Can i mapping json from html to spring server without setters and getters?

I'm a beginner with web Spring and i have a generic eform project. So basicly the project is about a system that allows developer to adding or removing eform without changing the server side and database side. We use noSQL in the database side to avoid adding or removing table on SQL.

Is it possible to map a json without setters and getters? Cause it won't be a generic if i have to add or remove setters and getters everytime i'm adding and removing an eform.
