纯干货|微服务架构 CI/CD 实战
概述
现有 Demo,一项目某块业务拆分为如下几个模块
book-web 前端,采用 Vue MVVM,服务端 Thymeleaf SSR 渲染,友好 SEO MPA。服务端 路由,Spring MVC
book-gateway 微服务网关,Spring Cloud Gateway
book-service 接口提供方,Spring Cloud Alibaba Dubbo 服务消费方
book-server 数据承载方,Spring Cloud Alibaba Dubbo 服务提供方
book-common 实体,Dubbo 接口 jar
cloud-common 微服务公共 jar
common pom
school-parent 最上级 父工程 pom
本篇内容使用Jenkis实现自动构建。
common 继承关系
在项目根路径下执行,Maven 命令 mvn clean install -pl com.lab:book-common -am -Ptest
,截取输出如下

Maven 环境
root@jazz-pc:/opt# mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /usr/local/apache-maven-3.6.3
Java version: 11.0.7, vendor: Oracle Corporation, runtime: /usr/local/java/jdk-11.0.7
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "5.3.0-51-generic", arch: "amd64", family: "unix"
在settings.xml 文件中,添加国内镜像
<mirror>
<id>aliyunmaven</id>
<mirrorOf>*</mirrorOf>
<name>阿里云公共仓库</name>
<url>https://maven.aliyun.com/repository/public</url>
</mirror>
顶级父工程 pom.xml 添加,跳过Maven单元测试 编译和执行
<maven.test.skip>true</maven.test.skip>
<skipTests>true</skipTests>
如果有 Maven Nexus,则另外添加设置,install 替换为 deploy
Jenkins相关配置
启动Jenkis
nohup java -jar /usr/local/jenkins/jenkins.war --ajp13Port=-1 --httpPort=8086 >/usr/local/jenkins/jenkins.out 2>&1 &
Jenkins JDK 环境 >=1.8 and <=11 目前最新版本不支持 Java 14
cd /root/.jenkins/updates
sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json
Git or SVN

Jenkins CI/CD
Global Tool Configuration 设置好,JDK,Maven,Git
新建 Item,Freestyle project,如下
