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

docker 和 docker-compose 适合 测试环境使用，生产环境用 Kubernetes，相关内容本公众号都有，可以自行查阅。

Maven 环境
root@jazz-pc:/opt# mvn -vApache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)Maven home: /usr/local/apache-maven-3.6.3Java version: 11.0.7, vendor: Oracle Corporation, runtime: /usr/local/java/jdk-11.0.7Default locale: zh_CN, platform encoding: UTF-8OS 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 -
Jenkins 安装一般会卡住 2 次，则是去国外下载插件数据缓慢的原因，kill -9 进程 ID，ps -ef | grep jenkins 找到进程 ID。
第一次卡住修改 ：/root/.jenkins/hudson.model.UpdateCenter.xml文件里面链接内容为国内镜像地址 https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
第二次卡住执行替换命令：
cd /root/.jenkins/updatessed -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
Item book-common
-
源码管理，选择 Git，填写 Repository URL 和 Credentials 设置 Jenkins 凭据 -
构建 Execute shell
#!/bin/bashcd ./schoolmvn clean install -pl com.lab:book-common -am -Ptestecho 'install ok!'
Item book-web
-
源码管理 略 -
Execute shell

Dockerfile
-
位置和 pom.xml 路径平级，book-server 内容如下，其他略
FROM adoptopenjdk/openjdk11:jdk-11.0.7_10-alpineVOLUME ["/tmp","/data/logs"]COPY ./target/book-server-0.0.1-SNAPSHOT.jar book-server.jarENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/book-server.jar","&"]
book-web 执行构建 Build Now
book-web 前端 浏览器访问
login.html 登录模板示例页面，调用 /api/login 接口，内容如下
<!DOCTYPE html><html xmlns:th="http://www.thymeleaf.org"><head><meta charset="UTF-8"/><title>理想生活上天猫，登录页面</title><r th:insert="common/header::#headerApp"/></head><body><div id="app"><el-row :gutter="20"><el-col :span="24"> </el-col></el-row><el-row :gutter="20"><el-col :span="1"> </el-col><el-col :span="4"><img alt="我是一只天猫" src="//img.alicdn.com/tfs/TB11ojWRXXXXXafaFXXXXXXXXXX-190-27.png"></el-col><el-col :span="19"> </el-col></el-row><el-row :gutter="20"><el-col :span="15"><img alt="九寨沟" src="/images/JiuZhaiGou.jpg" width="800" height="490"></el-col><el-col :span="7"><template><el-tabs v-model="activeName" @tab-click="handleClick"><el-tab-pane label="密码登录" name="first"><el-form ref="form" :model="userForm" label-width="80px"><el-row><el-input placeholder="会员名/邮箱/手机号" prefix-icon="el-icon-user" v-model="userForm.name"></el-input></el-row><el-row><el-input placeholder="请输入密码" prefix-icon="el-icon-lock" v-model="userForm.password" show-password></el-input></el-row><el-row><el-button @click="login" type="danger">登录</el-button></el-row></el-form></el-tab-pane><el-tab-pane label="短信登录" name="second">短信登录</el-tab-pane></el-tabs></template></el-col><el-col :span="2"> </el-col></el-row></div><r th:replace="common/footer::.footerApp"/><script src="/js/request.js"></script><script>new Vue({el: '#app',data: {userForm:{}, activeName: 'first'},methods: {login() {request({url: '/api/login',method: 'post',data: this.userForm,headers: {'content-type': 'application/json;charset=UTF-8',"token": ''}}).then(response=>{var res = response.data;this.$message(res.message);})},handleClick(tab, event) {//console.log(tab, event);}}});</script></body></html>
