Simplifying Entity Auditing with Spring Data JPA Annotations

Keeping track of who created and modified your entities is crucial for various purposes, including audit trails, security, and data lineage. Spring Data JPA offers a convenient and efficient way to achieve this through dedicated annotations: @CreatedBy, @LastModifiedBy, @CreatedDate, and @LastModifiedDate.

Leveraging Annotations

Let’s consider a simple Product entity:


public class Product {

    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name;

    private String createdBy;

    private String lastModifiedBy;

    private Date createdDate;

    private Date lastModifiedDate;

    // Getters and Setters
  • @CreatedBy and @LastModifiedBy: These annotations mark fields that will hold the username or identifier of the user who created and last modified the entity, respectively.
  • @CreatedDate and @LastModifiedDate: These annotations mark fields that will automatically store the creation and last modification timestamps. Spring Data JPA automatically injects the current user and timestamp during entity persistence and updates.

Maven and Gradle Dependencies

To utilize these annotations, you need the spring-data-jpa dependency:





implementation 'org.springframework.boot:spring-data-jpa'

Optional: Enabling Auditing

Spring Data JPA auditing is enabled by default, but if explicitly desired, add the following configuration class:


public class AuditingConfig {

How it Works

Behind the scenes, Spring Data JPA utilizes an AuditingEntityListener that intercepts entity lifecycle events like save and update. It retrieves the current user information (typically from the security context) and the current timestamp to populate the annotated fields before persisting the entity.

Additional Notes

  • The annotations support various field types like String, Long, and Date. Consider using specific user identifier types instead of usernames for better data integrity.
  • You can customize the behavior of these annotations by implementing an AuditorAware interface and providing a custom logic to determine the user information.

In conclusion, these annotations provide a straightforward approach to maintain audit trails and user-related information within your Spring Data JPA entities. By leveraging them effectively, you can simplify data management and enhance the traceability of your application.
