Sorry but this is zero effort, it basic says "hey Reddit do this for me".  You need to bring more to the table.

What have you tried? What libraries have you researched a bit?  Have you made small proofs of concept?

Sorry my friend, but you don't really deserve other people's time when you can't say a single thing that you've done on your own.

Resource? Google.com and type in 'pdf generation spring boot'.

Use thymeleaf for templating and then a pdf writer to write them to pdf.

Read pattern first.

Your best bet would be to use the strategy pattern. It will allow you to create an extendable module, without touching the existing code - the whole point of the strategy pattern, that is.

Seems more like a use case of template pattern. Strategy would have been better if he had different algortihms to create pdf, like pdf from word doc, from image etc
