You can take full control over the session creation by adding either an `org.neo4j.ogm.config.Configuration` bean or an `org.neo4j.ogm.session.SessionFactory` bean.

The auto-configured `Driver` is created using `ConfigBuilder`.
|

To fine-tune its configuration, declare one or more `ConfigBuilderCustomizer` beans.
|
||||
Each will be called in order with the `ConfigBuilder` that is used to build the `Driver`.
