      Overrides:
      onBeforeSave in class org.springframework.data.mongodb.core.mapping.event.AbstractMongoEventListener<BaseModel>
      Parameters:
      event - The before save event

    • onBeforeConvert

      public void onBeforeConvert(org.springframework.data.mongodb.core.mapping.event.BeforeConvertEvent<BaseModel> event)
      Handles before convert events.

      This method is called before an entity is converted for MongoDB storage. It ensures that the entity has a unique ID, proper audit fields, and encrypted fields if needed.

      Overrides:
      onBeforeConvert in class org.springframework.data.mongodb.core.mapping.event.AbstractMongoEventListener<BaseModel>
      Parameters:
      event - The before convert event
