我正在将spring web-socket实现到我们的spring mvc web应用程序中。但是,当我尝试向端点发送一个非常大的消息时,我遇到了超过大小限制的消息。
我收到以下错误,
message:The 'content-length' header 68718 exceeds the configured message buffer size limit 65536
14:49:11,506 ERROR [org.springframework.web.socket.messaging.StompSubProtocolHandler] (http-localhost/127.0.0.1:8080-4) Failed to parse TextMessage payload=[13684590},..], byteCount=16384, last=true] in session vlsxdeol. Sending STOMP ERROR to client.: org.springframework.messaging.simp.stomp.StompConversionException: The 'content-length' header 68718 exceeds the configured message buffer size limit 65536
at org.springframework.messaging.simp.stomp.BufferingStompDecoder.checkBufferLimits(BufferingStompDecoder.java:148) [spring-messaging-4.1.6.RELEASE.jar:4.1.6.RELEASE]
at org.springframework.messaging.simp.stomp.BufferingStompDecoder.decode(BufferingStompDecoder.java:124) [spring-messaging-4.1.6.RELEASE.jar:4.1.6.RELEASE]
这是我的配置
@MessageMapping("/user/sockettest" )
@SendTo("/topic/sockettestresult")
public String sockAdd(ListId[] listIds) {
..
SecurityContextHolder.getContext().getAuthentication().getPrincipal();
return stringRet;
}
xml配置如下所示
<websocket:simple-broker prefix="/topic"/>
<websocket:message-converters register-defaults="false">
<bean id="mappingJackson2MessageConverter" class="org.springframework.messaging.converter.MappingJackson2MessageConverter">
<property name="objectMapper" ref="objectMapper"></property>
</bean>
</websocket:message-converters>
</websocket:message-broker>
客户端代码如下所示
function versionFiles() {
stompClient.send("/testbrkr/user/sockettest", {}, JSON.stringify(listIds));
}
你能让我知道什么是好的解决方法。
答案:如果你知道什么是最大尺寸限制
<websocket:transport message-size="75536" send-buffer-size="75536"></websocket:transport>
我正在研究如何进行部分消息传递,我会在发现并将其发布后立即在此处发布
答案 0 :(得分:4)
考虑<websocket:transport message-size=""/>
定义的<websocket:message-broker>
选项:
配置传入子协议消息的最大大小。 例如,STOMP消息可以作为多个WebSocket消息被接收 或者在使用SockJS后备选项时发出多个HTTP POST请求。
使用WebSocketMessageBrokerConfigurer.configureWebSocketTransport(WebSocketTransportRegistration)
实施的注释配置和关于此事的setMessageSizeLimit()
可以实现相同的目标。
答案 1 :(得分:1)
List<Transport> transports = new ArrayList<Transport>();
WebSocketContainer container = ContainerProvider.getWebSocketContainer();
container.setDefaultMaxTextMessageBufferSize(512*1024); //FIX
WebSocketClient wsClient = new StandardWebSocketClient(container);
transports.add(new WebSocketTransport(wsClient));
// transports.add(new RestTemplateXhrTransport());
SockJsClient sockJsClient = new SockJsClient(transports);
WebSocketStompClient stompClient = new WebSocketStompClient(sockJsClient);
stompClient.setMessageConverter(new SimpleMessageConverter());
stompClient.setInboundMessageSizeLimit(512 * 1024); //FIX

设置默认值65kb时,我收到了类似的JavaScript错误消息。然后将其设置为随机值,并再次出现诸如
的错误连接被中断
。所以尝试增加时间限制,这对我有用。实际上,当超出限制时,邮件将被发送到数据包/或帧中,并且在接收到来自服务器的响应时会超时。
您可以按以下方式进行调整
@EnableWebSocketMessageBroker
public class AppWebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
----
---
@Override
public void configureWebSocketTransport(WebSocketTransportRegistration registration) {
registration.setMessageSizeLimit(200000); // default : 64 * 1024
registration.setSendTimeLimit(20 * 10000); // default : 10 * 10000
registration.setSendBufferSizeLimit(3* 512 * 1024); // default : 512 * 1024
