在struts下有两种session的操作方式，分别是：
1. 通过ActionContext的getSession方法获取
package cn.com.suboo.test; import java.util.Map; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; public class SessionTest1 extends ActionSupport { public String execute() { //用ActionContext的getSession方法获取session ActionContext actionContext = ActionContext.getContext(); Map session =actionContext.getSession(); //往session里添加一条纪录 session.put("USER_NAME","user"); return SUCCESS; } }2. 在Action实现org.apache.struts2.interceptor.SessionAware接口
package cn.com.suboo.test; import java.util.Map; import org.apache.struts2.interceptor.SessionAware; import com.opensymphony.xwork2.ActionSupport; public class SessionTest extends ActionSupport implements SessionAware { private Map session; //setSession方法，设置session public void setSession (Map session) { this.session = session; } public String execute() { //往session里添加一条 this.session.put("USER_NAME","user"); return SUCCESS; } }3. 在JSP里获取session的方法
<%@ page contentType="text/html;charset=UTF-8" %> <%@page pageEncoding="utf-8" %> <%@taglib prefix="s" uri="/struts-tags" %> <html> <head> <title>Session Test</title> </head> <body> <h1><s:property value="#session.USER_NAME"/></h1> <h1></h1> </body> </html>注销session的方法
// 注销 public String logout() throws Exception { ((org.apache.struts2.dispatcher.SessionMap<String, Object>) this.session).invalidate(); return SUCCESS; }
