我使用 Stomp 进行 websocket 连接和服务器端我使用 Spring 4 它客户端我做了配置

var socket = new SockJS(urlBase + "/" + contextroot+'/hello');
stompClient = Stomp.over(socket);

以下代码每 2 秒执行一次以向服务器发送数据

stompClient.send('/app/sendRequest/'+indexVal, {}, 
JSON.stringify({index : simIndex}));

服务器响应下面的队列

stompClient.subscribe('/queue/response', processResponseObj);

在服务器端配置完成

<websocket:message-broker application-destination-prefix="/app">
   <!--<websocket:transport send-timeout="15000" message-size="1051648" send-buffer-size="1051648"/> -->
   <websocket:stomp-endpoint path="/hello">
       <websocket:sockjs />
   </websocket:stomp-endpoint>
   <websocket:stomp-broker-relay prefix="/topic, /queue"  />

    <websocket:message-converters>
        <beans:bean class="org.springframework.messaging.converter.MappingJackson2MessageConverter">
        <beans:property name="objectMapper" ref="objectMapper" />
       </beans:bean>
    </websocket:message-converters>

    </websocket:message-broker>

消息在服务器端响应

 messagingTemplate.convertAndSend("/queue/response",obj);

几秒钟后我收到错误消息

我也尝试增加缓冲区大小，但一段时间后它给出了同样的异常。一旦达到缓冲区大小。

我认为 websocket 会话缓冲区在消息传递后不会释放。

是否有任何设置要求？ 我错过了任何配置吗？

Answer 1

添加解决

 public void configureWebSocketTransport(WebSocketTransportRegistration registration) {
registration.setMessageSizeLimit(102400* 1024); 
}

Answer 2

尝试在服务器端配置 web socket。 在 WebSocketConfig 类中是这样的：

 public void configureWebSocketTransport(WebSocketTransportRegistration registration) {
    registration.setMessageSizeLimit(500 * 1024);
    registration.setSendBufferSizeLimit(1024 * 1024);
    registration.setSendTimeLimit(20000);
}
