基于SpringBoot开源项目JeeSite的持续交互介绍

2021-06-10 14:54:03 作者：互联网

一、实战项目介绍- JeeSite

基于Spring Boot 2.0
数据存储MySQL
语言：Java
规模大小：适中，适合初学者

源码地址：https://gitee.com/thinkgem/jeesite4
本次项目演练地址：https://gitee.com/sfboy/iJeeSite4 ，在原作者的项目上，增加了Pipline持续集成的脚本，便于实战使用

二、环境准备

Spring Boot项目运行配置：MySQL+Java+Maven
MySQL安装参考：https://www.cnblogs.com/feng0815/p/14041558.html
Maven安装参考: https://www.cnblogs.com/feng0815/p/14354226.html
Java安装参考：自行百度。。

三、项目配置、调试、运行 3.1 初始化

打开 JeeSite4/web/src/main/resources/config/application.yml，填写数据库配置（地址、IP端口、用户名、密码）
进入项目路径 JeeSite4/web/bin，运行初始化脚本程序init-data.sh（Windows下运行init-data.bat）

初始化脚本用来创建初始数据，初始化前要保证数据库中有jeesite数据库，否则会造成无法连接jeesite数据库，初始化失败

开始执行

执行结束

3.2 配置项目 3.2.1 使用IDE编译

添加JeeSite4/root/pom.xml Maven根节点到IDE的maven view中，其余依赖module会根据配置一起导入
Maven编译、打包
在Maven view 中选中JeeSite Root下Lifecycle中的clean + install，然后单击运行按钮

3.2.2 在命令行编译

进入到JeeSite4/root目录下，运行mvn clean install

3.3 运行项目demo 3.3.1 在IDE运行

展开JeeSite Web → Plugins → spring-boot → spring-boot:run ，单击运行

运行成功

访问项目：http://localhost:8980/a/login

输入用户名system，密码admin，点击登录

3.3.2 在命令行运行

进入到JeeSite4/web目录下，运行：mvn clean spring-boot:run -Dmaven.test.skip=true(Dmaven.test.skip=true，不运行单元测试)

运行成功

四、Tomcat部署持续交互实战 4.1 Tomcat运行和配置入门

下载，官网：https://tomcat.apache.org/

直接解压到安装目录即可

Tomcat基本配置

启动：bin/startup.sh
停止：bin/shutdown.sh
配置文件：conf/server.xml（配置端口号）
日志：logs/catalina.out

4.2 使用Jenkins Pipline任务部署Spring应用到Tomcat 4.2.1 Jenkins参数配置，设置Pipline脚本中所需的参数

创建Jenkins Pipline任务

设置代码分支，默认分支为master

4.2.2 配置Pipline脚本

运行，构建任务

构建成功，打开项目页面：http://localhost:8080/a/login

Pipline代码如下(Scripted Pipeline)：

node('master') {
    stage('同步源码') {
            git([url: 'https://gitee.com/sfboy/iJeeSite4.git', branch: '${branch}'])
    }

    stage('maven编译打包') {
        sh '''
            . ~/.bash_profile
            
            export pwd=`pwd`
            export os_type=`uname`
            cd web/src/main/resources/config
            if [[ "${os_type}" == "Darwin" ]]; then
                sed -i "" "s/mysql_ip/${mysql_ip}/g" application.yml
                sed -i "" "s/mysql_port/${mysql_port}/g" application.yml
                sed -i "" "s/mysql_user/${mysql_user}/g" application.yml
                sed -i "" "s/mysql_pwd/${mysql_pwd}/g" application.yml
            else
                sed -i "s/mysql_ip/${mysql_ip}/g" application.yml
                sed -i "s/mysql_port/${mysql_port}/g" application.yml
                sed -i "s/mysql_user/${mysql_user}/g" application.yml
                sed -i "s/mysql_pwd/${mysql_pwd}/g" application.yml
            fi
            
            cd $pwd/root
            mvn clean install -Dmaven.test.skip=true
            
            cd $pwd/web
            mvn clean package spring-boot:repackage -Dmaven.test.skip=true -U
        '''
    }

    stage('停止 tomcat') {
        sh '''
            ## 停止tomcat的函数, 参数$1带入tomcat的路径$TOMCAT_PATH
            killTomcat()
            {
                pid=`ps -ef|grep $1|grep java|awk '{print $2}'`
                echo "tomcat Id list :$pid"
                if [ "$pid" = "" ]
                then
                  echo "no tomcat pid alive"
                else
                  kill -9 $pid
                fi
            }
            ## 停止Tomcat
            killTomcat $tomcat_home
        '''
    }

    stage('清理环境') {
        sh '''
            ## 删除原有war包
            rm -f $tomcat_home/webapps/ROOT.war
            rm -rf $tomcat_home/webapps/ROOT
        '''
    }

    stage('部署新的war包') {
        sh '''
            cp web/target/web.war $tomcat_home/webapps/
            cd $tomcat_home/webapps
            mv web.war ROOT.war
        '''
    }

    stage('启动tomcat') {
        sh '''
            JENKINS_NODE_COOKIE=dontkillme
            cd $tomcat_home/bin
            sh startup.sh
        '''
    }
}

