FlexSession简单应用

package com.test;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import flex.messaging.*;
public class GETSESSION {

public GETSESSION() {
// TODO Auto-generated constructor stub
}
public void setSession(String atr,Object val){
HttpServletRequest request = FlexContext.getHttpRequest();
HttpSession session = request.getSession();
session.setAttribute(atr,val);
}
public Object getSession(String atr){
HttpServletRequest request = FlexContext.getHttpRequest();
HttpSession session = request.getSession();
return session.getAttribute(atr);
}

}

PS1:我的remoting-config.xml:

<destination id="gethttpsession">
<properties>
<source>com.test.GETSESSION</source>
<scope>application</scope>
</properties>
</destination>

PS2:返回的OBJECT如果想要与AS3的OBJECT转化的话这个类要实现序列化(Serializable),还必须有get set方法,maybe flex access to the object with this javacode

mxml:
