如何从Android连接到Spring Websocket

Question

i am using grails 3.1.1

i already try to find some documentation and question like this .

this is my code in ChatController

class ChatController {

    SimpMessagingTemplate brokerMessagingTemplate
    def corporateUserService
    def index={

    }

    @MessageMapping("/chat")
    @SendTo("/queue/chat")
    protected String hello(DestinationUser map) {
        brokerMessagingTemplate.convertAndSend "/queue/chat", map
    }
}

and i already deploy this application, for example :

https://somedomain.com

how can i connect from android to my webapplication's websocket?

i tried

wss://somedomain.com/chat
wss://somedomain.com/queue/chat

but it still cannot connect.

i am trying follow this tutorial github

like this..

AsyncHttpClient.getDefaultInstance().websocket("ws://satubangau.com/app/hello", null, new AsyncHttpClient.WebSocketConnectCallback() {
        @Override
        public void onCompleted(Exception ex, WebSocket webSocket) {
            Log.d(TAG, "onCompleted: ");
            if (ex != null) {
                ex.printStackTrace();
                return;
            }
            webSocket.send("a string");
            webSocket.send(new byte[10]);
            webSocket.setStringCallback(new WebSocket.StringCallback() {
                public void onStringAvailable(String s) {
                    Log.d(TAG, "onStringAvailable: I got a string: " + s);
                }
            });
            webSocket.setDataCallback(new DataCallback() {
                public void onDataAvailable(DataEmitter emitter, ByteBufferList byteBufferList) {
                    Log.d(TAG, "onDataAvailable: I got some bytes!");
                    // note that this data has been read
                    byteBufferList.recycle();
                }
            });
        }
    });

您是否尝试过在Android上使用WebSocket客户端库，例如https://github.com/koush/AndroidAsync ？
