I am using Hibernate 4.3.4 with Envers, and MySql 5.6.
Without a JPA 2.1 converter, the Party
entity below fails at Configuration.buildSessionFactory()
as it should, since Hibernate doesn't know what to do with the Name class:
@Entity
@Audited
public class Party
{
protected Name name;
...
}
The exception is:
org.hibernate.MappingException:
Could not determine type for:
ModuloADM.Party.Name,
at table: Party, for columns: [org.hibernate.mapping.Column(name)]
To fix this, I then add this converter:
@Converter (autoApply=true)
public class NametoStringConverter
implements AttributeConverter<Name, String>
{ ... }
And the exception now changes to:
org.hibernate.MappingException:
Could not determine type for:
BasicType adapter for AttributeConverter<Name,String>,
at table: History_Party, for columns: [org.hibernate.mapping.Column(name)]
This is now failing at the Envers auditing table for the Party
entity. Note that History_Party
is the name of the audit table, as chosen by config.setProperty("org.hibernate.envers.audit_table_prefix", "History_")
.
The complete stacktrace is:
org.hibernate.MappingException:
Could not determine type for:
BasicType adapter for AttributeConverter<Name,String>,
at table: History_Party, for columns: [org.hibernate.mapping.Column(name)]

How do I solve this? Is Envers even compatible with AttributeConverters?
