io.ebean.DuplicateKeyException

All Implemented Interfaces:

Serializable

public class DuplicateKeyException
extends DataIntegrityException

Thrown when a duplicate is attempted on a unique constraint.

In terms of catching this exception with the view of continuing processing using the same transaction look to use Transaction.rollbackAndContinue().

   try (Transaction txn = database.beginTransaction()) {

     try {
       ...
       database.save(bean);
       database.flush();
     } catch (DuplicateKeyException e) {
       // carry on processing using the transaction
       txn.rollbackAndContinue();
       ...
     }

     txn.commit();
   }
