用JspSmart组件实现文件上传和下载

由于www.jspsmart.com停止运营，我将其源代码写出来。JspSmart的源代码只有五个类，分别为File,Files,Request,SmartUploadException和主要业务类SmartUpload,软件包名为com.jspsmart.upload

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;

// Referencedclassesofpackagecom.jspsmart.upload:
// SmartUploadException,SmartUpload
