  smartupload是什么 jspsmart是什么。jspSmartUpload是一款组件,用来对JSP进行程序开发过程中上传下载用的。而且还能支持下载中文名字的文件,非常简单方便,今天小编就分享下jspSmartUpload的组件源码给大家,希望大家喜欢。


  JspSmart之upload组件源码主要包括了5个java文件


  File.java


  import java.io.ByteArrayInputStream;


  import java.io.FileOutputStream;


  import java.io.IOException;


  import java.math.BigInteger;


  import java.sql.ResultSet;


  import java.sql.SQLException;


  import javax.servlet.ServletException;


  // Referenced classes of package com.jspsmart.upload:


  // SmartUploadException, SmartUpload
