Question

我尝试在Spring security 3.2中实现并发控制。我使用form-login进行身份验证。这是我的security.xml

听众

<listener-class>
org.springframework.security.web.session.HttpSessionEventPublisher
</listener-class>

包含在我的web.xml中。

我strat app，在不同的浏览器中运行，登录两个，但我有2个活动。似乎并发控制并不起作用。

如何使用form-login实现并发控制？

在之前的版本中我只使用了

<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。

Answer 1

SessionRegistry使用UserDetails的equals（）/ hashCode（）来查找同一用户的会话。我有自定义UserDetails，所以我必须实现这些方法并恢复以前的配置。

Spring安全并发控制不起作用
