Editor to share with you what are the different ways to download JSP files, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. The most direct and easiest way to download a JSP file is to put the file address directly into a link on the html page. The disadvantage of this is that the path of the file on the server is exposed, and there is no other control over the file download (such as permissions). I won't write an example this time.

two。 On the server side, convert the file into an output stream, write it to response, take the file to the browser with response, and the browser prompts the user whether he is willing to save the file locally. (examples of downloading JSP files are as follows)

3. Since it is a JSP file download, there is another way to download JSP files is to use Applet to download files. But first, customers have to trust your Applet Mini Program. This program accepts the data stream sent by servlet and writes it locally.
