3.10.4. Entity Log
This mechanism tracks entity persistence at the entity listeners level, i.e. it is guaranteed to track all changes passing through persistent context of the EntityManager. Direct changes to entities in the database using SQL, including the ones performed using NativeQuery or QueryRunner, are not tracked.
Modified entity instances are passed to
registerDelete() methods of the
EntityLogAPI bean before they are saved to the database. Each method has
auto parameter, allowing separation of automatic logs added by entity listeners from manual logs added by calling these methods from the application code. When these methods are called from entity listeners the value of
auto parameter is
The logs contain information about the time of modification, the user who has modified the entity, and the new values of the changed attributes. Log entries are stored in the SEC_ENTITY_LOG table corresponding to the
EntityLogItem entity. Changed attribute values are stored in the CHANGES column and are converted to instances of
EntityLogAttr entity when they are loaded by the Middleware.
