spring boot 多环境配置

首先在pom.xml中配置profile

      <profile>
            <id>dev</id>
            <properties>
                <profileActive>dev</profileActive>
            </properties>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
        <profile>
            <id>test</id>
            <properties>
                <profileActive>test</profileActive>
            </properties>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
        </profile>

然后根据不同的环境编写不同的配置文件（说明一下：application-dev.yml是本地开发配置文件，application为springboot的主配置文件application.yml的名字，dev为开发环境，在pom.xml的profile里进行配置）

在pom.xml中根据环境获取不同的配置文件（注意：${profileActive}要和<profileActive>一样）

           <resource>
                <directory>src/main/resources/environment/${profileActive}</directory>
                <excludes>
                    <exclude>environment/${profileActive}/${profileActive}.properties</exclude>
                </excludes>
            </resource>

在读取配置文件的时候要先排除环境下的文件

<!--指定资源的位置 -->
	    <resource>
		<directory>src/main/resources</directory>
                    <filtering>true</filtering>
                    <excludes>
                        <exclude>environment/**</exclude>
                    </excludes>
            </resource>

dev.properties的内容是

profile.active=dev

在application.yml里需要这样配置

spring:
    profiles:
        active: '@[email protected]'
        include: email,xmyb
mybatis:
    mapperLocations: classpath:cn/linkengine/pre/service/aiom/mapper/*.xml
    configLocation: classpath:mybatis.xml

注意：1.'@[email protected]'必须加单引号或双引号，高版本springboot是用@[email protected]的，低版本是${}，且必须和properties文件里的key一样。

2.mybatis.xml只要classpath:mybatis.xml即可引入，因为或根据不同的环境把mybatis.xml引入到配置文件的根目录下

最后要在pom.xml里把properties文件给filter（注意：必须在读取配置文件的时候<filtering>true</filtering>）

       <filters>
            <filter>src/main/resources/environment/${profileActive}/${profileActive}.properties</filter>
        </filters>

整个pom.xml内容为

        <build>
                <filters>
                    <filter>src/main/resources/environment/${profileActive}/${profileActive}.properties</filter>
                </filters>
		<resources>
			<!--指定资源的位置 -->
			<resource>
				<directory>src/main/resources</directory>
                                <filtering>true</filtering>
                                <excludes>
                                    <exclude>environment/**</exclude>
                                </excludes>
                        </resource>
                        <resource>
                            <directory>src/main/resources/environment/${profileActive}</directory>
                            <excludes>
                                <exclude>environment/${profileActive}/${profileActive}.properties</exclude>
                            </excludes>
                        </resource>
		</resources>
        </build>

<profiles>
        <profile>
            <id>dev</id>
            <properties>
                <profileActive>dev</profileActive>
            </properties>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
        <profile>
            <id>test</id>
            <properties>
                <profileActive>test</profileActive>
            </properties>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
        </profile>
</profiles>
