代码在dubbo-demo 模块 的子模块 dubbo-demo-api

provider 提供端

public class Application {

    private static final String REGISTRY_URL = "zookeeper://127.0.0.1:2181";

    public static void main(String[] args) {
        startWithBootstrap();
    }

    private static void startWithBootstrap() {
        ServiceConfig<DemoServiceImpl> service = new ServiceConfig<>();
        service.setInterface(DemoService.class);
        service.setRef(new DemoServiceImpl());

        DubboBootstrap bootstrap = DubboBootstrap.getInstance();
        bootstrap
                .application(new ApplicationConfig("dubbo-demo-api-provider"))
                .registry(new RegistryConfig(REGISTRY_URL))
                .protocol(new ProtocolConfig(CommonConstants.DUBBO, -1))
                .service(service)
                .start()
                .await();
    }
}

consumer 消费端

public class Application {

    private static final String REGISTRY_URL = "zookeeper://127.0.0.1:2181";

    public static void main(String[] args) {
        runWithBootstrap();
    }

    private static void runWithBootstrap() {
        ReferenceConfig<DemoService> reference = new ReferenceConfig<>();
        reference.setInterface(DemoService.class);
        reference.setGeneric("true");

        DubboBootstrap bootstrap = DubboBootstrap.getInstance();
        bootstrap
                .application(new ApplicationConfig("dubbo-demo-api-consumer"))
                .registry(new RegistryConfig(REGISTRY_URL))
                .protocol(new ProtocolConfig(CommonConstants.DUBBO, -1))
                .reference(reference)
                .start();

        DemoService demoService = bootstrap.getCache().get(reference);
        String message = demoService.sayHello("dubbo");
        System.out.println(message);

        // generic invoke
        GenericService genericService = (GenericService) demoService;
        Object genericInvokeResult = genericService.$invoke(
                "sayHello", new String[] {String.class.getName()}, new Object[] {"dubbo generic invoke"});
        System.out.println(genericInvokeResult.toString());
    }
}
