我正在尝试使用
在我的应用程序中，
Spring Websocket日志;
以及浏览器日志；
你可以清楚地看到，在这之后有10秒钟的沉默。
我使用以下配置来配置我的WebSocketBroker：
Spring Websocket与Sockjs和STOMPjs。根据Spring Websocket文档，在/info请求之后，客户端会向/websocket发送协议升级请求。客户端应返回HTTP状态码 101。在我的应用程序中，
Spring Websocket如预期地返回Http 101，但只有10秒钟的时间限制。Spring Websocket日志;

我使用以下配置来配置我的WebSocketBroker：
2018-04-12 14:27:52.669 TRACE 24509 --- [io-8080-exec-10] o.s.w.s.s.s.DefaultHandshakeHandler : 升级到WebSocket，子协议=null，扩展=[]
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry
.addEndpoint("/api/v3/websocket")
.setHandshakeHandler(new DefaultHandshakeHandler(new TomcatRequestUpgradeStrategy()))
.setAllowedOrigins("*")
.withSockJS()
.setClientLibraryUrl("https://cdnjs.cloudflare.com/ajax/libs/sockjs-client/1.1.4/sockjs.min.js");
}
问题： 我应该关注哪些方面来解决这个延迟问题？我尝试了不同的电脑、不同的浏览器等，但总是会出现约10秒钟的延迟。
setHandshakeHandler()这一行代码真是救了我一命！在 Liberty 上设置安全的 WebSockets (WSS) 时，我遇到了很奇怪的问题，而这一行代码解决了我一个星期的测试和无进展的困境。非常感谢您！ 在我的情况下，我需要将其更改为setHandshakeHandler(new DefaultHandshakeHandler(new WebSphereRequestUpgradeStrategy()))。 - Stan
