Maven根据不同个环境打包, 获取不同的配置文件等等_打war包区分各个环境配置文件

打war包区分各个环境配置文件
这段时间接触Maven, 发现还是个不错的东西, 我在OpenShift申请了一个账号, 准备自己做一个自己的网站, 它默认是Maven管理的, 也可以自己用其他的.但是我要打war, 然后发布. 我本地的测试配置文件 与 线上的配置不一样, SB的做法就是每次复制粘贴, 这太....所以, 我必须要在本地的IDEA里面一样, 需要谁作为我的资源文件就要作为的我资源文件, 那就方便了, 找了很多的BLGO, 说的很好, 就是琳琳碎碎的. 还不如给我一个pom.xml了.以至于我一直没有跑起来, 或者他们的碎片就是不完整的, 自己折腾了半天, 并且自己测试, 上线, 都OK. ...

其中, 我们注意的地方: 我解释一下:

             <properties>
                 < package .environment>local</ package .environment>

             <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;

                     <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;

这里就是war的插件了, 

?
1
${ package .environment}

就是动态指定文件夹了.

?
1
<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~
