flexhttpsession.java

spring+Jsf+hibernate集成实例

package com.QualityTrack.Version;

public class FlexHttpSession {
	
	/*
	 * 
	 
	     //在java类中导入以下包
	    import javax.servlet.http.HttpServletRequest;
	    import javax.servlet.http.HttpSession;
	    import flex.messaging.*; //关键是这个包
	      然后在类中这样写代码
	    public void getSession(){  //函数名自定义什么都行
	          HttpServletRequest request = FlexContext.getHttpRequest();//通过这个函数就能得到httprequest对像
	            HttpSession session = request.getSession(); //这样就得到了httpsession
	            session.setAttribute("a","b");
	          以下就和普通操纵session一样了
		}
	  至于为什么flex可以这样做,可能web.xml配置文件里有一些设置,但是建工程的时候都生成了,我配置文件里面什么都没动,具体原理我不太懂
