Copy code
static mapping = {
id generator: 'uuid.hex'
} Copy code
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.grails.orm.hibernate.HibernateDatastore]: Constructor threw exception; nested exception is org.grails.datastore.mapping.model.DatastoreConfigurationException: Invalid id generation strategy for entity [com.k_int.ciim.mgmt.provider.Provider]: uuid.hext

Copy code
String id = UUID.randomUUID().toString()
static mapping = {
id generator: 'assigned'
}m

04/02/2024, 8:06 PMHi Mark, this seems to work:
Copy code
class Book {
String id
Sting name
static mapping = {
id generator: 'org.hibernate.id.UUIDHexGenerator'
}
}mattias_reichel
04/02/2024, 8:12 PMThat actually seems to do the same as:
Copy code
class Book {
String id
Sting name
static mapping = {
id generator: 'uuid'
}

Copy code
import java.util.UUID
class Book {
UUID id
Sting name
static mapping = {
id generator: 'uuid2'
}
}m

04/02/2024, 9:01 PMThanks Mattias, I don't see any mention of uuid2 in https://docs.grails.org/latest/ref/Database%20Mapping/id.html

04/02/2024, 9:25 PMYou are right. I created a PR to fix that.
