Maven对Springboot项目配置文件、依赖分离打包

Springboot项目配置文件、依赖分离打包(一)

使用maven-assembly-plugin进行配置分离

assembly.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<assembly>
    <!-- 可自定义，这里指定的是项目环境 -->
    <!-- xxx.tar.gz  -->
    <id>${name}</id>

    <!-- 打包的类型，如果有N个，将会打N个类型的包 -->
    <formats>
        <format>tar.gz</format>
        <format>zip</format>
    </formats>

    <includeBaseDirectory>true</includeBaseDirectory>

    <fileSets>
        <!-- 配置文件打包-打包至config目录下 -->
        <fileSet>
            <directory>src/main/resources/</directory>
            <outputDirectory>config</outputDirectory>
            <fileMode>0644</fileMode>
            <includes>
                <include>application.yml</include>
                <include>*.xml</include>
                <include>*.properties</include>
            </includes>
        </fileSet>
        <!-- 启动文件目录 -->
        <fileSet>
            <directory>${basedir}/src/bin</directory>
            <outputDirectory>bin</outputDirectory>
            <fileMode>0755</fileMode>
            <includes>
                <include>**.sh</include>
                <include>**.bat</include>
            </includes>
        </fileSet>
    </fileSets>

    <dependencySets>
        <dependencySet>
            <!-- 依赖库 -->
            <outputDirectory>lib</outputDirectory>
            <scope>runtime</scope>
            <fileMode>0755</fileMode>
            <excludes>
                <exclude>${project.groupId}:${project.artifactId}</exclude>
            </excludes>
        </dependencySet>
        <dependencySet>
            <outputDirectory>boot</outputDirectory>
            <fileMode>0755</fileMode>
            <includes>
                <include>${project.groupId}:${project.artifactId}</include>
            </includes>
        </dependencySet>
    </dependencySets>
</assembly>

Pom.xml文件配置

pom文件中build属性的配置

运行

1.直接运行 java -jar xxxx.jar即可

2.编写shell/bash脚本

在bin目录下编写脚本文件如下：

shell

#! /bin/sh

HOME = '/opt/xxx/boot'
JAR_HOME = 'xxx.jar'

cd $HOME
nohup java -jar $JAR_HOME

bash

@echo off
rem ======================================================================
rem windows startup script
rem
rem ======================================================================
rem startup jar

java -jar ../boot/xxx.jar

pause

项目目录如下
