文件结构 

代码部分

1、新建provider-server导入pom依赖

<dependency><groupId>org.apache.dubbo</groupId><artifactId>dubbo-spring-boot-starter</artifactId><version>2.7.3</version></dependency><dependency><groupId>com.github.sgroschupf</groupId><artifactId>zkclient</artifactId><version>0.1</version></dependency><dependency><groupId>org.apache.curator</groupId><artifactId>curator-framework</artifactId><version>2.12.0</version></dependency><dependency><groupId>org.apache.curator</groupId><artifactId>curator-recipes</artifactId><version>2.12.0</version></dependency><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.4.14</version><!--            排除slf4j--><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency>

2、TicketService

package com.guo.service;public interface TicketService {public  String getTicket();
}

3、TicketServiceImpl

package com.guo.service;import org.apache.dubbo.config.annotation.Service;
import org.springframework.stereotype.Component;//服务注册与发现@Service  //可以被扫描，启动后自动注册到注册中心
@Component
public class TicketServiceImpl implements TicketService{@Overridepublic String getTicket() {return "郭俊";}
}

4、application.properties

server.port=8001dubbo.application.name=provider-serverdubbo.registry.address=zookeeper://127.0.0.1:2181dubbo.scan.base-packages=com.guo.service

 5、新建consumer-server导入pom依赖

<dependency><groupId>org.apache.dubbo</groupId><artifactId>dubbo-spring-boot-starter</artifactId><version>2.7.3</version></dependency><dependency><groupId>com.github.sgroschupf</groupId><artifactId>zkclient</artifactId><version>0.1</version></dependency><dependency><groupId>org.apache.curator</groupId><artifactId>curator-framework</artifactId><version>2.12.0</version></dependency><dependency><groupId>org.apache.curator</groupId><artifactId>curator-recipes</artifactId><version>2.12.0</version></dependency><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.4.14</version><!--            排除slf4j--><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency>

6、TicketService

package com.guo.service;public interface TicketService {public  String getTicket();
}

7、UserService

 8、application.properties

server.port=8002dubbo.application.name=consumer-serverdubbo.registry.address=zookeeper://127.0.0.1:2181

 测试部分

1、启动zookeeper服务

 2、启动provider，连接成功

 3、编写测试类

@SpringBootTest
class ConsumerServerApplicationTests {@AutowiredUserService userService;@Testvoid contextLoads() {userService.buyTicket();}}

测试结果 

 成功在注册中心拿到，测试成功
