我尝试在Spring Security 3.2中实现并发控制。
我使用表单登录进行身份验证。
这是我的security.xml

<listener-class>
org.springframework.security.web.session.HttpSessionEventPublisher
</listener-class>
包含在我的web.xml中。
我分层应用程序,在不同的浏览器中运行,都登录,但是我有2个活动会话。似乎并发控制不起作用。
如何使用表单登录来实现并发控制?
在以前的版本中,我只是使用
<session-management>
<concurrency-control max-sessions="1" expired-url="/expired.html" error-if-maximum-exceeded="false" session-registry-ref="sessionRegistry" />
</session-management>
感谢您的任何建议。
最佳答案
SessionRegistry使用UserDetails的equals()/ hashCode()查找同一用户的会话。我有自定义的UserDetails,因此我必须实现此方法并还原以前的配置。
