I have a Web Socket with Spring and SockJs, I have to expose the Socket also for a "WebSocket" standard.

I have my handler:

@Override public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) { registry.addHandler(mySocketHandler(), "/mySocket").setAllowedOrigins("*"); }

When I create the websocket via browser, with this:

var ws = new WebSocket('wss://localhost:8443/myApp/mySocket')

I have the following error:

WebSocket connection to 'wss://localhost:8443/myApp/mySocket' failed: Error during WebSocket handshake: Unexpected response code: 405

Any suggestions?

Thanks.

  • So your server supports encrypted connections? How did you configure that? Commented Apr 6, 2016 at 12:55
  • sure it supports them. My app is served in https and uses already sockets with sockjs. Commented Apr 6, 2016 at 13:00
  • "uses already sockets with sockjs" - which can use fallback options. Maybe websockets are not yet configured to be used with SSL/TLS. Commented Apr 6, 2016 at 13:16
  • I don't understand. The application can normally connect to web sockets using sockjs; I'm trying to add a normal WebSocket but I have that error... Commented Apr 6, 2016 at 13:26
  • "The application can normally connect to web sockets using sockjs" That was my point: Maybe it does not(!) connect via websockets but uses a fallback option, because websockets don't work on your server. SockJS can(!) use websockets. Commented Apr 6, 2016 at 13:56

I have found the solution.

This error occoured because in the @Configuration component the annotation @EnableWebSocket was missing.

After adding @EnableWebSocket, the connection was correctly established.
