[英]Java SockJS Spring client and message size
Using SockJS java client, I am trying to connect to Spring sockjs server and is getting error 1009 for messages (without headers) of ~20Kb. 使用SockJS java客户端,我试图连接到Spring sockjs服务器,并获得错误1009的消息(没有标头)~20Kb。 Javascript library works fine. Javascript库工作正常。
Transport closed with CloseStatus[code=1009, reason=The decoded text message was too big
for the output buffer and the endpoint does not support partial messages] in WebSocketClientSockJsSession

I have couple of config classes on server (I do not know at the moment if I am configuring these things more times than necessary): 我在服务器上有几个配置类(如果我配置这些东西的次数超过必要的话,我现在还不知道):
@Configuration
@EnableWebSocket
public class WebSocketTransportConfig implements WebSocketConfigurer {
// Important web socket setup. If big message is coming through, it may overflow the buffer and this will lead in disconnect.
// All messages that are coming through normally (including snapshots) must be order of magnitude smaller, or connection will be broken
// sometimes
// There is also MaxBinaryMessageSize that we do not employ as we use Stomp, but for completeness it is also set to same values.
// Javadoc http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/socket/adapter/jetty/JettyWebSocketSession.html#setTextMessageSizeLimit-int-
public static final int MAX_TEXT_MESSAGE_SIZE = 2048000; // 2 Megabytes.
public static final int BUFFER_SIZE = MAX_TEXT_MESSAGE_SIZE * 5;
private static final Logger LOGGER = LogManager.getLogger(WebSocketTransportConfig.class);
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
}
@Bean
public DefaultHandshakeHandler handshakeHandler() {
LOGGER.info("Websocket buffer size: " + BUFFER_SIZE + " bytes.");
WebSocketPolicy policy = new WebSocketPolicy(WebSocketBehavior.SERVER);
policy.setMaxTextMessageBufferSize(BUFFER_SIZE);
policy.setMaxTextMessageSize(MAX_TEXT_MESSAGE_SIZE);
policy.setMaxBinaryMessageBufferSize(BUFFER_SIZE);
policy.setMaxBinaryMessageSize(MAX_TEXT_MESSAGE_SIZE);
policy.setInputBufferSize( BUFFER_SIZE);
policy.setIdleTimeout(600000);
return new DefaultHandshakeHandler(
new JettyRequestUpgradeStrategy(new WebSocketServerFactory(policy)));
}
}
and 和
@Configuration
@EnableWebSocketMessageBroker
@EnableScheduling
public class WebSocketBrokerConfig extends WebSocketMessageBrokerConfigurationSupport implements WebSocketMessageBrokerConfigurer {
@Override
public void configureWebSocketTransport(WebSocketTransportRegistration registry) {
// Increase buffers.
// Too little buffers may result in fatal errros when transmitting relatively large messages.
registry.setMessageSizeLimit(WebSocketTransportConfig.MAX_TEXT_MESSAGE_SIZE);
registry.setSendBufferSizeLimit(WebSocketTransportConfig.BUFFER_SIZE);
super.configureWebSocketTransport(registry);
}
}
According to Stomp spring web socket message exceeds size limit that should help but when connecting Java Spring SockJS client, I still get error 1009 (too big message). 根据Stomp spring web socket消息超出大小限制应该有帮助但是在连接Java Spring SockJS客户端时,我仍然得到错误1009(太大的消息)。
I suspect therefore I may have one of two issues: 因此我怀疑我可能有两个问题之一:
How can I increase buffer size on Java SockJS Spring client? 如何在Java SockJS Spring客户端上增加缓冲区大小?
I stumbled with the same problem. 我偶然发现了同样的问题。 It's all about the configuration of the client, not the server. 这都是关于客户端的配置,而不是服务器。 You can create WebSocketContainer instance and configure it. 您可以创建WebSocketContainer实例并对其进行配置。
WebSocketContainer container = ContainerProvider.getWebSocketContainer();
container.setDefaultMaxBinaryMessageBufferSize(your_size);
container.setDefaultMaxTextMessageBufferSize(your_size);
WebSocketClient transport = new StandardWebSocketClient(container);
WebSocketStompClient stompClient = new WebSocketStompClient(transport);
your_size - size in bytes. your_size - 以字节为单位的大小。
If you're doing it like this: 如果你这样做:
SockJsClient sockJsClient = new SockJsClient(transports);
WebSocketStompClient stompClient = new WebSocketStompClient(sockJsClient);
Try: 尝试:
stompClient.setInboundMessageSizeLimit(your_message_size_limit);
