Specifies the value of the discriminator column for the annotated entity type.The
DiscriminatorValue
annotation can only be specified on a concrete entity class.If the
DiscriminatorValue
annotation is not specified, and a discriminator column is used, a provider-specific function is used to generate a value representing the entity type. If theDiscriminatorType
isSTRING
, the discriminator value default is the entity name.The inheritance strategy and the discriminator column are only specified for the root of an entity class hierarchy or subhierarchy in which a different inheritance strategy is applied. But the discriminator value, if not defaulted, should be specified for each concrete entity class in the hierarchy.
