1. 共同依赖的接口服务搭建 1.1 pom 1.2 公共接口 1.3 maven install 将可依赖jar包安装到本地仓库  2. 生产者服务搭建 2.1 生产者服务pom
2. 配置文件及注册服务
3. 消费者服务搭建 3.1 消费者服务pom 3.2 nacos及dubbo配置 3.3 调用dubbo服务
4. 测试 4.1 生产者服务注册成功 4.2 消费者服务注册成功 4.3 测试controller消费者调用生成者服务 1. 共同依赖的接口服务搭建 1.1 pom 注意 其中build plugins spring-boot-maven-plugin插件classifier为exec表示构建可依赖的jar包及可启动的jar包 ?xml version1.0 encodingUTF-8? project xmlnshttp://maven.apache.org/POM/4.0.0 xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexsi:schemaLocationhttp://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsdmodelVersion4.0.0/modelVersionparentgroupIdhj.example/groupIdartifactIdspringboot-provider/artifactIdversion0.0.1-SNAPSHOT/versionrelativePath/ !– lookup parent from repository –/parentartifactIdsample-api/artifactIdversion0.0.1-SNAPSHOT/versionnamesample-api/namedescriptionsample-api/descriptionpropertiesjava.version1.8/java.version/propertiesdependenciesdependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependency/dependenciesbuildpluginsplugingroupIdorg.springframework.boot/groupIdartifactIdspring-boot-maven-plugin/artifactIdconfigurationclassifierexec/classifier/configuration/plugin/plugins/build/project1.2 公共接口 package hj.example.sample;public interface IHelloService {String sayHello(String name); }1.3 maven install 将可依赖jar包安装到本地仓库  2. 生产者服务搭建 2.1 生产者服务pom 包括4个依赖接口依赖sample-api、nacos配置中心依赖spring-cloud-starter-alibaba-nacos-config、nacos注册中心依赖spring-cloud-starter-alibaba-nacos-discoveryspring-cloud dubbo依赖spring-cloud-starter-dubbo ?xml version1.0 encodingUTF-8?
