JspSmartUpload Tutorial: File Upload in JSP

JspSmartUpload is a Java class library used for implementing file uploads in JSP pages. Here is a brief overview of how to use JspSmartUpload:

1. Firstly, add the JspSmartUpload.jar file to your project and import the class library in your JSP page.

<%@ page import="com.jspsmart.upload.SmartUpload" %>

1. In the JSP page for handling file uploads, instantiate a SmartUpload object.

SmartUpload su = new SmartUpload();

1. Specify the path for saving uploaded files:

su.initialize(pageContext);
su.setAllowedFilesList("jpg, gif, png");
su.setDeniedFilesList("exe, dll");
su.upload();
su.save("upload");

1. Get the uploaded files.

File file = su.getFiles().getFile(0);

1. You can obtain information about a file, such as its name and size, through the file object.

String fileName = file.getFileName();
long fileSize = file.getSize();

file.saveAs("保存路径");
