Hibernate Annotation

 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

<mapping class="packagename.Pojoclassname" />

All hibernate annotations exist under javax.persistent package. means javax.persistence jar file should be present in your project lib folder.
