首先去http://www.jspsmart.com下載jspSmartUpload.zip,解壓縮后將文件放在WEB-INF/classes/下（目前這個(gè)網(wǎng)站已經(jīng)被關(guān)閉）
本地下載
下面是演示。SmartUpLoad只有一個(gè)構(gòu)造函數(shù)。即public
SmartUpload在jsp中直接使用javaBean來生成一個(gè)SmartUpLoad的對象
<jsp:useBean
id="mySmartUpload" scope="page"
class="com.jspsmart.upload.SmartUpload"/>
下面是演示。其中方法都是有注釋的
