springboot zookeeper dubbo demo

学习目标：

提示：这里可以添加学习目标

例如：

• springboot 以zookeeper为注册中心，集成dubbo

学习内容：

提示：这里可以添加要学的内容

例如：

1. zookeeper环境搭建
2. dubbo admin 部署
3. 注册服务到zookeeper，再dubbo admin上能看到
4. 问题总结

学习产出：

提示：这里统计学习计划的总量

例如：

• 直接上代码

1.生产者（服务提供者）

1.1 pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.4.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<dubbo.version>2.7.3</dubbo.version>
<zkclient.version>0.10</zkclient.version>
<curator.version>2.13.0</curator.version>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>${zookeeper.version}</version>
        <exclusions>

            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo-spring-boot-starter</artifactId>
        <version>${dubbo.version}</version>
    </dependency>
    <dependency>
        <groupId>com.101tec</groupId>

        </exclusions>
    </dependency>
</dependencies>

1.2 application.yml

server:
  port: 10202
dubbo:
  application:
    name: provier-server
  registry:
    address: zookeeper://注册中心地址:端口
  protocol:
    name: dubbo
    port: 28081

1.3 启动类

@EnableDubbo
@SpringBootApplication
public class DubboProvider {
    public static void main(String[] args) {
        SpringApplication.run(DubboProvider.class);
    }
}

1.4 需要暴露的接口

public interface TickApi {
    String getTick();
}

1.5 接口实现

@Component
@Service(version="1.0.0")//dubbo中的注解
public class TickApiService implements TickApi {
    @Autowired
    private TickService tickService;

    @Override
    public String getTick() {
        return tickService.getTick();
    }
}

@Service//spring注解
public class TickService {
    public String getTick() {
        return "tick" UUID.randomUUID().toString().replace("-","");
    }

}

启动工程，再dubbo中可以看到

 2.消费者

2.1 pom.xml 文件同上

2.2 application.yml

server:
  port: 10203
dubbo:
  application:
    name: consumer-server
  registry:
    address: zookeeper://101.43.49.178:21810
  protocol:
    name: dubbo
    port: 28080

2.3 启动了同上

2.4 消费服务

@RestController
@RequestMapping
public class UserController {
   //注解为dubbo提供
   @Reference(version = "1.0.0")
    private TickApi tickApi;
    @GetMapping("tick")
    public String getTick(){
        return tickApi.getTick();
    }
}

2.5 启动服务，能再dubbo admin中查看
