Class EntityExistsException

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

jakarta.persistence.PersistenceException

jakarta.persistence.EntityExistsException

All Implemented Interfaces:

Serializable

public class EntityExistsException
extends PersistenceException

Thrown by the persistence provider when:

• a detached instance of an entity type is passed to EntityManager.persist(Object), or
• any kind of uniqueness constraint is violated when an entity is inserted in the database.

The persistence provider is always permitted to postpone an EntityExistsException until execution of the resulting database insert operation. If a detached instance is passed to the persist operation, either:

• an EntityExistsException is immediately thrown by persist(), or
• an EntityExistsException or some other subtype of PersistenceException is thrown when the persistence context is flushed or when the transaction commits.

If an EntityExistsException is thrown by an EntityManager with a persistence context joined to an active transaction, the transaction is automatically marked for rollback when the exception is thrown.

1.0
