篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了搭建Apache Dubbo工程相关的知识，希望对你有一定的参考价值。

此项目是Spring Cloud Alibaba 和 Dubbo 整合 Demo

版本

Apache Dubbo Demo

JDK 1.8

Dubbo 2.7.2

Nacos Client 1.0.0

Spring Boot 2.1.6.RELEASE

Dubbo Registry Nacos 2.6.6

Dubbo Spring Boot Starter 2.7.1

Spring Cloud Greenwich.SR2

Spring Cloud Alibaba 2.1.0.RELEASE

Alibaba Spring Context Support 1.0.2

Spring Cloud Alibaba Nacos Config 2.1.0.RELEASE

创建父工程 apache-dubbo-demo

此工程只负责管理模块

一、项目结构
