Maven Profile精讲

一个项目通常都会有多个不同的运行环境，例如开发环境，测试环境、生产环境等。而不同环境的构建过程很可能是不同的，例如数据源配置、插件、以及依赖的版本等。每次将项目部署到不同的环境时，都需要修改相应的配置，这样重复的工作，不仅浪费劳动力，还容易出错。为了解决这一问题，Maven 引入了 Profile 的概念，通过它可以为不同的环境定制不同的构建过程。

Profile 的类型

Profile 可以分为 3  个类型，它们的作用范围也各不相同。

类型位置有效范围
Per ProjectMaven 项目的 pom.xml 中只对当前项目有效
Per User用户主目录（％USER_HOME％）/.m2/settings.xml 中对本机上该用户所有 Maven 项目有效
GlobalMaven 安装目录（%MAVEN_HOME%）/conf/settings.xml 中对本机上所有 Maven 项目有效

声明 Profile 

Maven 通过 profiles 元素来声明一组 Profile 配置，该元素下可以包含多个 profile 子元素，每个 profile 元素表示一个 Profile 配置。每个 profile 元素中通常都要包含一个 id 子元素，该元素是调用当前 Profile 的标识。

定义 Profile 的一般形式如下：

  1. <profiles>
  2.     <profile>
  3.         <id>profile id</id>
  4.         ....
  5.     </profile>
  6.     <profile>
  7.         <id>profile id</id>
  8.         ....
  9.     </profile>
  10. </profiles>

除此之外，Profile 中还可以声明一些其他的 POM 元素，但不同位置的 Profile 所能声明的 POM 元素也是不同的。


1. 在 pom.xml 中声明的 Profile，由于其能够随着 pom.xml 一起存在，它被提交到代码仓库中，被 Maven 安装到本地仓库或远程仓库中，所以它能够修改或增加很多 POM 元素，其中常用的元素如下表。

dependencies 
plugins 
dependencyManagement 
distributionManagement 
modules 
properties 
reporting 
buildplugins

resources
testResources
directory
filters

2. 在 setting.xml 中声明的 Profile 是无法保证能够随着 pom.xml 一起被分发的，因此 Maven 不允许用户在该类型的 Profile 修改或增加依赖或插件等配置信息，它只能声明以下范围较为宽泛的元素。

  • repositories：仓库配置。
  • pluginRepositories：插件仓库配置。
  • properties：键值对，该键值对可以在 pom.xml 中使用。

激活 Profile

Profile 能够在项目构建时，修改 POM 中配置或者添加一些额外的配置元素。用户可以通过多种方式激活 Profile，以实现不同环境使用不同的配置，执行不同的构建过程。

Profile 可以通过以下 6 种方式激活：

  • 命令行激活
  • settings.xml 文件显示激活
  • 系统属性激活
  • 操作系统环境激活
  • 文件存在与否激活
  • 默认激活


下面我们以一个 Maven 项目为例，分别对以上 6 种激活方式进行介绍。

准备 Maven 项目

1. 创建一个名为 maven 的项目，并在其 src/main/resources 目录下有 3 个环境 properties 配置文件。

  • env.properties：默认配置文件
  • env.test.properties：测试环境配置文件
  • env.prod.properties：生产环境配置文件

2. 该项目目录结构如图 1 所示。

3. 在 pom.xml 中定义三个不同的 Profile，将 maven-antrun-plugin:run 目标绑定到 default 生命周期的 test 阶段上，以实现在不同的 Profile 中进行不同的操作。

命令行激活

我们可以在命令行中使用 mvn 命令行参数 -P 加上 Profile 的 id 来激活 Profile，多个 id 之间使用逗号隔开。例如，激活 test1 和 test2 两个 Profile, 命令如下：

  • mvn clean install -Ptest1,test2

打开命令行窗口，跳转到 pom.xml 所在的目录，执行以下 mvn 命令，激活 id 为 test 的 Profile。

  • mvn clean test -Ptest

执行结果如下。

settings.xml 文件显示激活

在本地仓库的 settings.xml 文件中添加如下配置，激活指定的 Profile。

  1. <activeProfiles>
  2.     <activeProfile>test</activeProfile>
  3. </activeProfiles>

Maven 本地仓库的 settings.xml 文件，默认位于 %USER_HOME%/.m2 目录下。

打开命令行窗口，跳转到 pom.xml 所在的目录下，执行以下 mvn 命令。

  • mvn clean test

系统属性激活

用户可以配置当某个系统属性存在时，激活指定的 Profile。例如，我们在 id 为 prod 的 profile 元素中添加以下配置，表示当系统属性 user 存在，且值等于 prod 时，自动激活该 Profile。

  1. <activation>
  2.       <property>
  3.         <name>user</name>
  4.         <value>prod</value>
  5.     </property>
  6. </activation>

打开命令行窗口，跳转到 pom.xml 所在的目录。执行命令，其中参数 -D 选项用来指定系统临时属性。

  • mvn clean test -Duser=prod

执行结果如下。

操作系统环境激活

Maven 还可以根据操作系统环境自动激活指定的 Profile。例如，将以下配置（本地计算机操作系统环境信息）添加到 pom.xml 文件中的 id 为 normal 的 Profile 中。

  1. <activation>
  2.     <os>
  3.         <name>Windows 10</name>
  4.         <family>Windows</family>
  5.         <arch>amd64</arch>
  6.         <version>10.0</version>
  7.     </os>
  8. </activation>

打开命令行窗口，跳转到 pom.xml 所在的目录下，执行以下 mvn 命令。

  • mvn clean test

执行结果如下。

文件存在与否激活

Maven 可以根据某些文件存在与否，来决定是否激活 Profile。例如，在 id 为 prod 的 Profile 中添加以下配置，该配置表示当 env.prod.properties 文件存在，且 env.test.properties 文件不存在时，激活该 Profile。

  1. <activation>
  2.         <file>
  3.             <exists>./src/main/resources/env.prod.properties</exists>
  4.             <missing>./src/main/resources/env.test.properties</missing>
  5.         </file>
  6. </activation>

将 env.test.properties 从项目中删除，打开命令行窗口，跳转到 pom.xml 所在目录，执行以下命令。

  1. mvn clean test

执行结果如下。

默认激活

我们可以在声明 Profile 时，指定其默认激活。例如，在 id 为 normal 的 Profile 中添加以下配置，指定该 Profile 默认激活。

  1. <activation>
  2.     <activeByDefault>true</activeByDefault>
  3. </activation>

打开命令行窗口，跳转到 pom.xml 所在目录，执行以下命令。

  1. mvn clean test
