Remove jsessionid from URL

问题

I'm working on a project with the following technologies:

Spring
ShiroFilter
PrettyFaces
Tomcat server

While I'm deploying it on tomcat server, I'm getting a "JSESSIONID 456jghd787aa" added at the end of the URL.

I was trying to resolve this but I'm not able to do that.

回答1:

For tomcat 7 add this to web.xml

<session-config>
  <!-- Disables URL-based sessions (no more 'jsessionid' in the URL using Tomcat) -->
  <tracking-mode>COOKIE</tracking-mode>
</session-config>

回答2:

The following filter may solve your problem (from http://randomcoder.org/maven/site/randomcoder-website/cobertura/org.randomcoder.security.DisableUrlSessionFilter.html)

package com.companyname.projectname.web.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponseWrapper;
import javax.servlet.http.HttpSession;

回答3:

Tomcat 6, add disableURLRewriting="true" in your context.xml
Tomcat 7 and ServletFilter have already been discussed
Or programmatically :

servletContext.setSessionTrackingModes(EnumSet.of(SessionTrackingMode.COOKIE));

回答4:

You can add that settings into your http tag as follows:

<http auto-config="false" disable-url-rewriting="true">

回答5:

You'll want to take it out of Tomcat, as others have suggested, but you'll still have problems with Shiro appending it to the end on redirects if you don't have a cookie set yet. There are two open tickets on the problem:

https://issues.apache.org/jira/browse/SHIRO-360

https://issues.apache.org/jira/browse/SHIRO-361

I tried to get Tuckey's URL Re-write to work and had partial success after a while. The problem is Shiro doesn't call response.encodeURL() and therefore trip the outbound rules. I was able to redirect inbound requests to remove the session id with these two rules:

<rule>
    <note>Remove jsessionid from embedded urls - for urls WITH query parameters</note>
    <from>^/(.*);JSESSIONID=.*[?](.*)$</from>
    <to type="redirect">/$1?$2</to>
</rule>

<rule>
    <note>Remove jsessionid from embedded urls - for urls WITHOUT query parameters</note>
    <from>^/(.*);JSESSIONID=.*[^?]$</from>
    <to type="redirect">/$1</to>
</rule>

That at least makes it not show up in the browser, but it doesn't completely solve the problem, because the session ID was sent on the URL and the redirected to the location without it. It would be better if it never showed up at all.

UPDATE:

SHIRO-360 and SHIRO-361 have been fixed and the fixes are in Shiro 1.3.0. According Brian Demers in SHIRO-361:

Set sessionManager.sessionIdUrlRewritingEnabled = false to disable appending JSESSIONID to the URL.

NOTE: if a user has disabled cookies, they will NOT be able to login if this is disable.

回答6:

If you are not using Servlet 3.0, you can also achieve this using a PrettyFaces Rewrite Rule: http://ocpsoft.org/support/topic/url-rewrite-removing-the-jsessionid-from-the-url#post-410

回答7:

Jetty WebappContext:

Set<SessionTrackingMode> trackingModes = new HashSet<>();
trackingModes.add(SessionTrackingMode.COOKIE);
context.getSessionHandler().getSessionManager().setSessionTrackingModes(trackingModes);
