    Conditional auditing questions...

    jdot Newbie

      I have the following Entities set up & linked together.


      @Entity

      @Audited

      public class ProductOrder extends Entity  {


           @ManyToOne

           private User user;


      ....


      @Entity

      @Audited

           public class Address extends Entity  {


           @ManyToOne

           private User user;


      ....


      @Entity

      @Audited

      public class User extends Entity


           @OneToMany(mappedBy="user")

           private List<Address> addresses = new ArrayList<Address>();


           private boolean enabled = false;


      ....


      I have then configured custom EventListeners as described in the hibernate doc to perform conditional auditing - I only want to audit an User if it is enabled.

       

      protected static boolean shouldAudit(PostInsertEvent event) {


          boolean audit = true;

          Object entity = event.getEntity();

          if (entity instanceof User) {

                User user = (User) entity;

                audit = user.isEnable();

          }

          else if (entity instanceof java.util.HashMap) {

                System.out.println("why is the entity a HashMap?");

          }

          if (audit) {

                System.out.println("Audit: " + entity.getClass().getSimpleName());

          }

          return audit;

      }


      1) From the logging I noticed that occasionally the "entity" associated to the event is an instance of a HashMap. 

      This only seems to happen when the event.getPersister().getEntityName() is some sort of _AUD entity.

      It seems odd that the "entity" is a HashMap. Is this the correct behaviour?

       


      2) In my test case I created three Users - none of the Users are enabled, then I create a single ProductOrder associated to a given User.

      I was expecting to get no rows in the USER_AUD table, but this is not the case.

      It appears the @ManyToOne user field on Address is causing a USER_AUD row to be inserted.

      If I mark this field as @NotAudited then there is still a row in the USER_AUD table... from the @ManyToOne user field on ProductOrder. Only if I mark both user fields as @NotAudited do I get no User auditing.

      It seems only the "outermost" entity is checked by the conditional auditing and contained references bypass any conditional checks. Is this correct behaviour?

       

      thanks in advance
