二、配置好skywalking agent
三、服务提供者端的依赖

            </dependency>

        </dependencies>
    </dependencyManagement>

</project>

四、增加skywalking的配置bean

package cn.edu.tju.config;

import io.micrometer.observation.ObservationHandler;
import io.micrometer.observation.ObservationRegistry;
import org.apache.dubbo.rpc.model.ApplicationModel;
import org.apache.skywalking.apm.toolkit.micrometer.observation.SkywalkingDefaultTracingHandler;
import org.apache.skywalking.apm.toolkit.micrometer.observation.SkywalkingReceiverTracingHandler;
import org.apache.skywalking.apm.toolkit.micrometer.observation.SkywalkingSenderTracingHandler;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ObservationConfiguration {

    @Bean
    ObservationRegistry getIt(){
        return ObservationRegistry.create();
    }
    @Bean
    ApplicationModel applicationModel(ObservationRegistry observationRegistry) {
        ApplicationModel applicationModel = ApplicationModel.defaultModel();
        observationRegistry.observationConfig()
                .observationHandler(new ObservationHandler.FirstMatchingCompositeObservationHandler(
                        new SkywalkingSenderTracingHandler(), new SkywalkingReceiverTracingHandler(),
                        new SkywalkingDefaultTracingHandler()
                ));
        applicationModel.getBeanFactory().registerBean(observationRegistry);
        return applicationModel;
    }
}

五、定义服务接口和服务实现：

package cn.edu.tju.service;

public interface DemoService {

    String sayHello(String name);
}

package cn.edu.tju.service;


import org.apache.dubbo.config.annotation.DubboService;

@DubboService
public class DemoServiceImpl implements DemoService {


    public String sayHello(String name) {

        return "Hay " + name;
    }




}

六、服务提供者的配置文件和启动类：

server:
  port: 9953
spring:
  application:
    name: dubbosky
dubbo:
  application:
    name: dubbosky
  protocol:
    name: dubbo
    port: 28030
  registry:
    address: nacos://xx.xx.xx.xx:8848

package cn.edu.tju;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

七、服务消费者添加依赖，类似服务提供者
八、服务消费者添加接口定义，同服务提供者

package cn.edu.tju.service;

public interface DemoService {

    String sayHello(String name);
}

九、服务消费者自己的业务逻辑，其中通过@DubboReference来调用dubbo服务

package cn.edu.tju.service;

import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.stereotype.Service;

@Service
public class RemoteService {
    @DubboReference
    private DemoService demoService;

    public String getInfo(){
        return demoService.sayHello("amadeus");
    }
}

十、服务消费者端的controller

package cn.edu.tju.controller;

import cn.edu.tju.service.RemoteService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class DemoController {
    @Autowired
    private RemoteService remoteService;
    @RequestMapping("/hi")
    public String hi(){
        return remoteService.getInfo();
    }
}

十一、服务消费者端的启动类和配置文件类似于服务提供者。
十二、访问接口

十二、在skywalking中查看服务调用的指标
