在webapp中获取当前的svn修订版 [英] obtain current svn revision in webapp

问题描述

在java webapp中显示/使用修订号的最佳方法是什么？

what is the best way of displaying/using the revision number in a java webapp?

我们只使用ant来构建我们的.war存档，没有构建服务器或者这样的。我希望有一些我可以在资源文件中编写的$ ref，但只有在提交相关文件时才会更新。我需要全球。

we just use ant to build our .war archive, no buildserver or such. i'd hope there was some kind if $ref that i could write in a resource file, but this is only updated when the file in question is committed. i need it globally.

你会推荐什么？更新某些文件的提交后触发器？
自定义蚂蚁脚本？有没有更黑的方式这样做？
或者最好让我自己的版本号独立于svn。

what would you recommend? post-commit triggers that update certain files? custom ant scripts? is there a more non-hacky way of doing this? or it it better to have my own version number independent of svn.

编辑：很棒的建议！非常感谢你的答案！

edit: great suggestions! thanks a lot for the answers!

推荐答案

有几个Ant任务可以帮你完成。

SvnAnt任务来自底格里斯河是最古老的。

SvnAnt task from tigris is the oldest.

文件是这里 - 特别是看一下 info 元素，它将Subversion存储库的修订版号公开为一个Ant属性，它调用转。您可以使用正常的Ant替换机制将此值写入您的资源文件。

Documentation is here - in particular take a look at the info element which exposes the Subversion repository's revision number as an Ant property which it calls rev. You can write this value to your resouces file using the normal Ant substituion mechanisms.

有人还提出了 simillar（更简单）任务 - 从未使用它，但无法发表评论。

Someone has also put up a simillar (simpler) task on google code hosting - never used it though so can't comment.

如果你的构建中已经有Ant，那么这些对我来说似乎是最好的方式。

Either of these seem like the neatest way to me if you already have Ant in your build.
