org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager
Imports
jakarta.persistence.spi.PersistenceUnitInfo
Interface that defines an abstraction for finding and managing JPA PersistenceUnitInfos. Used by org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean in order to obtain a jakarta.persistence.spi.PersistenceUnitInfo for building a concrete jakarta.persistence.EntityManagerFactory.

Obtaining a PersistenceUnitInfo instance is an exclusive process. A PersistenceUnitInfo instance is not available for further calls anymore once it has been obtained.
