Put a spring boot project in a cms

I created a project in java using spring boot, it's a web application that allow user to marshall and unmarshall some xml code.

I was wondering if it's possible to put it in a cms preserving his functionality (I never used a cms, so I don't know how it works and I can't understand if it's possible by the information given by any), and if the answer is yes, how. Or if there's a way to allow an user to modify just the text of a jsp (without seeing the code) in the project, also I'm searching for this solution and find nothing.

Thanks in advance for any advise.
