Java Spring Boot - JPA - Hibernate - H2 - Entities Inheritance Mapping - Single Table Strategy

In the first place we will configure database connection. Later in the video we will learn how to use inheritance together with JPA and Hibernate in Java Spring Boot application. We will create abstract super class (parent class) and then two sub-classes (child classes) which will inherit all of the properties and mapping information from parent class. We will use @Inheritance annotation to specify strategy which we will use. This time it will be SINGLE_TABLE strategy. Because of that we will also have to define information about our discrimnator column using @DiscrimnatorColumn annotation. Moving forward we will also define @DiscrimnatoValue annotations on our sub-classes. Thanks to that we will be able to distinguish persisted objects entries in the database. In our sub-classes we will also use @Enumerated annotation to learn how to persist enums. In the final stage we will learn how to use inheritance in case of repositories which we will use to persist and delete our entities from the database. We will track everything using H2 web console. Keep coding!
