通过WebSocket发送Stomp消息：发送缓冲区大小超过允许的限制。

Question

通过WebSocket发送Stomp消息：发送缓冲区大小超过允许的限制。

10

在客户端，我使用Stomp进行WebSocket连接，在服务器端，我使用Spring 4。在客户端，我进行了如下配置：

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

以下代码每2秒执行一次，用于将数据发送到服务器。

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

服务器响应以下队列

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

服务器端配置完成如下：

<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>

服务器已响应消息

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

几秒后我收到了错误信息

我尝试增加缓冲区大小，但是在一段时间后它会产生相同的异常，一旦缓冲区大小到达。

我认为WebSocket会话缓冲区在消息传递后没有被释放。

是否需要设置相同的内容？我是否错过了任何配置？

你解决了这个问题吗？我也遇到了同样的问题。 - Brian Sternari

通过添加 registration.setMessageSizeLimit(102400* 1024); 解决。 - Deepak Mule

尝试在服务器端配置Web套接字。类似于WebSocketConfig类中的以下内容：

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