This is a sample java project in which we have performed all the CRUD operation on Json Data using REST endpoints.

We have used MongoDB as DataBase in this experiment. MongoDB is a free and open-source cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with schemas

We have also performed file uploads using various methods supported by Play Framework. We have also explored mongo GRIDFS which is mainly used to save files into MongoDB.

Endpoints:-
