I have used the @CreatedBy, @CreatedDate, @LastModifiedBy, and @LastModifiedDate annotation on their respective fields. By using @MappedSuperclass,@EntityListeners i able to persist above columns.

But this is not working for the below case:

@MappedSuperclass

@EntityListeners(AuditingEntityListener.class)

public abstract class Auditable<U> {

    @CreatedBy

    protected U createdBy;

    @CreatedDate

    @Temporal(TIMESTAMP)

    protected Date creationDate;

    @LastModifiedBy

    protected U lastModifiedBy;

    @LastModifiedDate

    @Temporal(TIMESTAMP)

    protected Date lastModifiedDate;

}



@Entity

@Table(name = "tabel1")

@PrimaryKeyJoinColumn(name = "ID")

class A extends B {



    @Column(name = "NAME1", nullable = false)

    private String name1;

    @Column(name = "CONTENT1", nullable = false)

    private String content1;

}



@Entity

@Table(name = "tabel2")

public abstract class B extends Auditable{

    @Id

    @GeneratedValue

    @Column(name = "ID", nullable = false)

    private int id;

    @Column(name = "NAME", nullable = false)

    private String name;

    @Column(name = "CONTENT", nullable = false)

    private String content;

}

AuditorAwareImpl.java

public class AuditorAwareImpl implements AuditorAware<String>

{

    @Override

    public Optional<String> getCurrentAuditor()

    {

        return Optional.ofNullable("Saravanan");



    }



}

JpaAuditConfiguration.java

@Configuration

@EnableJpaAuditing(auditorAwareRef = "auditorProvider")

public class JpaAuditConfiguration

{

    @Bean

    public AuditorAware<String> auditorProvider()

    {



        return new AuditorAwareImpl();

    }

}

In the case, Entity B is populated with audit columns. But Entity A is not. Is there a way to populate Entity A or did i missed anything here..??

I added @Entity annotation to your classes:

@Entity

public class A extends B {



    @Id

    @GeneratedValue

    private Integer id;



    private String name;

    private String content;



}



@Entity

public class B extends Auditable<String> {



    @Id

    @GeneratedValue

    private Integer id;



    private String name;

    private String content;

}

Persistence config class (for Spring Boot):

@Configuration

@EnableJpaAuditing

public class PersistenceConfig {

}

Everything works perfectly!
