Maven多环境搭建

一般情况下我们的项目需要配置多个环境，可以使用Git的分支管理，也可以使用Maven来管理。

POM文件

Pom文件在</project>前加入以下配置，开发环境，测试环境，生产环境。

<!--分别设置开发，测试，生产环境-->
    <!--打包命令  mvn clean package -Dprofiles.active=pro -->    <profiles>
        <profile>
            <id>dev</id>
            <activation>
                <!--默认激活配置-->
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <environment>dev</environment>
            </properties>
        </profile>
        <!-- 测试 -->
        <profile>
            <id>test</id>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
            <properties>
                <environment>test</environment>
            </properties>
        </profile>
        <!-- 生产 -->
        <profile>
            <id>prod</id>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
            <properties>
                <environment>prod</environment>
            </properties>
        </profile>
    </profiles>

yaml文件

配置application.yml，application-dev.yml，application-test.yml，application-prod.yml，分别配置对应的内容。

application.yml

配置激活环境的变量，注意里面的内容environment和pom是需要对的上的。

spring:
  profiles:
    active: @environment@

各环境配置文件

application-dev.yml，application-test.yml，application-prod.yml 对title的内容配置不同的内容，便于后面验证

server:
  port: 8080

demo:
  title: 我是开发环境 

启动程序验证

注意日志的第三行，展示了启动的环境是开发环境The following 1 profile is active: "dev"

展示内容：我是开发环境

注意：这部分内容写了controller获取了配置文件的title