}

}
答案 3 :(得分:0)
考虑 <websocket:transport message-size=""/>
定义的 <websocket:message-broker>
选项:
配置传入子协议消息的最大大小。例如,当使用 SockJS 回退选项时,STOMP 消息可能会作为多个 WebSocket 消息或多个 HTTP POST 请求接收。
在注解配置中也可以使用
WebSocketMessageBrokerConfigurer.configureWebSocketTransport(WebSocketTransportRegistration)
实施并与 setMessageSizeLimit()
一起讨论此事。
这是对的,但是...如果您使用的是 Spring WebSocket,那么 stomp 消息是
StompSubProtocolHandler
和
@Override
public void afterSessionStarted(WebSocketSession session, MessageChannel outputChannel) {
if (session.getTextMessageSizeLimit() < MINIMUM_WEBSOCKET_MESSAGE_SIZE) {
session.setTextMessageSizeLimit(MINIMUM_WEBSOCKET_MESSAGE_SIZE);
}
this.decoders.put(session.getId(), new BufferingStompDecoder(this.stompDecoder, getMessageSizeLimit()));
}
所以这里的 spring 错误消息大小设置为 websocket:transport message-size 但 WebSocketSession 不是 ... 是 8KB,这个方法会加倍。否作为我们要发送的消息。
我不知道如何解决这个问题;您需要设置 WebSocketSession TextMessageSizeLimit
。也许有人更了解 spring boot factory 知道改变 WebSocketSession textMessageSizeLimit
的 spring 方法。
反正我是用 Aop DelegatingIntroductionInterceptor
在WebSocketMessageBrokerConfigurer
@Override
public void configureWebSocketTransport(WebSocketTransportRegistration registry) {
registry.setMessageSizeLimit(50 * 1024 * 1024); //this not work todo
registry.setSendBufferSizeLimit(50 * 1024 * 1024);
registry.setDecoratorFactories(agentWebSocketHandlerDecoratorFactory());
}
@Bean
public AgentWebSocketHandlerDecoratorFactory agentWebSocketHandlerDecoratorFactory() {
return new AgentWebSocketHandlerDecoratorFactory();
}
AgentWebSocketHandlerDecoratorFactory
会将 WebSocketHandler
代理到自定义 DelegatingIntroductionInterceptor
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.aop.support.AopUtils;
import org.springframework.aop.support.DefaultIntroductionAdvisor;
import org.springframework.aop.target.SingletonTargetSource;
import org.springframework.web.socket.WebSocketHandler;
import org.springframework.web.socket.handler.WebSocketHandlerDecoratorFactory;
public class AgentWebSocketHandlerDecoratorFactory implements WebSocketHandlerDecoratorFactory {
@Override
public WebSocketHandler decorate(WebSocketHandler handler) {
ProxyFactory proxyFactory = new ProxyFactory();
proxyFactory.setTargetClass(AopUtils.getTargetClass(handler));
proxyFactory.setTargetSource(new SingletonTargetSource(handler));
proxyFactory.addAdvisor(new DefaultIntroductionAdvisor(new SubProtocolWebSocketHandlerInterceptor()));
proxyFactory.setOptimize(true);
proxyFactory.setExposeProxy(true);
return (WebSocketHandler) proxyFactory.getProxy();
}
}
和自定义 DefaultIntroductionAdvisor
将拦截 WebSocketHandler afterConnectionEstablished
并设置 WebSocketSession textMessageSizeLimit
import org.aopalliance.intercept.MethodInvocation;
import org.springframework.aop.support.DelegatingIntroductionInterceptor;
import org.springframework.web.socket.WebSocketSession;
public class SubProtocolWebSocketHandlerInterceptor extends DelegatingIntroductionInterceptor {
@Override
protected Object doProceed(MethodInvocation mi) throws Throwable {
if(mi.getMethod().getName().equals("afterConnectionEstablished") ) {
WebSocketSession session = (WebSocketSession) mi.getArguments()[0];
session.setTextMessageSizeLimit(50*1024*1024);
}
return super.doProceed(mi);
}
}
这是经过测试的,将接受大于 16KB 的消息 在呈现的情况下,消息限制大小为 50 * 1024 * 1024
