NEW API Link

Hi I am trying to add new table and create new api, i have searched to forum and followed some,
so far i have created /api/form
and created the model with getters and setters
created the url path for the API but not sure how can i get this to save into Database.
i think I am missing the service that connect the db with model.
I am new to Java, i used php previously, can anyone advice me how can i get this api path to save data to database and i will contribute this new feature through github.
