Microservice with a Websocket transport

In this post, we will look at a simple component to publish market data and accept orders. How can this be accessed using websockets as a transport?

Interface for messages from the client to the server

public interface GUIGateway {
    void enableMarketData(boolean enabled);
    void newOrder(Order order);
}

Interface for messages from the server to the client

public interface GUIGatewayListener {
    void market(MarketData marketData);
    void order(OrderStatus orderStatus);
}
