1.创建dubboApi

package com.imooc.ecommerce.service;/*** @author lan* @date 2024/3/6*/
public interface DubboApiService {public String dubboTest(String arg);}

2.创建provider

package com.imooc.ecommerce;import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;/*** @author lan* @date 2023/12/30*/
@EnableDiscoveryClient
@SpringBootApplication
@EnableDubbo
public class DubboProviderApplication {public static void main(String[] args) {SpringApplication.run(DubboProviderApplication.class, args);}}

创建Dubboapi实现类 这里要引入api模块

package com.imooc.ecommerce.service;import org.apache.dubbo.config.annotation.DubboService;/*** @author lan* @date 2024/3/6*/
@DubboService
public class DubboServiceImpl implements DubboApiService {@Overridepublic String dubboTest(String arg) {System.out.println("test success");return "test success";}
}

<dependency><groupId>com.imooc.ecommerce</groupId><artifactId>e-commerce-dubbo3-api</artifactId><version>1.0-SNAPSHOT</version><scope>compile</scope>
</dependency>

3.创建consumer

package com.imooc.ecommerce;import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;/*** @author lan* @date 2023/12/30*/
@EnableDiscoveryClient
@SpringBootApplication
@EnableDubbo
public class DubboConsumerApplication {public static void main(String[] args) {SpringApplication.run(DubboConsumerApplication.class, args);}}

4 consumer调用

package com.imooc.ecommerce;import com.imooc.ecommerce.service.DubboApiService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;/*** @author lan* @date 2023/12/30*/@SpringBootTest
public class DubboConsumerApplicationTest {@DubboReference(url = "dubbo://192.168.31.24:20880/com.imooc.ecommerce.service.DubboApiService")private DubboApiService dubboApiService;@Testpublic void test() {String sss = dubboApiService.dubboTest("sss");System.out.println(sss);}
}

在provider控制台找
