"Java" Itext generate PDFs from templates (including pictures and tables)

1, import the required jar package: Itext-asian-5.2.0.jar Itextpdf-5.5.11.jar.

2. New Word document, create template, save file as PDF, open edit with Adobe Acrobat DC, click "Prepare form" on the right and click "Start"

3. In the space where you need to insert the data, right click, click "Text Field", drag and drop the text field to the location you want, change the domain name as the variable name you passed in.

4. Save the file and put the file in the project. Generate the PDF code as follows:
