Suggestion: Could you add the initial SQL file with data? It will save some time.

Here are my SQL statements for the jwtDemo:

INSERT INTO `roles` (`id`, `name`) VALUES (1, 'ROLE_ADMIN');
INSERT INTO `roles` (`id`, `name`) VALUES (2, 'ROLE_USER');

INSERT INTO `users` (`id`, `email`, `name`, `password`, `username`) VALUES (1, 'john@gmail.com', 'John', '$2a$12$HeVk0EIlGIWq5hNKf2Ziq.9iTs2cAHUFaZG.8s7ahbPto.0gApDti', 'john');
INSERT INTO `users` (`id`, `email`, `name`, `password`, `username`) VALUES (2, 'Lakshitha@gmail.com', 'Lakshitha', '$2a$12$UD73VrZpFcVI1M.Mrfw/bOSNEG.FgrFpCKDcpDRHzKA1awE4nguqG', 'lakshitha');

INSERT INTO `users_roles` (`user_id`, `role_id`) VALUES (1, 1);
INSERT INTO `users_roles` (`user_id`, `role_id`) VALUES (2, 2);
