Question

使用 Vaadin Push 的 Spring-Boot，Vaadin 8 应用程序

@Push(transport = Transport.WEBSOCKET_XHR)

如果应用程序在没有任何暂停的情况下接收到用户操作，那就没问题。但是，如果几秒钟没有用户请求/操作，就会在控制台上出现以下错误。这使我们的错误日志文件变得混乱。

谢谢

nginx配置:

location / {
        proxy_pass https://ip:port;
        proxy_set_header Host             $host;
        proxy_set_header X-Real-IP        $remote_addr;
        proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-Accel-Internal /internal-nginx-static-location;
        access_log off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
}

Spring Boot 应用程序属性文件

server.tomcat.remote_ip_header = x-forwarded-for
server.tomcat.protocol_header = x-forwarded-proto
server.tomcat.port-header = X-Forwarded-Port    
server.use-forward-headers = true

你在Spring Boot跟踪器上提出的重复问题中提到，同一应用程序可以在Spring Boot 1.5.6上运行。你能否尝试缩减一个示例并在此处分享？你的堆栈中没有任何与Spring相关的内容，因此很难找到问题所在。 - Stephane Nicoll

我在我们的日志中发现了以下HTTP状态101警告，与错误同时出现： GET /vaadinServlet/PUSH?v-uiId=1&v-pushId=***************&X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=2.3.2.vaadin1-javascript&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&Content-Type=application/json;%20charset=UTF-8&X-atmo-protocol=true HTTP/1.1 - tsogtgerel.ts
