Class JpaAccessor

java.lang.Object
  extended by org.springframework.orm.jpa.EntityManagerFactoryAccessor
      extended by org.springframework.orm.jpa.JpaAccessor
All Implemented Interfaces:
Aware, BeanFactoryAware, InitializingBean
Direct Known Subclasses:
JpaInterceptor, JpaTemplate

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

@Deprecated
public abstract class JpaAccessor
extends EntityManagerFactoryAccessor
implements InitializingBean

Base class for JpaTemplate and JpaInterceptor, defining common properties such as EntityManagerFactory and flushing behavior.

Not intended to be used directly. See JpaTemplate and JpaInterceptor.

Constructor Detail

JpaAccessor

public JpaAccessor()
Deprecated. 
Method Detail

setEntityManager

public void setEntityManager(javax.persistence.EntityManager entityManager)
Deprecated. 
Set the JPA EntityManager to use.


getEntityManager

public javax.persistence.EntityManager getEntityManager()
Deprecated. 
Return the JPA EntityManager to use.


setJpaDialect

public void setJpaDialect(JpaDialect jpaDialect)
Deprecated. 
Set the JPA dialect to use for this accessor.

The dialect object can be used to retrieve the underlying JDBC connection, for example.


getJpaDialect

public JpaDialect getJpaDialect()
Deprecated. 
Return the JPA dialect to use for this accessor.

Creates a default one for the specified EntityManagerFactory if none set.


setFlushEager

public void setFlushEager(boolean flushEager)
Deprecated. 
Set if this accessor should flush changes to the database eagerly.

Eager flushing leads to immediate synchronization with the database, even if in a transaction. This causes inconsistencies to show up and throw a respective exception immediately, and JDBC access code that participates in the same transaction will see the changes as the database is already aware of them then. But the drawbacks are:


isFlushEager

public boolean isFlushEager()
Deprecated. 
Return if this accessor should flush changes to the database eagerly.


afterPropertiesSet

public void afterPropertiesSet()
Deprecated. 
Eagerly initialize the JPA dialect, creating a default one for the specified EntityManagerFactory if none set.

Specified by:
afterPropertiesSet in interface InitializingBean

flushIfNecessary

protected void flushIfNecessary(javax.persistence.EntityManager em,
                                boolean existingTransaction)
                         throws javax.persistence.PersistenceException
Deprecated. 
Flush the given JPA entity manager if necessary.

Parameters:
em - the current JPA PersistenceManage
existingTransaction - if executing within an existing transaction
Throws:
javax.persistence.PersistenceException - in case of JPA flushing errors

translateIfNecessary

public java.lang.RuntimeException translateIfNecessary(java.lang.RuntimeException ex)
Deprecated. 
Convert the given runtime exception to an appropriate exception from the org.springframework.dao hierarchy if necessary, or return the exception itself if it is not persistence related

Default implementation delegates to the JpaDialect. May be overridden in subclasses.

Parameters:
ex - runtime exception that occured, which may or may not be JPA-related
Returns:
the corresponding DataAccessException instance if wrapping should occur, otherwise the raw exception
