symlinking tomcat 8目录资源

Question

我想在Tomcat 8下使用符号链接JSP目录.
它在Tomcat 7中也可以这样工作:

    <Context allowLinking="true">

但似乎Tomcat 8放弃了这个功能,它开始使用资源

(http://tomcat.apache.org/migration-8.html#Web_application_resources).

我的示例用法:

ROOT/jsp目录 - > linksto - >/var/tmp/realplaceofjspfiles /

配置错误:

ROOT/META-INF/context.xml的:

<Context>
   <Resources allowLinking="true">
         <PreResources className="org.apache.catalina.webresources.DirResourceSet"   base="/var/tmp/realplaceofjspfiles" internalPath="jspdirectory"/>
    </Resources>
</Context>

它为我丢掉了这个例外:

我在这里看到了"internalPath":http:

Answer 1

要使Tomcat能够访问符号链接,请执行以下操作:

$CATALINA_HOME/conf/context.xml

雄猫7:

<Context allowLinking="true">
...

雄猫8:

<Context>
    <Resources allowLinking="true" />
...

不要在WINDOWS(或任何其他不区分大小写的文件系统)上执行此操作,因为它将禁用区分大小写检查,允许JSP源代码泄露以及其他安全问题.

看来您需要一个单独的“webAppMount”属性。

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/">
    <Resources>
        <PreResources
            className="org.apache.catalina.webresources.DirResourceSet"
            base="/FilePath/.../Resources"
            webAppMount="/resources"
            internalPath="/"/>
    </Resources>
 </Context>

这对我有用。它位于我的网络应用程序的 META-INF/context.xml 中
