Maven根据不同个环境打包, 获取不同的配置文件_package.environment

作者：盐析白兔 | 2024-03-22 07:38:18

踩

package.environment

本地的测试配置文件与内测的配置，甚至线上的配置不一样, 以前比较土的做法就是每次复制粘贴。然后不停的来回改文件。

现在是将本地的开发环境，内测的，生产环境的，各个不同的配置文件放在配置文件夹里。例如：

在项目的资源文件夹 resources下面再新建四个文件夹：

local: 表示本地开发环境的配置文件

internal : 表示内测环境配置文件

product : 表示生产环境配置环境

除了三这不同的配置文件之外，还有一些是共同的，与环境无关的，就可以放在同一个文件夹里，统一管理，这个文件夹就是：

public : 表示共同的配置文件

结果如一下：

相应在的pom里进行设置：


		<resources>
			<resource>
				<directory>src/main/resources</directory>
				<filtering>true</filtering>
				<excludes>
					<exclude>local/*</exclude>
					<exclude>internal/*</exclude>
					<exclude>product/*</exclude>
					<exclude>public/*</exclude>
				</excludes>
			</resource>
		</resources>

完整理的 pom.xml 内容如下，整个贴上，仅供参考：

对这个pom 再多作一些说明：


	<profiles>
		<profile>
			<id>local</id><!-- 本地开发环境 -->
			<properties>
				<package.environment>local</package.environment>
			</properties>
			<activation>
				<activeByDefault>true</activeByDefault>
			</activation>
		</profile>
		<profile>
			<id>internal</id><!-- 内测环境 -->
			<properties>
				<package.environment>internal</package.environment>
			</properties>
		</profile>
		<profile>
			<id>product</id><!-- 生产环境 -->
			<properties>
				<package.environment>product</package.environment>
			</properties>
		</profile>
	</profiles>

这里就是不同的resources文件夹, 在这里可以区分本地、内测、生产;

<activeByDefault>true</activeByDefault>

设置为true的就是默认被激活的. 所以后面打包默认就是本地;


<!-- 不同的环境，使用不同的配置文件 -->
						<resource>
							<directory>src/main/resources/${package.environment}</directory>
							<targetPath>WEB-INF/classes</targetPath>
							<filtering>true</filtering>
						</resource>

<directory>src/main/resources/${package.environment}</directory>

这边指的是动态文件夹

最后别忘了

<filtering>true</filtering>

这个一定要设置成true

最后，打包，使用Maven的生命周期，比如，打包生产环境的配置文件，package 打包生成 war 文件。

mvn -Pproduct package;
