hibernate composite key

@Entuty
@Table(name="sample")
public class SampleRecord {

    @Column(name = "id")
    private long id;

    @Column(name = "name")
    private String name;

    //abridgement
}

Exception in thread "main" org.hibernate.AnnotationException: No identifier specified for entity: com.sample.jpa.SampleRecord

It seems that you have to specify @ Id when using @ Entity

@Embeddable
@Table(name="sample")
public class SampleRecord {

    @Column(name = "id")
    private long id;

    @Column(name = "name")
    private String name;

    //abridgement
}

When I tried using @Embeddable, I was able to do it without a compilation error.
