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
