Websocket Sink

A simple Websocket Sink implementation.

Options

The following options are supported:

Examples

To verify that the websocket-sink receives messages from other spring-cloud-stream apps, you can use the following simple end-to-end setup.

Step 1: Start Rabbitmq

Step 2: Deploy a time-source

Step 3: Deploy the websocket-sink

Finally start a websocket-sink in trace mode so that you see the messages produced by the time-source in the log:

java -jar <spring boot application for websocket-sink> --spring.cloud.stream.bindings.input=ticktock --server.port=9393 \
	--logging.level.org.springframework.cloud.fn.consumer.websocket=TRACE

You should start seeing log messages in the console where you started the WebsocketSink like this:

Handling message: GenericMessage [payload=2015-10-21 12:52:53, headers={id=09ae31e0-a04e-b811-d211-b4d4e75b6f29, timestamp=1445424778065}]
Handling message: GenericMessage [payload=2015-10-21 12:52:54, headers={id=75eaaf30-e5c6-494f-b007-9d5b5b920001, timestamp=1445424778065}]
Handling message: GenericMessage [payload=2015-10-21 12:52:55, headers={id=18b887db-81fc-c634-7a9a-16b1c72de291, timestamp=1445424778066}]

Actuators

There is an Endpoint that you can use to access the last n messages sent and received. You have to enable it by providing --endpoints.websocketconsumertrace.enabled=true. By default it shows the last 100 messages via the https://host:port/websocketconsumertrace. Here is a sample output:

 [
   {
    "timestamp": 1445453703508,
    "info": {
      "type": "text",
      "direction": "out",
      "id": "2ff9be50-c9b2-724b-5404-1a6305c033e4",
      "payload": "2015-10-21 20:54:33"
    }
  },
  ...
  {
    "timestamp": 1445453703506,
    "info": {
      "type": "text",
      "direction": "out",
      "id": "2b9dbcaf-c808-084d-a51b-50f617ae6a75",
      "payload": "2015-10-21 20:54:32"
    }
  }
]

There is also a simple HTML page where you see forwarded messages in a text area. You can access it directly via https://host:port in your browser.
