（一）Alian 的 Spring Cloud Bom（Bom即材料清单）

一、创建bom工程

1.1、第一步

1.2、第二步

1.3、第三步

总体来说它就是一个maven工程。

二、pom文件配置

pom.xml

我这里选择的依赖都是比较新且稳定的版本，你也可以根据自己的需要进行调整，主要有

Spring Boot
Spring Cloud
Eureka
Swagger
Redis分布式锁
分布式定时任务锁
Ebean
DozerMapping
MySQL
mockito单元测试
其他常用工具包

这里对 dependencies 、 dependencyManagement 做一个说明

类型	作用
dependencies	项目具体使用的依赖
dependencyManagement	依赖管理，项目并不会引用依赖到项目，只有在子项目中直接应用 groupId 和 artifactId ，而不用指定版本，才会从父项目中继承该项，如果子项目中指定了版本号，那么会使用子项目中指定的jar版本

这里对 repositories 、 pluginRepositories 、 distributionManagement 做一个说明

类型	作用
repositories	配置依赖的下载地址，可以是私服和其他镜像源结合（比如阿里云）
pluginRepositories	配置插件的下载地址（如很多打包的插件）
distributionManagement	打包成库文件的上传地址，一般是上传到私服

三、maven私服配置

3.1、镜像源配置

在你maven安装路径下面的 conf/setting.xml 中的 mirrors标签 里添加成如下（私服 + 阿里云）：

 <mirrors><mirror><!-- 私服的地址--><id>nexus-repos</id><name>Team Nexus Repository</name><url>http://192.168.0.210:8080/nexus/content/groups/public</url> <mirrorOf>central</mirrorOf>  </mirror><mirror><!-- 阿里云的地址--><id>alimaven</id><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><mirrorOf>central</mirrorOf></mirror></mirrors>

这样的好处是你可以优先从你的私服下载，私服没有了也可以通过阿里云镜像去下载。

3.2、私服账户配置

同时还需要在 conf/setting.xml 中的 servers标签 配置成如下：

  <servers><!--release版本--><server>  <id>releases</id>  <username>私服的账号</username>  <password>私服密码</password>  </server> <!--snapshots版本--><server>  <id>snapshots</id>  <username>私服的账号</username>  <password>私服密码</password>  </server> </servers>

四、脚本

能够使用这些脚本的前提是你的maven环境安装好了。不会的可以，可以问问度娘。（我这里是windows环境开发的，用的是bat，当然如果是linux，你就要编写xx.sh文件了）

4.1、安装脚本

install.bat

cd %~dp0
cd..call mvn clean install -Dmaven.test.skip=truecd bin
pause

4.2、发布脚本

deploy.bat

cd %~dp0
cd..call mvn clean deploy -Dmaven.test.skip=truecd bin
pause

4.3、打包脚本

package.bat

cd %~dp0
cd..call mvn clean package -Ppack -X -Dmaven.test.skip=truecd bin
pause

这三个脚本，后面的项目会经常用到哦！

五、安装到本地或发布到私服

执行我的脚本即可…

结语

BOM全称是Bill Of Materials，译作材料清单，BOM的好处是用来管理一个工程的所有依赖版本信息，这样各个工程的版本比较一致，减少了不同版本中冲突和不兼容的问题，良好的项目都是从一个bom开始，本文介绍了它的创建，以及非常实用的脚本，我们接下里的工程都会用到的哦。
