My Sql + Spring Boot JPA - One to many, many to one example

This is a simple spring boot JPA (hibernate) example. It will demonstrate how one to many, many to one mapping can be done

Below are the tables created in MySQL

create table department
 department_id int not null auto_increment,primary key (department_id),
 department_name  varchar(50) not null

create table employee
 employee_id int not null auto_increment, primary key (employee_id),
 employee_name varchar(50) not null, 
 department_id int not null, foreign key (department_id) references department(department_id)
