如何将ASObject转换为JAVA对象

来源：互联网发布：廊坊php待遇编辑：程序博客网时间：2024/06/05 09:34

我试过不建立As对象也可以实现java对象的转换
flex相关jar包中java对象转换到AS对象中间有个ASObject(一个java类继承MAP)他把java类的属性读出放到其Map映射返回到flex前台就是ASObject了
就是说你new 一个ASOBject 按照MAP设置好属性,值到前台就是一个ASObject对象可以直接用该对象取值

总结就是:
flex对象传到java(如果没经过绑定强转)都看成ASObject 其为一个Map型集合可以通过类属性充当Key从中取值
flex中集合传来都看成flex.messaging.io.ArrayCollection该集合实现List接口传递给flex flex可以直接识别
flexObjec <--> ASObject(flex.messaging.io.amf.ASObject) <---> javaObject
flexArray <--> ArrayCollection(flex.messaging.io.ArrayCollection) <---> javaArray(List)

例:我查询数据库返回ASObject到flex
import flex.messaging.io.ArrayCollection;

public ArrayCollection getSqlData(String sql)
    {
       ArrayCollection asList = new ArrayCollection(jdbc.getSqlData(sql));
        return asList;
    }
这是我自己写的一个类尝试转换的时间久远那些方法测试过没我也忘了(基于Spring相关类)
