背景

远程部署时spring boot 包，比较大。可以采用依赖库和业务包分离的方式。提供一个脚本进行自动部署

maven 配置分离jar包

 <build><finalName>${project.artifactId}</finalName><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>${spring-boot.version}</version><configuration><!-- 导入系统路径包 --><includeSystemScope>true</includeSystemScope><includes><include><groupId>nothing</groupId><artifactId>nothing</artifactId></include></includes></configuration></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-jar-plugin</artifactId><configuration><archive><!-- 生成的jar中不要包含pom.xml和pom.properties这两个文件 --><addMavenDescriptor>false</addMavenDescriptor><manifest><addClasspath>true</addClasspath><classpathPrefix>lib/</classpathPrefix><!--这里需要修改为你的项目的主启动类--><mainClass>com.ruoyi.RuoYiApplication</mainClass></manifest></archive></configuration></plugin><!--设置将 lib 拷贝到应用 Jar 外面--><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-dependency-plugin</artifactId><executions><execution><id>copy-lib</id><phase>package</phase><goals><goal>copy-dependencies</goal></goals><configuration><outputDirectory>target/lib</outputDirectory><excludeTransitive>false</excludeTransitive><stripVersion>false</stripVersion><includeScope>runtime</includeScope></configuration></execution></executions></plugin></plugins></build>

部署脚本

}sync
stop
sleep 2
start

• 优点
  • 依赖包不变化不会同步，减少上传的文件
  • 每次都同步业务包，保证准确性
  • 提升发布速度

要求

• windows 的wsl下可用
• 需要和服务器配置ssh互信

进一步封装

#!/bin/bash./mvnw -T 1C clean package -P prod./push_run.sh
