• 定义接口（用户服务注册使用）

public interface HelloService {    String sayHello(String name);}

Provider

首先需要依赖Common

• yml

dubbo:   application:     name: my-application  registry:     address: zookeeper://localhost:2181

• 实现定义的接口（Service是apache.dubbo）

@Servicepublic class HelloServiceImpl implements HelloService {    @Override    public String sayHello(String name) {        return "Hello, " + name + "!";    }}

• 启动类（@EnableDubbo）

@EnableDubbo@SpringBootApplicationpublic class Application {    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }}

Consumer

首先需要依赖Common

• Controller（@Reference注解）

@RestControllerpublic class HelloController {    @Reference    private HelloService helloService;    @GetMapping("/hello/{name}")    public String sayHello(@PathVariable String name) {        return helloService.sayHello(name);    }}

Zookeeper
