Flex 處理服務(wù)器端傳來的數(shù)據(jù)第1/2頁

更新時間：2009年08月09日 00:43:18 作者：

對于Java端返回的各種Java類型的對象，F(xiàn)lex中能否有相應(yīng)的數(shù)據(jù)類型來映射。這是Flex與服務(wù)器通信使用remoteObject的關(guān)鍵。

下面我舉個較為全面的例子，先看整個項目的結(jié)構(gòu)，服務(wù)器端使用BlazeDs，結(jié)構(gòu)為

客戶端使用flex builder 3開發(fā)，結(jié)構(gòu)就遵循flex builder 3標(biāo)準(zhǔn)

client.mxml為
