11.7.5.4. Envers Configuration Properties

org.hibernate.envers.audit_table_prefix

A string that is prepended to the name of an audited entity, to create the name of the entity that will hold the audit information.

org.hibernate.envers.audit_table_suffix

_AUD

A string that is appended to the name of an audited entity to create the name of the entity that will hold the audit information. For example, if an entity with a table name of Person is audited, Envers will generate a table called Person_AUD to store the historical data.

org.hibernate.envers.revision_field_name

REV

The name of the field in the audit entity that holds the revision number.

org.hibernate.envers.revision_type_field_name

REVTYPE

The name of the field in the audit entity that holds the type of revision. The current types of revisions possible are: add, mod and del.

org.hibernate.envers.revision_on_collection_change

true

This property determines if a revision should be generated if a relation field that is not owned changes. This can either be a collection in a one-to-many relation, or the field using the mappedBy attribute in a one-to-one relation.

org.hibernate.envers.do_not_audit_optimistic_locking_field

true

When true, properties used for optimistic locking (annotated with @Version) will automatically be excluded from auditing.

org.hibernate.envers.store_data_at_delete

false

This property defines whether or not entity data should be stored in the revision when the entity is deleted, instead of only the ID, with all other properties marked as null. This is not usually necessary, as the data is present in the last-but-one revision. Sometimes, however, it is easier and more efficient to access it in the last revision. However, this means the data the entity contained before deletion is stored twice.

org.hibernate.envers.default_schema

null (same as normal tables)

The default schema name used for audit tables. Can be overridden using the @AuditTable(schema="...") annotation. If not present, the schema will be the same as the schema of the normal tables.

org.hibernate.envers.default_catalog

null (same as normal tables)

The default catalog name that should be used for audit tables. Can be overridden using the @AuditTable(catalog="...") annotation. If not present, the catalog will be the same as the catalog of the normal tables.

org.hibernate.envers.audit_strategy

org.hibernate.envers.strategy.DefaultAuditStrategy

This property defines the audit strategy that should be used when persisting audit data. By default, only the revision where an entity was modified is stored. Alternatively, org.hibernate.envers.strategy.ValidityAuditStrategy stores both the start revision and the end revision. Together, these define when an audit row was valid.

org.hibernate.envers.audit_strategy_validity_end_rev_field_name

REVEND

The column name that will hold the end revision number in audit entities. This property is only valid if the validity audit strategy is used.

org.hibernate.envers.audit_strategy_validity_store_revend_timestamp

false

This property defines whether the timestamp of the end revision, where the data was last valid, should be stored in addition to the end revision itself. This is useful to be able to purge old audit records out of a relational database by using table partitioning. Partitioning requires a column that exists within the table. This property is only evaluated if the ValidityAuditStrategy is used.

org.hibernate.envers.audit_strategy_validity_revend_timestamp_field_name

REVEND_TSTMP

Column name of the timestamp of the end revision at which point the data was still valid. Only used if the ValidityAuditStrategy is used, and org.hibernate.envers.audit_strategy_validity_store_revend_timestamp evaluates to true.
