In this tutorial we will see how to implement inheritance in hibernate.There are 3 ways in which you can implement inheritance in hibernate.In this post,we will see one of them

String name: The column name. Defaults to DTYPE . length: For string discriminator values, the length of the column. Defaults to 31. String Specifies the value of the discriminator column for entities of the given type. The DiscriminatorValue annotation can only be specified on a concrete entity class. If the
