maven 使用profiles

调用：mvn -P bj package

maven的pom.xml中的

<profiles>
        <profile>
            <id>bj</id>    //mvn -P bj package 
            <activation>
                <activeByDefault>false</activeByDefault>  //不是默认的
            </activation>
            <properties>
                <build.profile.id>bj</build.profile.id>   //变量，可用${build.profile.id}来调用
            </properties>
            <build>
                <filters>
                    <filter>profiles/${build.profile.id}/config.properties</filter>  //要使用的文件
                </filters>
                <resources>
                    <resource>
                        <filtering>true</filtering>
                        <directory>src/main/resources</directory> //要替换的目录
                        <includes>
                            <include>*.properties</include>    //被替换的文件类型
                        </includes>
                    </resource>
                    <resource>
                        <filtering>false</filtering>
                        <directory>src/main/resources</directory>
                    </resource>
                </resources>
            </build>
        </profile>
        <profile>
            <id>local</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <build.profile.id>local</build.profile.id>
            </properties>
            <build>
                <filters>
                    <filter>profiles/${build.profile.id}/config.properties</filter>
                </filters>
                <resources>
                    <resource>
                        <filtering>true</filtering>
                        <directory>src/main/resources</directory>
                        <includes>
                            <include>*.properties</include>
                        </includes>
                    </resource>
                    <resource>
                        <filtering>false</filtering>
                        <directory>src/main/resources</directory>
                    </resource>
                </resources>
            </build>
        </profile>
    </profiles>

  可以使用config.properties中的值替换src/main/resources下所有后缀是properties的相同key的值
