HttpSessionBindingListener (Java EE 5)

使对象在被绑定到会话或从会话中取消对它的绑定时得到通知。该对象通过 HttpSessionBindingEvent 对象得到通知。这可能是 servlet 编程人员显式从会话中取消绑定某个属性的结果（由于会话无效，或者由于会话超时）。

英文文档：

Causes an object to be notified when it is bound to or unbound from a session. The object is notified by an HttpSessionBindingEvent object. This may be as a result of a servlet programmer explicitly unbinding an attribute from a session, due to a session being invalidated, or due to a session timing out.
