symbolische Links tomcat 8 Verzeichnisressourcen

Question

würde Ich mag JSP Symlink Verzeichnisse unter Tomcat 8.
Es funktionierte auch in Tomcat 7 auf diese Weise:

<Context allowLinking="true"> 

aber scheint die Tomcat 8 fiel diese Funktion, und Es begann die Ressourcen

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

Mein Beispiel Nutzung:

ROOT/jspdirectory -> linksto ->/var/tmp/realplaceofjspfiles/

Eine schlechte Konfiguration:

ROOT/META-INF /context.xml:

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

Es ist für mich fiel th Ausnahme ist:

ich die "internalPath" hier zu sehen:

Answer 1

Es scheint, dass Sie eine separate "webAppMount" Eigenschaft benötigen.

<?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> 

Das funktionierte für mich. Es ist in meiner Web-App META-INF/context.xml

Answer 2

Tomcat aktivieren symbolische Links für den Zugriff auf die folgenden Schritte aus:

$CATALINA_HOME/conf/context.xml 

Tomcat 7:

<Context allowLinking="true"> 
... 

Tomcat 8:

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

NICHT UNTER WINDOWS (oder einem anderen Dateisystem, bei dem die Groß-/Kleinschreibung nicht berücksichtigt wird), , da es die Überprüfung der Groß- und Kleinschreibung deaktiviert, so dass neben anderen Sicherheitsproblemen der JSP-Quellcode offengelegt werden kann.
