|`@Id`-Property inspection (the default)
|
||||
|By default, Spring Data inspects the version property of the given entity.
|
||||
If the identifier property is `null` or `0` in case of primitive types, then the entity is assumed to be new.
|
||||
Otherwise, it is assumed to not be new.

|Version-Property inspection
|

|`@Version`-Property inspection
|
||||
|If a property annotated with `@Version` is present and `null`, or in case of a version property of primitive type `0` the entity is considered new.
|
||||
If the version property is present but has a different value, the entity is considered to not be new.
|
||||
If no version property is present Spring Data falls back to inspection of the Id-Property.

_Note: Properties of `Persistable` will get detected and persisted if you use `AccessType.PROPERTY`.

To avoid that, use `@Transient`._

|Implementing `EntityInformation`
|
||||
|Providing a custom `EntityInformation` implementation
|
||||
|You can customize the `EntityInformation` abstraction used in the repository base implementation by creating a subclass of the module specific repository factory and overriding the `getEntityInformation(…)` method.
|
||||
You then have to register the custom implementation of module specific repository factory as a Spring bean.
|
||||
Note that this should rarely be necessary.
