SpringBoot的啓動類

import com.alibaba.dubbo.config.annotation.Service;
import com.smart.springboot.api.HelloServiceFacade;

/**

@Service(version = "1.0.0",timeout = 20000)

定義服務消費者

服務的引用（便於服務的管理）

import com.alibaba.dubbo.config.annotation.Reference;
import com.smart.springboot.api.HelloServiceFacade;
import org.springframework.stereotype.Component;

/**
 * @author : cuantianhou 2020/1/14
 */
@Component
public class ConsumerManager {

    @Reference(version="1.0.0")
    private HelloServiceFacade helloServiceFacade;


    public HelloServiceFacade getHelloServiceFacade(){
        return helloServiceFacade;
    }
}

消費者的定義

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

/**
 * @author : cuantianhou 2020/1/14
 */
@Component
public class HelloServiceConsumer extends ConsumerManager{

 @Autowired
 private  ConsumerManager consumerManager;


    public void sayHello(){
        consumerManager.getHelloServiceFacade().sayHello();
    }

}

SpringBoot啓動類

import com.smart.springboot.consumer.HelloServiceConsumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

/**
 * @author : cuantianhou 2020/1/14
 */

@SpringBootApplication
public class SpringBootDubboConsumer {

    public static void main(String[] args) {

        ConfigurableApplicationContext configurableApplicationContext =   SpringApplication.run(SpringBootDubboConsumer.class,args);
        HelloServiceConsumer helloSereviceConsumer = configurableApplicationContext.getBean(HelloServiceConsumer.class);
        helloSereviceConsumer.sayHello();
    }
}

配置

dubbo.scan.basePackages=包路徑

dubbo.application.id=springboot-dubbo-consumer
dubbo.application.name=springboot-dubbo-consumer

dubbo.protocol.id=dubbo
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880


dubbo.registry.id=zookeeper-registry
dubbo.registry.address=zk地址
dubbo.registry.protocol=zookeeper

dubbo.monitor.protocol=registry
dubbo.consumer.check=false
