在RememberMeServices-Grails/Spring安全性中获取会话

我有一个类，它实现了RememberMeServices和LogoutHandler接口。我已打开会话固定，并可以选择将会话创建为true。当我尝试使用LoginAccess方法获取会话时

RequestContextHolder.currentRequestAttributes（）.getSession（）

我听到一个错误说

如何获取当前会话？

没有看到您的实际代码，也不知道您正在使用的grails版本。在我听来，你是想从某个控制器的“LoginSucess”方法获取会话？如果是这样的话，会话是否只是作为“会话”提供，而不调用RequestContextHolder之类的东西？您应该像“请求”对象一样访问它，并像地图一样将数据塞入其中：

session.foo = "bar"
