SpringBoot多环境分离resources和lib进行打包

为了更便捷的在本地进行开发，偶尔的又会涉及到测试和生产打包，每个环境下的配置不尽相同，需要配置多环境的配置文件，避免打包时还要自己特意去修改配置文件

SpringBoot项目的默认配置文件在main/resources下的application.properties且通过配置项 spring.profiles.active 来设置多环境属性，所以可以就此文件创建多个环境的application.properties，只是spring.profiles.active区分开特定的环境值，再通过maven进行配置打包

首先创建各环境下的配置文件，目录是这样

dev为开发环境，spring.profiles.active=dev

test为测试环境，spring.profiles.active=test

prod为生产环境，spring.profiles.active=prod

pom.xml文件添加

<profiles>
    <!-- 开发环境 -->
    <profile>
        <id>dev</id>
        <properties>
            <package.environment>dev</package.environment>
        </properties>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
    </profile>
    <!-- 测试环境 -->
    <profile>
        <id>test</id>
        <properties>
            <package.environment>test</package.environment>
        </properties>
    </profile>
    <!-- 生产环境 -->
    <profile>
        <id>prod</id>
        <properties>
            <package.environment>prod</package.environment>
        </properties>
    </profile>
</profiles>

拆分resources、lib打包zip文件

    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <excludes>
                <exclude>dev/*</exclude>
                <exclude>test/*</exclude>
                <exclude>prod/*</exclude>
            </excludes>
        </resource>
        <resource>
            <directory>src/main/resources/${package.environment}</directory>
        </resource>
    </resources>

最后使用命令给开发环境进行打包

mvn clean install -Dmaven.test.skip=true -Pdev

打包的文件结构为

使用 java -jar test-1.0.jar 运行即可
