Hibernate Annotation:-
Annotation is used to change the behavior of a class , method, and data member of the class using a predefined attribute.
Without using the hibernate mapping file we can map the database table using an annotation class.
The annotation will be defined under POJO Class.
@Table:- this annotation is used to map database table from class
@Column:- this annotation is used to map database table column
@id:- it is used to define the primary key column of the table
@Entity:- It is used to provide annotation to implement database schema
if we use the Annotation Mapping class then we will define the mapping class under the hibernate.cfg.xml file
All hibernate annotations exist under javax.persistent package. means javax.persistence jar file should be present in your project lib folder.
