@CreatedBy @LastModifiedBy annotations are not working

When ever I create a any user that needs to be taken automatically who has created the User with the @CreatedBy annotation and when I manupulate any thing thats needs to be taken automatically with the annotation @LastModifiedBy. But this is not working now. What may be the reason?

This is my entity class

@Slf4j
@Getter
@Setter
@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public abstract class AbstractAuditingEntity implements Serializable {

    private static final long serialVersionUID = 1L;

    @CreatedBy
    @Column(name = "created_by" , nullable = false, length = 50, updatable = false) 
    @JsonIgnore
    private String createdBy;
    @CreatedDate
    @Column(name = "created_date", updatable = false)
    @JsonIgnore
    private Instant createdDate = Instant.now();
    @LastModifiedBy
    @Column(name = "last_modified_by", length = 50)
    @JsonIgnore
    private String lastModifiedBy;
    @LastModifiedDate
    @Column(name = "last_modified_date")
    @JsonIgnore
    private Instant lastModifiedDate = Instant.now();
    @Transient
    public <T> T getView(Class<T> viewClass) {
        try {
            T view = viewClass.getDeclaredConstructor().newInstance();
            BeanUtils.copyProperties(this, view);
            return view;
        } catch (InstantiationException | IllegalAccessException | NoSuchMethodException | InvocationTargetException e) {
            log.error("Error mapping model to view", e);
        }
        return null;
    }

Add this Bean to your Main Application

@Bean
    AuditorAware<String> auditorProvider() {
    // override getCurrentAuditor method to provide the current user
    return () -> Optional.of(SecurityContextHolder.getContext().getAuthentication().getName());
        }

Add below annotation to your Application Class.

@EnableJpaAuditing(auditorAwareRef = "auditorAware")

Define the bean:

@Bean
public AuditorAware<String> auditorAware(){
    return new CustomAuditAware();
}

Create CustomAuditAware class:

public class CustomAuditAware implements AuditorAware<String> {

    @Override
    public String getCurrentAuditor() {
    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

    if (authentication == null || !authentication.isAuthenticated()) {
        return null;
    }

    return ((User) authentication.getPrincipal()).getUsername();
}

You need to create your custom class that implements AuditorAware<?> in order to define which is your current auditor. So let's define by following code:

public class AuditingService implements AuditorAware<String> {

    @Override
    public Optional<String> getCurrentAuditor() {
        return Optional.of("Bhargav");
    }
}
