+采用按功能拆分模块的开发方式，项目结构如下：
+
+> 项目结构按模块的层次顺序介绍，实际 IDE 中 `continew-admin-common` 模块会因为字母排序原因排在上方
+>
+
+```
+continew-admin  全局通用项目配置及依赖版本管理
+  ├─continew-admin-webapi  API 模块（存放 Controller 层代码，打包部署的模块）
+  ├─continew-admin-system  系统管理模块（存放系统管理模块相关功能，例如：部门管理、角色管理、用户管理等）
+  ├─continew-admin-common  公共模块（存放公共工具类，公共配置等）
