本文整理了Java中javax.servlet.http.HttpSession.setAttribute()方法的一些代码示例，展示了HttpSession.setAttribute()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。HttpSession.setAttribute()方法的具体详情如下：
包路径：javax.servlet.http.HttpSession
类名称：HttpSession
方法名：setAttribute

HttpSession.setAttribute介绍

[英]Binds an object to this session, using the name specified. If an object of the same name is already bound to the session, the object is replaced.

After this method executes, and if the new object implements HttpSessionBindingListener, the container calls HttpSessionBindingListener.valueBound. The container then notifies any HttpSessionAttributeListeners in the web application.

If an object was already bound to this session of this name that implements HttpSessionBindingListener, its HttpSessionBindingListener.valueUnbound method is called.

If the value passed in is null, this has the same effect as calling removeAttribute().
[中]使用指定的名称将对象绑定到此会话。如果同名对象已绑定到会话，则该对象将被替换。
执行此方法后，如果新对象实现HttpSessionBindingListener，容器将调用HttpSessionBindingListener.valueBound。然后容器通知web应用程序中的任何HttpSessionAttributeListener。
如果对象已绑定到此实现HttpSessionBindingListener的同名会话，则调用其HttpSessionBindingListener.valueUnbound方法。
如果传入的值为null，则这与调用removeAttribute()具有相同的效果。
