首先,我们先了解一下maven-assembly-plugin。它是一个用于maven的插件,可以将多个模块打包成一个分发包,方便分发和部署。其支持多种方式的打包,包括单一的jar包、zip、tar.gz等。
接下来,我们介绍如何使用该插件实现SpringCloud的多级目录打包。具体实现步骤如下:
1.在pom.xml文件中,添加maven-assembly-plugin插件的相关配置:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.1.1</version>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<mainClass>com.example.Application</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<finalName>my-project-1.0.0</finalName>
<appendAssemblyId>false</appendAssemblyId>
<outputDirectory>${project.basedir}/target</outputDirectory>
<assembly>
<id>package</id>
<formats>
<format>tar.gz</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<fileSets>
<fileSet>
<directory>${project.basedir}/src/main/resources</directory>
<outputDirectory>conf</outputDirectory>
</fileSet>
<fileSet>
<directory>${project.build.directory}</directory>
<outputDirectory>lib</outputDirectory>
<includes>
<include>**/*.jar</include>
</includes>
</fileSet>
</fileSets>
</assembly>
</configuration>
</execution>
</executions>
</plugin>
2.配置文件的打包方式:在上述配置中,相关配置项如下:
package :assembly插件的id,可以自定义命名:打包的格式,此处为tar.gz格式 :是否包含根目录
3.指定各个文件和目录的打包路径:在上述配置中,filesSet元素对应的是一个文件或目录的打包路径和输出路径,例如:
${project.basedir}/src/main/resources :需要打包的文件或目录路径conf :打包后的文件或目录输出路径
4.编译打包:在项目的根目录下执行以下命令:
mvn clean package
上述命令可以编译你的SpringCloud项目,并使用maven-assembly-plugin插件进行打包。
示例1:将SpringCloud项目打包成tar.gz格式,包含conf和lib目录,conf目录包含application.yml文件,命令如下:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
<id>package</id>
<formats>
<format>tar.gz</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<fileSets>
<fileSet>
<directory>${project.basedir}/src/main/resources</directory>
<outputDirectory>conf</outputDirectory>
</fileSet>
<fileSet>
<directory>${project.build.directory}</directory>
<outputDirectory>lib</outputDirectory>
<includes>
<include>**/*.jar</include>
</includes>
</fileSet>
</fileSets>
</assembly>
示例2:将SpringCloud项目打包成zip格式,包含config目录和lib目录,config目录包含application.yml文件,命令如下:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
<id>package</id>
<formats>
<format>zip</format>
</formats>
<includeBaseDirectory>true</includeBaseDirectory>
<fileSets>
<fileSet>
<directory>${project.basedir}/src/main/resources</directory>
<outputDirectory>config</outputDirectory>
<includes>
<include>application.yml</include>
</includes>
</fileSet>
<fileSet>
<directory>${project.build.directory}</directory>
<outputDirectory>lib</outputDirectory>
<includes>
<include>**/*.jar</include>
</includes>
</fileSet>
</fileSets>
</assembly>
通过上述两个示例,你可以更好地了解SpringCloud Maven-assembly-plugin的多级目录打包方案。
