    @Override
    public void start() {
        final var server = GrpcServer.server(vertx);
        final var greeter = new GreeterGrpc.GreeterImplBase() {
            @Override
            public void sayHello(final HelloRequest request, final StreamObserver<HelloReply> responseObserver) {
                System.out.println("Hello " + request.getName());
                final var reply = HelloReply.newBuilder().setMessage(request.getName()).build();

                responseObserver.onCompleted();
            }

                .bridge(greeter)
                .bind(server);
        vertx.createHttpServer().requestHandler(server).listen(4240);

    public static void main(String[] args) {
     
        new GreeterClient().start();
    }

   
    public void start() {
        final var channel = NettyChannelBuilder.forAddress("127.0.0.1", 4240).usePlaintext()
                .build();
        final var sub = GreeterGrpc.newBlockingStub(channel);
        for (int i = 0; i < 10; i++) {
            System.out.println("开始idx\t" + i);
            final var data = HelloRequest.newBuilder().setName("qwx" + i).build();
            final var resp = sub.sayHello(data);
            System.out.println("resp\t" + resp.getMessage());
            System.out.println("结束idx\t" + i);
        }
        channel.shutdown() ;
    }
}
