springboot中profiles.active的配置

1.application.yml改动

设置profiles.active 变量，添加不同环境的配置信息

2.pom文件修改

添加<profiles>节点内容

<profiles>
    <profile>
        <id>dev</id>
        <properties>
            <profiles.active>dev</profiles.active>
            <modifier>-dev</modifier>
        </properties>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
    </profile>
    <!-- 测试环境 -->
    <profile>
        <id>test</id>
        <properties>
            <profiles.active>test</profiles.active>
            <modifier>-test</modifier>
        </properties>
    </profile>
    <!-- STAGE环境 -->
    <profile>
        <id>stage</id>
        <properties>
            <profiles.active>stage</profiles.active>
            <modifier>-stage</modifier>
        </properties>
    </profile>
    <!-- 生成环境 -->
    <profile>
        <id>prod</id>
        <properties>
            <profiles.active>prod</profiles.active>
            <modifier>-prod</modifier>
        </properties>
    </profile>
</profiles>

3.build节点修改

build节点下添加

<resources>
    <resource>
        <!--打包该目录下的 application.yml -->
        <directory>src/main/resources</directory>
        <!-- 启用过滤 即该资源中的变量将会被过滤器中的值替换 -->
        <filtering>true</filtering>
    </resource>
</resources>

PS:步骤三不做修改，可能造成启动失败。
