Play2“包括”指令覆盖配置替换

问题描述

限时删除！！

我的play2.1.0应用程序中有以下conf文件

• application.conf


• override.dev.conf


• override.qa.conf


• override.prod.conf

在application.conf文件中有一个 application.mode 属性，它将有一个dev / qa / prod值。

application.conf还有一行将env / mode特定的conf文件包含为覆盖。

原因：
要在env / mode特定的conf文件中具有覆盖属性。

推荐：

尝试：

1. 能够为另一个属性取代，但不能为包括像这样

   
   
   

   my.prop =override。$ {？application.mode}。conf

   
   
   

   到 override.dev.conf if application.mode = dev




2. 如果我有下面的东西它不工作，我想它的预期的文档参考。

   
   
   

   includeoverride。$ {？application.mode}。conf

   
   
   

   覆盖在名为 override.dev.conf

的文件中的道具

问题：

• 这应该是未来的增强功能还是预期的结果？ li>
  
• 实现我想要的其他方法是什么？

任何帮助将非常感激。

解决方案

我更喜欢覆盖。它是在Scala中完成，但也应该可以在Java中做。

它可以以非常好的方式重载配置，而不需要启动应用程序命令行参数，您仍然使用播放，播放开始等启动应用程序。

如果您将 override.qa.conf 更改为 override.test，您应该能够使用此方法。 conf

所有共享设置 application.conf ，然后在其他选项中覆盖。

I have following conf files in my play2.1.0 application

• application.conf
• override.dev.conf
• override.qa.conf
• override.prod.conf

And there is a application.mode property in the application.conf file which will have either one of dev/qa/prod values.

application.conf also has a line to include env/mode specific conf files as override. This is what is not working with substitution.

Reason:To have the override properties in the env/mode specific conf files.

Referred:http://www.playframework.com/documentation/2.0/Configuration

Tried:

1. Able to get the substitution done for another property but not for include like this

   my.prop="override."${?application.mode}".conf"

   The above outputs to override.dev.conf if application.mode=dev

2. If I have something like below its not working and i suppose its what is expected as per the documentation reference.

   include "override."${?application.mode}".conf"

   Expected the above to include/override props in a file named override.dev.conf

Question:

• Should this be a future enhancement or this is what is expected out of it?
• What are the other ways to implement what I wanted?

Any help would be really appreciated.

解决方案

I prefer to override the GlobalSettings.onLoadConfig as described in PlayFramework 2 load different config according to current mode. It is done in Scala but it should be possible to do in Java as well.

It lets you overload configurations in a very nice way without the need to start the application with command line arguments, you still start the app with play run, play start, etc.

You should be able to use this method if you change your override.qa.conf to override.test.conf since qa is not a known mode in Play.

All shared settings in the application.conf and then override in the other ones.
