<!-- Spring Boot Starter --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId><version>2.3.0.RELEASE</version></dependency><!-- Dubbo Starter --><dependency><groupId>org.apache.dubbo</groupId><artifactId>dubbo-spring-boot-starter</artifactId><version>2.7.8</version></dependency><!-- ZooKeeper 注册中心 --><dependency><groupId>org.apache.dubbo</groupId><artifactId>dubbo-registry-zookeeper</artifactId><version>2.7.8</version></dependency>

• 定义接口（用户服务注册使用）

publicinterfaceHelloService{StringsayHello(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）

@ServicepublicclassHelloServiceImplimplementsHelloService{@OverridepublicStringsayHello(String name){return"Hello, "+ name +"!";}}

• 启动类（@EnableDubbo）

@EnableDubbo@SpringBootApplicationpublicclassApplication{publicstaticvoidmain(String[] args){SpringApplication.run(Application.class, args);}}

Consumer

**

首先需要依赖Common

**

• Controller（@Reference注解）

@RestControllerpublicclassHelloController{@ReferenceprivateHelloService helloService;@GetMapping("/hello/{name}")publicStringsayHello(@PathVariableString name){return helloService.sayHello(name);}}

Zookeeper

• 安装脚本
