In 3 hours, they asked me to do a spring boot application, that could respond at 3 REST call : - one for reading something in the database. - one for modifying something in the database. - one for inserting something in the database. For the call that should read in the database, it should wrap an error in case the resource you are asking is not present. When starting the application, it should automatically populate the database, just 1 table, with some data. When you are finish, you have to push your application in your githib account.
