We have entities with Instant fields which are mapped to DATE columns in our Oracle DB. As of Hibernate 6 the default mapping for Instant is to TIMESTAMP WITH TIME ZONE columns, but this default can be overridden by setting hibernate.type.preferred_instant_jdbc_type=TIMESTAMP. However it appears that envers doesn’t recognise this option, and adding a @JdbcType or @JdbcTypeCode annotation explicitly on the entity fields doesn’t work either. This results in errors like this when inserting audit records: Caused by: org.hibernate.exception.GenericJDBCException: could not insert: [uk.co.mycompany.MyEntity_AUD] at org.hibernate.exception.internal.StandardSQLExceptionConverter.convert(StandardSQLExceptionConverter.java:61) at org.hibernate.engine.jdbc.spi.SqlExceptionHelper.convert(SqlExceptionHelper.java:109) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:3447) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:4058) at org.hibernate.action.internal.EntityInsertAction.execute(EntityInsertAction.java:103) at org.hibernate.engine.spi.ActionQueue.executeActions(ActionQueue.java:612) at org.hibernate.engine.spi.ActionQueue.lambda$executeActions$1(ActionQueue.java:483) at java.base/java.util.LinkedHashMap.forEach(LinkedHashMap.java:721) at org.hibernate.engine.spi.ActionQueue.executeActions(ActionQueue.java:480) at org.hibernate.event.internal.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:329) at org.hibernate.event.internal.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:39) at org.hibernate.event.service.internal.EventListenerGroupImpl.fireEventOnEachListener(EventListenerGroupImpl.java:107) at org.hibernate.internal.SessionImpl.doFlush(SessionImpl.java:1425) ... 194 common frames omitted Caused by: java.sql.SQLException: Invalid column type: 2014 at oracle.jdbc.driver.OracleStatement.getInternalType(OracleStatement.java:4369) at oracle.jdbc.driver.OraclePreparedStatement.setNullCritical(OraclePreparedStatement.java:5836) at oracle.jdbc.driver.OraclePreparedStatement.setNull(OraclePreparedStatement.java:5818) at oracle.jdbc.driver.OraclePreparedStatementWrapper.setNull(OraclePreparedStatementWrapper.java:1292) at com.zaxxer.hikari.pool.HikariProxyPreparedStatement.setNull(HikariProxyPreparedStatement.java) at org.hibernate.type.descriptor.jdbc.BasicBinder.doBindNull(BasicBinder.java:100) at org.hibernate.type.descriptor.jdbc.BasicBinder.bind(BasicBinder.java:53) at org.hibernate.type.AbstractStandardBasicType.nullSafeSet(AbstractStandardBasicType.java:221) at org.hibernate.type.AbstractStandardBasicType.nullSafeSet(AbstractStandardBasicType.java:217) at org.hibernate.type.AbstractSingleColumnStandardBasicType.nullSafeSet(AbstractSingleColumnStandardBasicType.java:34) at org.hibernate.persister.entity.AbstractEntityPersister.dehydrate(AbstractEntityPersister.java:3237) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:3420) ... 204 common frames omitted For me there’s a simple workaround of creating an AttributeConverter to explicitly define the mapping behaviour I want, which envers does pick up and apply to its generated entity definitions (you can see this in the envers HBM dump where the field type is marked as converted:: ). But I’d expect all of the type mapping logic which applies to the entity class to be applied to the audit entity in a consistent way.
