Hibernate Envers in Grails

Question

I would like to use Hibernate Envers in my Grails (v3.0.11) application. Since the grails envers plugins are dead, I tried to do it on my own.

What I did:

in build.gradle, I added the Hibernate Envers dependency compile "org.hibernate:hibernate-envers"

My domain looks like:

import org.hibernate.envers.Audited

@Audited
class Hotel {
    String name
}

in the scaffolded Controller, I only changed:

class HotelController {

    ...

    @Transactional
    def save(Hotel hotel) {
        ...
        Hotel.withTransaction {
            hotel.save flush:true    
        }
        ...
    }

    ...

}

I get the following exception when saving:

URI
    /hotel/save
Class
    org.hibernate.envers.exception.AuditException
Message
    null

What am I doing wrong? How to make the transaction "active" ?

Answer 1

try excluding the transitive dependencies of envers. worked for me. i guess pulling in hibernate-entitymanager does not do any good here. so:

compile("org.hibernate:hibernate-envers") { transitive = false }
