我在嘗試從Spring Websocket服務器發送數據（託管在Tomcat上）時似乎在嘗試發送消息的過程中重置連接。當發送大量的二進制數據時（這裏的示例中的字節數爲5526584字節），錯誤似乎會發生得更多，但我已經看到它發生在文本通道上，並且數據量也較少。然而，發送更多5個左右的MB似乎使其相對一致地崩潰。Spring Websocket服務器在發送大量數據時重置連接
編輯 - 下面的結束編輯塊是服務器端的代碼和錯誤。我現在認爲錯誤是由服務器端造成的。我輸入了一些時間戳，看起來客戶端在服務器拋出錯誤之前收到onClose錯誤。關閉的原因是緩衝區溢出。下面是代碼，我設置WebSocket的容器，並啓動會話：
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));
後來我打印出會議MaxBuffer大小，他們都被設置爲1.28預期。

在我的WebSocket配置者我設置非常寬鬆的緩衝區和超時
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;
}
我還設置了限制SubProtoclHandler
@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("*");
}
最後導致該錯誤的實際發送看起來像這樣
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.");
}
有很多代碼運動件，所以讓我知道如果你需要的任何其他信息。
