从 URL 中删除 jsessionid

Question

我正在使用以下技术开展一个项目：

• 弹簧
• ShiroFilter
• 漂亮的面孔
• 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。

Answer 1

对于 tomcat 7，将此添加到 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，在你的 context.xml 中添加 disableURLRewriting="true"

• Tomcat 7 和 ServletFilter 已经讨论过

• 或以编程方式：

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

Answer 4

您可以将该设置添加到您的 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，您将希望将其从 Tomcat 中取出，但如果您还没有设置 cookie，Shiro 将其附加到重定向的末尾仍然会有问题。关于这个问题有两张未解决的票：

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

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

我试图让 Tuckey 的 URL Re-write 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() 并因此触发出站规则。我能够使用以下两条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，但并不能完全解决问题，因为会话 ID 是在 URL 上发送的，并且在没有它的情况下被重定向到该位置。如果它根本不出现就更好了。

更新：

SHIRO-360 和 SHIRO-361 已修复，修复在 Shiro 1.3.0 中。根据 SHIRO-361 中的 Brian Demers：

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

注意：如果用户禁用了 cookie，如果禁用，他们将无法登录。

Answer 6

如果您不使用 Servlet 3.0，您也可以使用 PrettyFaces 重写规则来实现这一点：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);
