Question

HI我正在尝试实现Spring Security：并发会话控制一次限制一个会话。我看到我只需要

<http>
  ...
   <session-management>
     <concurrency-control max-sessions="1" />
   </session-management>
</http>

我从参考http://docs.spring.io/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-config得到了这个。我遇到的问题是我收到此错误，说“配置问题：无法建立AuthenticationEntryPoint。请确保您通过命名空间配置登录机制（例如表单登录）或指定自定义AuthenticationEntryPoint 'entry-point-ref'属性“我不需要在配置中使用登录页面。我看到其他帖子，但我找不到解决这个问题的方法。请帮我解决这个问题。我将在下面发布我的代码。
