A Demo gateway written in Java using Netty

To run this app, you need to install Java 8, Maven. Run these apps below as: Simpler server -> gateway -> client

Simple server

Using Spring boot, accept http request and just return the response with error rate is 10%. Run on default port 8080.

Gateway

Using Netty Gateway address config variable live in com.demo.gateway.NettyServer

    private static final int GATEWAY_PORT=6969;
private static final String GATEWAY_HORT="localhost";

We need to point gateway to server, change the variable in com.demo.gateway.service.GetPriceService if needed

    public static final String PRICE_URL="http://localhost:8080/price";

Gateway have a http client to connect to simple server

We can choose which kind of client to use in config file.
Change config in gateway/src/main/resources/config.yaml
The clientType in config file can be reference from com.demo.gateway.GatewayConfiguration.ClientType

Client

Using Netty. Config variable to point to gateway and number of client live in ClientMain.java

    private static final String GATEWAY_SERVER_HOST="localhost";
private static final int GATEWAY_SERVER_PORT=6969;
private static final int NUM_OF_CLIENT=200;

Each client will send a message to gateway and print response when receiving.
