Detailed explanation of profiles in idea

profile is mainly to solve the problems of different variables and configurations required by different environments.

profile generally appears in two places: settings.xml, pom.xml

In settings.xml, it is generally used for warehouse selection (only aliyun warehouses can configure settings.xml in this way)

In pom.xml, it is generally used to activate the environment configuration

<profiles>
        <profile>
            <id>local</id>
            <properties>
                <profiles.active>local</profiles.active>
            </properties>
        </profile>
        <profile>
            <id>elk</id>
            <properties>
                <profiles.active>elk</profiles.active>
            </properties>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
    </profiles>

The build code used in conjunction with profile packaging is configured as follows (combined with the application-${env}.properties file)

Part of application-${env}.properties

application-prepub.properties 中 spring.profiles.active=prepub-qa
application-daily.properties 中 spring.profiles.active=daily
