一、需求概述

普通Java工程 docker-show 实现了定时打印docker应用信息，现在需要将其打包成可执行Jar部署到服务器端运行。

打包方式分为2种：

1. 一体化可执行包
2. 带外部依赖lib的可执行包

二、代码结构

三、运行结果

此项目使用了线程池定时打印docker应用名，端口信息

四、打包设置

1. 一体化可执行包

pom文件中引入 maven-assembly-plugin插件，核心配置

			<!-- 方式一：带dependencies运行包 --><plugin><artifactId>maven-assembly-plugin</artifactId><version>3.5.0</version><configuration><appendAssemblyId>false</appendAssemblyId><archive><manifest><mainClass>com.fly.simple.MainRun</mainClass></manifest></archive><descriptorRefs><!--将所有外部依赖JAR都加入生成的JAR包--><descriptorRef>jar-with-dependencies</descriptorRef></descriptorRefs></configuration><executions><execution><!-- 配置执行器 --><id>make-assembly</id><phase>package</phase><!-- 绑定到package阶段 --><goals><goal>single</goal><!-- 只运行一次 --></goals></execution></executions></plugin>

2. 带外部依赖lib的可执行包

pom文件中引入 maven-dependency-plugin、maven-jar-plugin插件，核心配置

			<!-- 方式二：外部依赖lib目录运行包 --><!-- 将项目依赖包复制到<outputDirectory>指定的目录下 --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-dependency-plugin</artifactId><version>3.1.2</version><executions><execution><id>copy-dependencies</id><phase>package</phase><goals><goal>copy-dependencies</goal></goals><configuration><outputDirectory>${project.build.directory}/lib</outputDirectory><excludeArtifactIds>lombok</excludeArtifactIds><includeScope>runtime</includeScope><!-- 默认为test，包含所有依赖 --></configuration></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-jar-plugin</artifactId><version>3.2.0</version><configuration><archive><manifest><addClasspath>true</addClasspath><classpathPrefix>lib</classpathPrefix><mainClass>com.fly.simple.MainRun</mainClass></manifest><manifestEntries><Class-Path>./</Class-Path></manifestEntries></archive></configuration></plugin>

五、打包运行

1. 源码放送

https://gitcode.com/00fly/demo

git clone https://gitcode.com/00fly/demo.git

或者使用下面的备份文件恢复成原始的项目代码

2. 打包执行

#完整打包
mvn clean package#一体化可执行包
mvn clean package -f pom-deps.xml#带外部依赖lib的可执行包
mvn clean package -f pom-lib.xml

3. 打包结果
