我在尝试从Spring Websocket服务器发送数据（托管在Tomcat上）时似乎在尝试发送消息的过程中重置连接。当发送大量的二进制数据时（这里的示例中的字节数为5526584字节），错误似乎会发生得更多，但我已经看到它发生在文本通道上，并且数据量也较少。然而，发送更多5个左右的MB似乎使其相对一致地崩溃。Spring Websocket服务器在发送大量数据时重置连接
编辑 - 下面的结束编辑块是服务器端的代码和错误。我现在认为错误是由服务器端造成的。我输入了一些时间戳，看起来客户端在服务器抛出错误之前收到onClose错误。关闭的原因是缓冲区溢出。下面是代码，我设置WebSocket的容器，并启动会话：
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));
后来我打印出会议MaxBuffer大小，他们都被设置为1.28预期。

在我的WebSocket配置者我设置非常宽松的缓冲区和超时
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;
}
我还设置了限制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("*");
}
最后导致该错误的实际发送看起来像这样
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.");
}
有很多代码运动件，所以让我知道如果你需要的任何其他信息。
