Struts2的Action中取得Session、Request、Application对象的方法最常用的方法是：

private Map<String,Object> session;
private Map<String,Object> request;
private Map<String,Object> application;
session = ActionContext.getContext().getSession();
request = (Map) ActionContext.getContext().get("request");
application = ActionContext.getContext().getApplication();
session.put("name",	stu.getName());
request.put("age", stu.getAge());
application.put("name", stu.getName());

一、利用Struts2的标签

h2><s:property value="#session.name" /></h2>
<h3><s:property value="#request.age" /></h3>
<h4><s:property value="#application.name" /></h4>

二、利用Jsp中默认对象



<%=session.getAttribute("name") %>
<%=request.getAttribute("age") %>
<%=application.getAttribute("name") %>
