Convert a form to PDF in Java

There are about three ways to search online: PDF template data fill, HTML code conversion PDF, borrow Wkhtmltopdf tool one. PDF template Data fill 1. Create a new word, make an empty form in Word that has the same layout as the form, and then save as pdf;2. Using the PDF Editing Tool, use the Prepare Form tool to set up a text box or image frame where dynamic data needs to be populated, and to get a good label name. 3. Insert the data into the PDF according to the label signature and export the PDF to the specified location.
