关键代码：

<profiles>
        <profile>
            <id>local</id>
            <properties>
                <package.environment>local</package.environment>
            </properties>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
        <profile>
            <id>product</id>
            <properties>
                <package.environment>product</package.environment>
            </properties>
        </profile>
    </profiles>

　　    这里就是不同的resources文件夹, 我这里只区分本地 产品; 设置为true的就是默认被激活的. 所以后面打包默认就是本地;

<resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <excludes>
                    <exclude>local/*</exclude>
                    <exclude>product/*</exclude>
                    <exclude>public/*</exclude>
                </excludes>
            </resource>
        </resources>

　　这里就是我的资源文件, public里面存放我的公用的, 比如Spring的配置文件, 就是本地与产品都一样的;local 与 product一看就知道了;

                            <targetPath>WEB-INF/classes</targetPath>

                        </resource>
                        <resource>
                            <directory>src/main/resources/public</directory>
                            <targetPath>WEB-INF/classes</targetPath>
                            <filtering>true</filtering>
                        </resource>
                        <!--<resource>-->
                            <!--<directory>${project.build.directory}/classes</directory>-->
                            <!--<includes>-->
                                <!--<include>**/*.properties</include>-->
                                <!--<include>**/*.xml</include>-->
                            <!--</includes>-->
                        <!--</resource>-->
                    </webResources>
                </configuration>
            </plugin>

　　这里就是war的插件了, 

${package.environment}

就是动态指定文件夹了.

<filtering>true</filtering>

这里一定需要设置为true才行.

然后就差不多了. 最后执行 mvn clean ; mvn compile; mvn package; 这里是Maven的生命周期, 其他介绍的文章太多了, 我就不再具体讲. 如果说我要打product的war包; 

mvn clean ; mvn compile; mvn -Pproduct package; 

那就激活了product 的资源文件;

就这样子, 很简单吧~
