不考虑配置中心时，将多环境的配置就放在项目的resource目录下

配置

<profiles>
        <profile>
            <id>local</id>
            <properties>
                <!-- 环境标识，需要与配置文件的名称相对应 -->
                <profiles.active>local</profiles.active>
                <logging.level>info</logging.level>
                <monitor.username>ruoyi</monitor.username>
                <monitor.password>123456</monitor.password>
            </properties>
        </profile>
        <profile>
            <id>dev</id>
            <properties>
                <!-- 环境标识，需要与配置文件的名称相对应 -->
                <profiles.active>dev</profiles.active>
                <logging.level>info</logging.level>
                <monitor.username>ruoyi</monitor.username>
                <monitor.password>123456</monitor.password>
            </properties>
            <activation>
                <!-- 默认环境 -->
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <profiles.active>prod</profiles.active>
                <logging.level>warn</logging.level>
                <monitor.username>ruoyi</monitor.username>
                <monitor.password>123456</monitor.password>
            </properties>
        </profile>
    </profiles>

===============================================================

spring:
  profiles:
    active: @profiles.active@

完成配置或可以直接通过maven选择环境

打包

mvn clean package -DskipTests=true -P dev

关键就是上面的 -P 来指定具体的环境
