# hibernate.properties

<Info>
  When using the Spring Boot Starter, Hibernate properties are provided through an `IWhatIfPersistenceProperties` bean rather than a separate properties file. See [project configuration](../../dev-getting-started/dev-configure-acc/configuration-project) for details.
</Info>

The **hibernate.properties** file details the configurations used when setting up the Hibernate implementation of the simulation persistence manager.

Location: the application **src/main/resources**
