Tomcat的context.xml文件，有没有一个hiearchy？ [英] Tomcat context.xml files, is there a hiearchy?

问题描述

我想在Tomcat5上运行的应用程序中使用符号链接。感谢另一个StackOverflow问题的帮助，我能够做到
在

I am trying to use symbolic links in one of the applications I have running on Tomcat5. Thanks to some help from another StackOverflow question I was able to do it by creating a context.xml file in

/ ... myapplication / META-INF / context.xml

/...myapplication/META-INF/context.xml

我现在试图在生产服务器上实现这一点。但是，还有其他应用程序正在运行。还有另一个上下文文件

I am now trying to implement this on a production server. However, there are other applications running on it. And there is another context file

/ ... tomcat / conf / context.xml

/...tomcat/conf/context.xml

我这些是将服务器范围的配置设置到所有应用程序。如果我在conf / context.xml文件中允许链接，我的符号链接工作。如果我不在conf / context.xml中allowLinks，我的应用程序的符号链接不工作，即使我已经允许他们在META-INF / context.xml

It seems to me these are setting configurations server-wide to all applications. If I allowLinks in the conf/context.xml file, my symbolic links work. If I don't allowLinks in conf/context.xml, my application's symbolic links do not work, even though I have allowed them in the META-INF/context.xml

我的问题是，conf / context.xml是否控制所有应用程序？如果我想要符号链接仅在一个应用程序中工作，我需要删除conf / context.xml并为每个应用程序创建新的上下文文件？还是有一种方法，我只能在myapplication中允许符号链接？

My question is, does the conf/context.xml control all applications? If I want symbolic links to work only in one application, do I need to remove the conf/context.xml and create new context files for each application? Or is there a way I can allow symbolic links in myapplication only?

推荐答案

请参阅我的回答到哪个Tomcat 5上下文文件优先问题。

关于您的特定 allowLinks 问题， conf / context.xml 中的值默认为优先。如果你在 conf / context.xml 中没有说什么，默认值为 conf / context中使用config / context.html＃Standard％20Implementationrel =nofollow noreferrer> allowLinks =false .xml 。

Regarding your specific allowLinks question, the value in conf/context.xml takes precedence by default. If you say nothing in your conf/context.xml, the default value is allowLinks="false" in your conf/context.xml.

如果您只想为 myapplication 在 META-INF / context.xml 中的< Context allowLinks =true...&因为 > c / conf / context.xml 设置将优先。

If you want to change it only for your myapplication, trying to say <Context allowLinks="true" ...> in your META-INF/context.xml will have no effect because normally the conf/context.xml setting will take precedence.

但是，如果您在<$ c $中表示< Context allowLinks =true override =true ...> c> META-INF / context.xml ，然后在 META-INF / context中的所有< Context> .xml 将最高优先级，覆盖 conf / context.xml 中的任何内容。

But, if you say <Context allowLinks="true" override="true" ...> in your META-INF/context.xml, then all your <Context> settings in META-INF/context.xml will be highest precedence, overriding anything in conf/context.xml.

最后，我建议使用 conf / Catalina，而不是 myapplication / WEB-INF / context.xml /localhost/myapplication.xml 文件。这种技术意味着你可以保持你的WEB-INF的内容清洁，这是你的webapp的胆量 - 我不喜欢冒险在我的webapp的胆量。 ： - ）

Finally, instead of a myapplication/WEB-INF/context.xml file, I recommend using a conf/Catalina/localhost/myapplication.xml file. This technique means you can keep the contents of your WEB-INF clean, which is the guts of your webapp -- I don't like to risk mucking about in the guts of my webapp. :-)
