In .hbm file ,we can define composite primary key on the class properties.
for exam-

Class Person{

private String firstName;

private String lastName;

------------------
---------------------
---------------------
-------------------
}

has a composite primary key (firstName,lastName).We can map this composite key in .hbm file like this.

<composite-id>
<key-property name="firstName"/>
<key-property name="lastName"/>
</composite-id>



Is there any way in Hibernate annotation to map composite primary key on properties of same class. (without creating a new @Embeddable class, which will use as primary key).

i'm interested too

http://www.hibernate.org/hib_docs/annot ... ntity.html


You can define a composite primary key through several syntaxes:

annotate the component property as @Id and make the component class @Embeddable
annotate the component property as @EmbeddedId
annotate the class as @IdClass and annotate each property of the entity involved in the primary key with @Id




Hope this helps !!
