您好我正在使用 Spring Security 3.0.5 和 Spring Framework 3.0.6。我已经按照文档配置了并发。它不工作。我从浏览器会话登录到应用程序，然后尝试从同一浏览器中的另一个选项卡再次登录 - 它让我登录而不是拒绝尝试。

这是我的安全配置文件：

添加<beans:property name="exceptionIfMaximumExceeded" value="true" />到org.springframework.security.web.authentication.session.ConcurrentSessionControlStrategybean 定义。如果超出允许的会话，它将抛出异常。

这会产生副作用。假设用户登录浏览器并关闭清除会话数据的浏览器。然后用户必须等待服务器中的会话过期才能再次登录。除非您有明确的要求，否则我更喜欢您现有的配置。
