从URL中删除jsessionid

Question

我正在使用以下技术开展项目：

• 弹簧
• Shirofi lter
• PrettyFaces
• Tomcat服务器

当我在tomcat服务器上部署它时，我在URL的末尾添加了一个"JSESSIONID 456jghd787aa"。

我试图解决这个问题，但我无法做到这一点。

Answer 1

对于tomcat 7，将其添加到web.xml

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

Answer 3

• Tomcat 6，在context.xml中添加disableURLRewriting =“true”
• 已经讨论过Tomcat 7和ServletFilter
• 或以编程方式：

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

Answer 4

您可以将此设置添加到http标记中，如下所示：

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

Answer 5

正如其他人所建议的那样，你会想要把它从Tomcat中取出来，但是如果你还没有设置cookie，那么你仍然会遇到Shiro在重定向时将其附加到最后的问题。这个问题有两张打开的门票：

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

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

我试图让Tuckey的URL重写工作，并在一段时间后取得了部分成功。问题是Shiro没有调用response.encodeURL（），因此会跳出出站规则。我能够使用以下两个规则重定向入站请求以删除会话ID：

<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>

这至少使它不会显示在浏览器中，但它并没有完全解决问题，因为会话ID是在URL上发送的，并且重定向到没有它的位置。如果它从未出现过会更好。

更新：

SHIRO-360和SHIRO-361已经修复，修复程序在Shiro 1.3.0中。根据SHIRO-361的Brian Demers的说法：

设置sessionManager.sessionIdUrlRewritingEnabled = false以禁用向URL附加JSESSIONID。

注意：如果用户已禁用cookie，则如果禁用cookie，则无法登录。

Answer 6

如果你没有使用Servlet 3.0，你也可以使用PrettyFaces Rewrite Rule来实现这个目标：http://ocpsoft.org/support/topic/url-rewrite-removing-the-jsessionid-from-the-url#post-410

Answer 7

Jetty WebappContext：

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