Springboot瘦身打包

准备

• springboot 版本 2.3.9.RELEASE
• maven

assembly.xml 配置

我这边放在resources下面

<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">
    <!--
        必须写，否则打包时会有 assembly ID must be present and non-empty 错误
        这个名字最终会追加到打包的名字的末尾，如项目的名字为 speed-api-0.0.1-SNAPSHOT,
        则最终生成的包名为 speed-api-0.0.1-SNAPSHOT-bin.zip
     -->
    <id>bin</id>
    <!-- 打包后的文件格式,可以是zip,tar,tar.gz,tar.bz2,jar,war,dir -->
    <formats>
        <format>dir</format>
    </formats>

    <includeBaseDirectory>false</includeBaseDirectory>
    <dependencySets>
        <dependencySet>
            <!-- 不使用项目的artifact，第三方jar不要解压，打包进zip文件的lib目录 -->
            <useProjectArtifact>false</useProjectArtifact>
            <outputDirectory>lib</outputDirectory>
            <unpack>false</unpack>

        <!-- 把项目自己编译出来的jar文件，打包进zip文件的根目录 -->
