      • isProvider

        public static boolean isProvider​(PersistenceUnitDescriptor persistenceUnit,
                                 Map integration)
        Does the descriptor and/or integration request Hibernate as the PersistenceProvider? Note that in the case of no requested provider being named we assume we are the provider (the calls got to us somehow...)
        参数:
        persistenceUnit - The <persistence-unit/> descriptor.
        integration - The integration values.
        返回:
        true if Hibernate should be the provider; false otherwise.

      • hibernateProviderNamesContain

        public static boolean hibernateProviderNamesContain​(String requestedProviderName)
        Is the requested provider name one of the recognized Hibernate provider names?
        参数:
        requestedProviderName - The requested provider name to check against the recognized Hibernate names.
        返回:
        true if Hibernate should be the provider; false otherwise.

      • extractRequestedProviderName

        public static String extractRequestedProviderName​(PersistenceUnitDescriptor persistenceUnit,
                                                  Map integration)
        Extract the requested persistence provider name using the algorithm Hibernate uses. Namely, a provider named in the 'integration' map (under the key '"javax.persistence.provider"') is preferred, as per-spec, over value specified in persistence unit.
        参数:
        persistenceUnit - The <persistence-unit/> descriptor.
        integration - The integration values.
        返回:
        The extracted provider name, or null if none found.
