Solution
The @GeneratedValue annotation in Hibernate is used to automatically generate the primary key value. It's typically used in conjunction with the @Id annotation on the field that represents the primary key of the entity. This annotation can take two parameters: strategy and generator. The strategy parameter is used to define the primary key generation strategy such as AUTO, IDENTITY, SEQUENCE, and TABLE. The generator parameter is used to refer to the name of a primary key generator.
