Dev Mode Or Production Mode

There are two Profiles in which service can run.

1. Dev Mode : In this mode, no authentication is required
2. Prod Mode: In this mode, first we have to authenticate by providing username/password. This mode uses JWT. The behaviour of the token can be controlled via following parameters : -Djwt.header=authorization -Djwt.expires_in=300 -Djwt.secret=queenvictoria. These parameters are present in application.properties also. a) jwt.header := The Key Name by which token will be present in the header b) jwt.expires_in := time in secs. c) jwt.secret = The Secret Key

Steps for code execution

1. Pull the code
2. Create a Postgres db with the name product-manager
3. Copy contents from data.sql and run the queries
