maven部署方案之分离业务包

一、思想：

通过将业务包和公共包分离，集中管理所有包，打包时只构建业务包减少项目包的大小和传输时间。

为了观测稳定性，暂通过环境区分，较为频繁的联调环境采用该方式，测试、预发、正式暂保持一体化打包方式不变。

二、方法论：

注意：如果是第一次引入依赖(有依赖变动)，则需要采用默认方式，先在本地构建打包再解压，将其中lib中的所有jar放于服务器上的lib目录中。(可通过步骤二增加一个默认环境的打包方式代替)

步骤一：配置项目启动类所在的pom如下：

<build>
    <plugins>
        
        <plugin> 
        plugin>
    plugins>
build>
 
<profiles>
    <profile>
        
        
        <id>defaultid>
        <properties>
            <project.env>defaultproject.env>
        properties>
        <activation>
            <activeByDefault>trueactiveByDefault>
        activation>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.bootgroupId>
                    <artifactId>spring-boot-maven-pluginartifactId>
                plugin>
            plugins>
        build>
    profile>
 
    <profile>
        
        <id>devid>
        <properties>
            <project.env>devproject.env>
        properties>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.bootgroupId>
                    <artifactId>spring-boot-maven-pluginartifactId>
                    <configuration>
                        <mainClass>启动类路径mainClass>
                        <layout>ZIPlayout>
                        <includes>
                            <include>
                              直接隶属于项目的子包
                            include>
                        includes>
                    configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackagegoal>
                            goals>
                        execution>
                    executions>
                plugin>
            plugins>
        build>
    profile>
profiles>

步骤二：jekins部署命令增加环境

联调环境相比于默认环境需指定dev方式：clean install package -Pdev -Dmaven.test.skip=true

步骤三：修改启动shell脚本指定lib目录

-Dloader.path=$BASE_PATH/lib

三、实践：

因是第一次构建需将项目依赖包都上传至公共管理路径lib，通过maven默认构建解压后上传

步骤一：插件配置

<build>

步骤三：修改启动shell脚本指定lib目录-Dloader.path=$BASE_PATH/lib

#!/usr/bin/env bash
source /etc/profile

then
   echo "kill -9 pid:" $PID
   kill -9 $PID

echo "拷贝新jar到running目录"
cp $BASE_PATH/artifacts/$JENKINS_JOB_NAME/hb-erp-web-0.0.1-SNAPSHOT.jar $BASE_PATH/running/$JAR_NAME

unzip -d $TEMP_PATH  $BASE_PATH/artifacts/$JENKINS_JOB_NAME/hb-erp-web-0.0.1-SNAPSHOT.jar
mv $TEMP_PATH/BOOT-INF/lib/*   $BASE_PATH/lib/
rm -rf  $TEMP_PATH

nohup java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=$DEBUG_PORT,suspend=n -Xms768m -Xmx768m   -jar -Dloader.path=$BASE_PATH/lib $JAR_NAME   --spring.profiles.active=$PROFILE >> $BASE_PATH/logs/$PROJECT_NAME-running.log 2>&1 &
