Custom EntityNotFoundDelegate
- by Felix
Hi all,
I get a org.hibernate.ObjectNotFoundException when I want to delete an object which doesn't exist anymore via hibernate. I just want this exception to be ignored. I could catch the exception and ignore, this would be a solution maybe. But, since there is a hibernate support for ignoring this exception through org.hibernate.cfg.Configuration#entityNotFoundDelegate, I would like to use its advantage and control it using configuration. The question is then, how can I introduce my own/custom implementation of EntityNotFoundDelegate to the org.hibernate.cfg.Configuration? Does anybody have a sample code for me? Just an additional tip, I use Spring Framework as well in my project.
Here is the exception that I get:
Caused by: org.springframework.orm.hibernate3.HibernateObjectRetrievalFailureException: No row with the given identifier exists: [de.mycompany.domain.ResultObject#810b1334-32d3-02b0-e044-769e0ab48e48]; nested exception is org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [de.mycompany.domain.ResultObject#810b1334-32d3-02b0-e044-769e0ab48e48]

And my versions:
Hibernate: 3.3.1
Spring: 2.5.6
Thanks in advance!
