Maven 配置打不同環境的版本包

     Maven 提供了豐富的插件，本文說明了maven 插件打包的步驟：

     pom.xml 文件如下：

<profiles>
   <!-- dev環境 -->
   <profile>
      <id>dev</id>
      <build>
         <filters>

</profiles>

params.dev.properties 是指在項目里配置的開發環境數據鏈接

params.uat.properties 是指在項目里配置的測試環境數據鏈接

params.pro.properties 是指在項目里配置的生產環境數據鏈接

params.properties 是指上面三個指定的打包的數據鏈接
