 # xfg-frame-archetype - DDD 脚手架
 
+## 重要信息
+
+- 2核4G 可部署整套环境开发学习 [京东云服务器 2核4G 132元/1年或者3年的](https://3.cn/1K-cfT7D)
+- 工程中没有提供 application/case 层，如果你的工程较大，可以使用脚手架构建完工程后，自己新增加此模块
+- 框架使用文档：[https://bugstack.cn/md/road-map/ddd-archetype.html](https://bugstack.cn/md/road-map/ddd-archetype.html) - 此文章下还有系列的 DDD 知识
+
+## Maven - 阿里云镜像
+
+```java
+  <!-- mirrors
+   | This is a list of mirrors to be used in downloading artifacts from remote repositories.
+   |
+   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
+   | However, this repository may have problems with heavy traffic at times, so people have mirrored
+   | it to several places.
+   |
+   | That repository definition will have a unique id, so we can create a mirror reference for that
+   | repository, to be used as an alternate download site. The mirror site will be the preferred
+   | server for that repository.
+   |-->
+  <mirrors>
+    <!-- mirror
+     | Specifies a repository mirror site to use instead of a given repository. The repository that
+     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
+     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
+     | 
+    <mirror>
+        <id>alimaven</id>
+        <mirrorOf>central</mirrorOf>
+        <name>aliyun maven</name>
+        <url>https://maven.aliyun.com/nexus/content/repositories/central/</url>
+    </mirror>
+
+  </mirrors>

+- 没有镜像你可能会出现拉取很慢的问题，以及错误。
