如何将ASObject转换为JAVA对象

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)