五、docker部署持续交互实战

Pipline脚本(Declarative Pipeline)

pipeline {
    agent {
        label 'master'
    }

    environment {
        docker_image_name = 'jeesite4'
        docker_container_name = 'iJeesite4'
        PATH = "/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin"
    }

    parameters {
        string(name: 'branch', defaultValue: 'master', description: 'Git branch')
    }

    stages{
        stage('同步源码') {
            steps {
                git url:'https://gitee.com/sfboy/iJeeSite4.git', branch:'$branch'
            }
        }

        stage('设定配置文件'){
            steps{
                sh '''
                    . ~/.bash_profile
            
                    export os_type=`uname`
                    cd ${WORKSPACE}/web/bin/docker
                    if [[ "${os_type}" == "Darwin" ]]; then
                        sed -i "" "s/mysql_ip/${mysql_docker_ip}/g" application-prod.yml
                        sed -i "" "s/mysql_port/${mysql_port}/g" application-prod.yml
                        sed -i "" "s/mysql_user/${mysql_user}/g" application-prod.yml
                        sed -i "" "s/mysql_pwd/${mysql_pwd}/g" application-prod.yml
                    else
                        sed -i "s/mysql_ip/${mysql_docker_ip}/g" application-prod.yml
                        sed -i "s/mysql_port/${mysql_port}/g" application-prod.yml
                        sed -i "s/mysql_user/${mysql_user}/g" application-prod.yml
                        sed -i "s/mysql_pwd/${mysql_pwd}/g" application-prod.yml
                    fi
                '''
            }
        }

        stage('Maven 编译'){
            steps {
                sh '''
                    . ~/.bash_profile 
                                      
                    cd ${WORKSPACE}/root
                    mvn clean install -Dmaven.test.skip=true
                    
                    cd ${WORKSPACE}/web
                    mvn clean package spring-boot:repackage -Dmaven.test.skip=true -U
                '''
            }
        }

        stage('停止 / 删除 现有Docker Container/Image '){
            steps {
                script{
        
                    try{
                        sh 'docker stop $docker_container_name'
                    }catch(exc){
                        echo "The container $docker_container_name does not exist"
                    }

                    try{
                        sh 'docker rm $docker_container_name'
                    }catch(exc){
                        echo "The container $docker_container_name does not exist"
                    }

                    try{
                        sh 'docker rmi $docker_image_name'
                    }catch(exc){
                        echo "The docker image $docker_image_name does not exist"
                    }
                }
            }
        }

        stage('生成新的Docker Image'){
            steps {
                sh '''
                    . ~/.bash_profile
                    cd ${WORKSPACE}/web/bin/docker
                    rm -f web.war
                    cp ${WORKSPACE}/web/target/web.war .
                    docker build -t $docker_image_name .
                '''
            }
        }

        stage('启动新Docker实例'){
            steps {
                sh '''
                    docker run -d --name $docker_container_name -p 8981:8980 $docker_image_name
                '''
            }
        }
    }
}

六、生产与测试环境分离持续交互实战

需要在Pipline脚本中区分环境，具体脚本如下

pipeline {
    agent {
        label 'master'
    }

    environment {
        docker_image = 'jeesite4'
        docker_container = 'iJeesite4'
        PATH = "/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin"
    }

    parameters {
        string(name: 'branch', defaultValue: 'master', description: 'Git branch')
        choice(name: 'env', choices: ['prod', 'qa'], description: 'Environment Type')
    }

    stages{
        stage('同步源码') {
            steps {
                git url:'https://gitee.com/sfboy/iJeeSite4.git', branch:'${branch}'
            }
        }

        stage('设定配置文件'){
            steps{
                sh '''
                    . ~/.bash_profile         
                    
                    if [[ "${env}" == "prod" ]]; then
                        export mysql_ip=${mysql_prod_ip}
                        export mysql_port=${mysql_prod_port}
                    else
                        export mysql_ip=${mysql_qa_ip}
                        export mysql_port=${mysql_qa_port}
                    fi
                    
                    export os_type=`uname`
                    cd ${WORKSPACE}/web/bin/docker
                    if [[ "${os_type}" == "Darwin" ]]; then
                        sed -i "" "s/mysql_ip/${mysql_ip}/g" application-${env}.yml
                        sed -i "" "s/mysql_port/${mysql_port}/g" application-${env}.yml
                        sed -i "" "s/mysql_user/${mysql_user}/g" application-${env}.yml
                        sed -i "" "s/mysql_pwd/${mysql_pwd}/g" application-${env}.yml
                        sed -i "" "s/<env>/${env}/g" Dockerfile-param
                    else
                        sed -i "s/mysql_ip/${mysql_ip}/g" application-${env}.yml
                        sed -i "s/mysql_port/${mysql_port}/g" application-${env}.yml
                        sed -i "s/mysql_user/${mysql_user}/g" application-${env}.yml
                        sed -i "s/mysql_pwd/${mysql_pwd}/g" application-${env}.yml
                        sed -i "s/<env>/${env}/g" Dockerfile-param
                    fi
                '''
            }
        }

        stage('Maven 编译'){
            steps {
                sh '''
                    . ~/.bash_profile
