Maven 中的 profile
2021-06-29 16:43:28 更新
- Maven 中有一个概念叫做:
profile
,它的诞生主要是为了解决不同环境所需的不同变量、配置等问题。 - 有了
profile
,可以根据激活的条件,启动不同条件下的配置信息。 -
profile
是可以有多个的,也可以同时激活多个 profile
,方便自由组合。 -
profile
一般可以在三个地方:settings.xml
,pom.xml
,profiles.xml
(这个不常用) - 在
settings.xml
上,一般大家用来做仓库的选择,比如以下settings.xml
代码:
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository>D:\maven\my_local_repository</localRepository>
<pluginGroups> </pluginGroups>
<proxies> </proxies>
<profiles> <profile> <id>nexus</id> <repositories> <repository> <id>nexus</id> <url>http://192.168.1.73:8081/repository/maven-public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>nexus</id> <url>http://192.168.1.73:8081/repository/maven-public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile> <profile> <id>aliyun</id> <repositories> <repository> <id>aliyun</id> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>aliyun</id> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile> </profiles>
<activeProfiles> <activeProfile>nexus</activeProfile> </activeProfiles>
</settings>
- 以上代码中
profile
就做一件事:设置全局的 profile
,一个是 nexus
仓库,一个是 aliyun
仓库,默认激活的是 nexus 仓库。(activeProfiles
) - 在
pom.xml
中,一般用来激活环境配置,比如以下代码:
<profiles> <profile> <id>dev</id> <properties> <package.environment>dev</package.environment> </properties> <activation> <activeByDefault>true</activeByDefault> </activation> <build> <resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*</include> </includes> <filtering>true</filtering> </resource> <resource> <directory>src/main/env/${package.environment}</directory> <includes> <include>**/*</include> </includes> <filtering>true</filtering> </resource> </resources> <finalName>${project.artifactId}</finalName> </build> </profile> <profile> <id>product</id> <properties> <package.environment>product</package.environment> </properties> <activation> <activeByDefault>false</activeByDefault> </activation> <build> <resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*</include> </includes> <filtering>true</filtering> </resource> <resource> <directory>src/main/env/${package.environment}</directory> <includes> <include>**/*</include> </includes> <filtering>true</filtering> </resource> </resources> <finalName>${project.artifactId}</finalName> </build> </profile></profiles>
- 以上代码中
profile
就做一件事:打包的时候,默认是 dev
模式,打包 src/main/env/dev
下的配置文件,如果选择 product
则打包 src/main/env/product
下的配置文件。
