My error shows up in the console of my browser:
"WebSocket connection to 'ws://localhost:32768/DspClusterWebServices/myHandler' failed: Unexpected response code: 200"
I am using Spring Websockets 4.1.5 and Tomcat 8.0.18. My WebSocketConfigurer implementation class looks like:
@Configuration
@Controller
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer
{
class MyHandler implements WebSocketHandler
{
@Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception
{
System.out.println("afterConntectionEstablished called");
}
...implements rest of functions with a System.out.println and false for supportsPartialMessages()
}
}
@Override registerWebSocketHandlers(WebSocketHandlerRegistry registry)
{
registry.addHandler(myHandler(), "myHandler").withSockJS();
}
@Bean
public WebSocketHandler myHandler()
{
return new MyHandler();
}
}
My testWebsocketClient.js tries to connect with this code, but has a error code of 200:
websocket = new WebSocket("ws://localhost:8080/myApp/myHandler");
I cannot figure out what to try next. I thought that this would cause the afterConnectionEstablished(WebSocketSession session) method to fire? Isn't code 200 good?

After you append /websocket (to your URL), it will give you the error
Failed to parse Origin header value [null]
;) , which then will in turn lead you to that link.
You'll have to add .setAllowedOrigins("*") to your addHandler() method, and then it could finally work!
