javabuffersize单位,JavaSockJSSpring客户端和消息大小

使用SockJS java客户端,我正在尝试连接到Spring sockjs服务器,并且获得了大约20Kb的消息(没有标头)的错误1009. Javascript库工作正常.

Transport closed with CloseStatus[code&＃61;1009, reason&＃61;The decoded text message was too big

for the output buffer and the endpoint does not support partial messages] in WebSocketClientSockJsSession

[id&＃61;&＃39;9fa30eb453e14a8c8612e1064640646a, url&＃61;ws://127.0.0.1:8083/user]

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)&＃xff1a;

&＃64;Configuration

&＃64;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 &＃61; 2048000; // 2 Megabytes.

public static final int BUFFER_SIZE &＃61; MAX_TEXT_MESSAGE_SIZE * 5;

private static final Logger LOGGER &＃61; LogManager.getLogger(WebSocketTransportConfig.class);

&＃64;Override

public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {

}

&＃64;Bean

public DefaultHandshakeHandler handshakeHandler() {

LOGGER.info("Websocket buffer size: " &＃43; BUFFER_SIZE &＃43; " bytes.");

WebSocketPolicy policy &＃61; 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)));

}

}

和

&＃64;Configuration

&＃64;EnableWebSocketMessageBroker

&＃64;EnableScheduling

public class WebSocketBrokerConfig extends WebSocketMessageBrokerConfigurationSupport implements WebSocketMessageBrokerConfigurer {

&＃64;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);

}

}

根据Stomp spring web socket message exceeds size limit应该有帮助,但在连接Java Spring SockJS客户端时,我仍然得到错误1009(太大的消息).

因此我怀疑我可能有以下两个问题之一&＃xff1a;

> Java SockJS客户端也必须配置为RECEIVE更大的消息.

>或者,我仍然在服务器上配置错误.

如何在Java SockJS Spring客户端上增加缓冲区大小&＃xff1f;
