= Websocket Supplier

A basic websocket supplier that produced messages through web socket.
The `Supplier` uses the `WebsocketInboundChannelAdapter` from Spring Integration.
This supplier gives you a reactive stream of messages and the supplier has a signature of `Supplier<Flux<Message<?>>>`.
Users have to subscribe to this `Flux` and receive the data.

== Beans for injection

The `WebsocketSupplierConfiguration` auto-configuration provides the following bean:

`websocketSupplier`

You need to inject this as `Supplier<Flux<Message<?>>>`.

You can use `websocketSupplier` as a qualifier when injecting.

Once injected, you can use the `get` method of the `Supplier` to invoke it and then subscribe to the returned `Flux`.

== Configuration Options

All configuration properties are prefixed with `websocket.supplier`.
