Convert Hibernate exceptions in Spring Roo to Spring Data Access exceptions

Question

I am currently working on a Spring Roo project and I want the exceptions thrown by Hibernate to be converted to Spring Exceptions. Eg I want the Hibernate exception ConstraintViolationException to be converted to Spring's DataIntegrityViolationException.

I have done this in Spring projects previously by adding in the following code to my Spring config:

<!-- Translates Hibernate exceptions to Spring Data Access Exceptions -->
<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>

However in Roo this does not work. Can anybody tell me how I can get this working and why it doesn't work in Roo?

Answer 1

You must setup the persistence layer as JPA Repository in order Roo configures your project to use Spring Data.
