1.5.4. Getting Started with Entity Auditing

Procedure 1.1. Add Auditing Support to a JPA Entity

1. Configure the available auditing parameters to suit the deployment (refer to Section 1.5.5.1, “Configure Envers Parameters”)
2. Open the JPA entity to be audited.
3. Import the org.hibernate.envers.Audited interface.
4. Apply the @Audited annotation to each field or property to be audited, or apply it once to the whole class.

   Example 1.1. Audit Two Fields

   import org.hibernate.envers.Audited;
   
   import javax.persistence.Entity;
   import javax.persistence.Id;
   import javax.persistence.GeneratedValue;
   import javax.persistence.Column;
   
   @Entity
   public class Person {
       @Id
       @GeneratedValue
       private int id;
   
       @Audited
       private String name;
   
       private String surname;
   
       @ManyToOne
       @Audited
       private Address address;
   
       // add getters, setters, constructors, equals and hashCode here
   }

   Example 1.2. Audit an entire Class

   import org.hibernate.envers.Audited;
   
   import javax.persistence.Entity;
   import javax.persistence.Id;
   import javax.persistence.GeneratedValue;
   import javax.persistence.Column;
   
   @Entity
   @Audited
   public class Person {
       @Id
       @GeneratedValue
       private int id;
   
       private String name;
   
       private String surname;
   
       @ManyToOne
       private Address address;
   
       // add getters, setters, constructors, equals and hashCode here
   }
