springboot

一、一个配置文件：不推荐

# 默认激活dev配置
spring:
  profiles:
    active: "dev"

---

spring:
  config:
    activate:
      on-profile: "dev"

desc: this is dev environment

---

spring:
  config:
    activate:
      on-profile: "test"

desc: this is test environment

---

spring:
  config:
    activate:
      on-profile: "prod"

desc: this is prod environment

二、不同环境，不同文件

在Spring Boot中多环境配置文件名需要满足application-{profile}.properties的格式

其中{profile}对应你的环境标识，比如：

    application-dev.properties：开发环境
    application-test.properties：测试环境
    application-prod.properties：生产环境
至于哪个具体的配置文件会被加载，需要在application.properties文件中通过spring.profiles.active属性来设置，其值对应{profile}值。
如：spring.profiles.active=test就会加载application-test.properties配置文件内容

三、profiles目录

创建src/main/resources/profiles目录

profiles目录下创建dev、prod、test等文件夹，每个文件夹下创建application.yml

<profiles>
        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <profileActive>dev</profileActive>
            </properties>
            <build>
                <resources>
                    <resource>
                        <directory>src/main/profiles/dev</directory>
                    </resource>
                    <resource>
                        <directory>src/main/resources</directory>
                    </resource>
                </resources>
            </build>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <profileActive>prod</profileActive>
            </properties>
            <build>
                <resources>
                    <resource>
                        <directory>src/main/profiles/prod</directory>
                    </resource>
                    <resource>
                        <directory>src/main/resources</directory>
                    </resource>
                </resources>
            </build>
        </profile>
    </profiles>

mvn clean package -Pprod -U  
# 或者
mvn clean package -DprofileActive=prod -U
