A thin, synchronous wrapper on vertx’ Zookeeper Backend service discovery. Can be plug into any JVM based project.

Example usage:

public class App {
    public static void main(String[] args) throws Exception {
        ServiceDiscovery discovery = new ZookeeperServiceDiscovery(Vertx.vertx(), createConfig());
        // Service was create with at service type.
        /**
        * @see {@link com.liemlhd.starter.service_discovery.ServiceType}
        * */
        ServiceInfo serviceInfo = new ServiceInfo(() -> "test");
        ServiceInfo.Address address = new ServiceInfo.Address();
        address.setHost("localhost");
        address.setPort(12345);
        serviceInfo.setName("test");
        serviceInfo.setAddress(address);
        // Register it
        Future<ServiceInfo> promise = discovery.register(serviceInfo);
        ServiceInfo s = promise.get();
        System.out.println("registered service info: " + s);
        // Do something with your service.
        // Search for it
        SearchCriteria searchCriteria = SearchCriteria.name("test");
        Future<List<ServiceInfo>> services = discovery.find( searchCriteria );
        System.out.println("services = " + services);
        // ...
        // Do something with your services.
        // Clean up
        // Your service will be clean after it shutdown anyway
        // but there a may be some delay, so for god's sake, DIY!
        discovery.deregister(serviceInfo.getId()); // We do use serviceInfo.getId, so dont forget to saved your registered service info.

        ZkConfig config = new ZkConfig();
