包路径：javax.servlet.http.HttpSession
类名称：HttpSession
方法名：removeAttribute

HttpSession.removeAttribute介绍

[英]Removes the object bound with the specified name from this session. If the session does not have an object bound with the specified name, this method does nothing.

After this method executes, and if the object implements HttpSessionBindingListener, the container calls HttpSessionBindingListener.valueUnbound. The container then notifies any HttpSessionAttributeListeners in the web application.
[中]从此会话中删除与指定名称绑定的对象。如果会话没有使用指定名称绑定对象，则此方法不执行任何操作。
执行此方法后，如果对象实现HttpSessionBindingListener，容器将调用HttpSessionBindingListener.valueUnbound。然后容器通知web应用程序中的任何HttpSessionAttributeListener。
