All Implemented Interfaces:
InitializingBean

Deprecated. as of Spring 3.1, in favor of native EntityManager usage (typically obtained through @PersistenceContext)

@Deprecated
public abstract class JpaDaoSupport
extends DaoSupport

Convenient super class for JPA data access objects. Intended for JpaTemplate usage. Alternatively, JPA-based DAOs can be coded against the plain JPA EntityManagerFactory/EntityManager API.

Requires an EntityManagerFactory or EntityManager to be set, providing a JpaTemplate based on it to subclasses. Can alternatively be initialized directly via a JpaTemplate, to reuse the latter's settings such as the EntityManagerFactory, JpaDialect, flush mode, etc.

This class will create its own JpaTemplate if an EntityManagerFactory or EntityManager reference is passed in. A custom JpaTemplate instance can be used through overriding createJpaTemplate.

Method Detail

setEntityManagerFactory

public final void setEntityManagerFactory(javax.persistence.EntityManagerFactory entityManagerFactory)
Deprecated. 
Set the JPA EntityManagerFactory to be used by this DAO. Will automatically create a JpaTemplate for the given EntityManagerFactory.

See Also:
createJpaTemplate(javax.persistence.EntityManagerFactory), setJpaTemplate(org.springframework.orm.jpa.JpaTemplate)

createJpaTemplate

protected JpaTemplate createJpaTemplate(javax.persistence.EntityManagerFactory entityManagerFactory)
Deprecated. 
Create a JpaTemplate for the given EntityManagerFactory. Only invoked if populating the DAO with a EntityManagerFactory reference!

Can be overridden in subclasses to provide a JpaTemplate instance with different configuration, or a custom JpaTemplate subclass.

Parameters:
entityManagerFactory - the JPA EntityManagerFactory to create a JpaTemplate for
Returns:
the new JpaTemplate instance
See Also:
setEntityManagerFactory(javax.persistence.EntityManagerFactory)

setEntityManager

public final void setEntityManager(javax.persistence.EntityManager entityManager)
Deprecated. 
Set the JPA EntityManager to be used by this DAO. Will automatically create a JpaTemplate for the given EntityManager.

See Also:
createJpaTemplate(javax.persistence.EntityManagerFactory), setJpaTemplate(org.springframework.orm.jpa.JpaTemplate)

createJpaTemplate

protected JpaTemplate createJpaTemplate(javax.persistence.EntityManager entityManager)
Deprecated. 
Create a JpaTemplate for the given EntityManager. Only invoked if populating the DAO with a EntityManager reference!

Can be overridden in subclasses to provide a JpaTemplate instance with different configuration, or a custom JpaTemplate subclass.

Parameters:
entityManager - the JPA EntityManager to create a JpaTemplate for
Returns:
the new JpaTemplate instance
See Also:
setEntityManagerFactory(javax.persistence.EntityManagerFactory)

setJpaTemplate

public final void setJpaTemplate(JpaTemplate jpaTemplate)
Deprecated. 
Set the JpaTemplate for this DAO explicitly, as an alternative to specifying a EntityManagerFactory.

See Also:
setEntityManagerFactory(javax.persistence.EntityManagerFactory)

getJpaTemplate

public final JpaTemplate getJpaTemplate()
Deprecated. 
Return the JpaTemplate for this DAO, pre-initialized with the EntityManagerFactory or set explicitly.


checkDaoConfig

protected final void checkDaoConfig()
Deprecated. 
Description copied from class: DaoSupport
Abstract subclasses must override this to check their configuration.
