快速上手（三）服务提供者 - 项目搭建

项目结构

项目是以Maven构建的多模块项目，1个父项目，3个子项目；

实现用于和数据库交互的 dao 层

Sub Model - server

• 作为服务提供者的主体，是个 Springboot 项目，统筹其他子模块；
• 实现 api 子模块中向注册中心暴露的接口；
• 整合 Dubbo & Zookeeper & MySQL & Log；

pom.xml

• 有自己的 <artifactId>server</artifactId>；
• 依赖于 model 子模块；
• 注意 spring-boot-starter-web 中要 exclusion 两个 log 实现；
