java.lang.Objectorg.springframework.orm.hibernate3.HibernateAccessor
org.springframework.orm.hibernate3.HibernateTemplate
public class HibernateTemplate
Helper class that simplifies Hibernate data access code. Automatically
converts HibernateExceptions into DataAccessExceptions, following the
org.springframework.dao
exception hierarchy.
The central method is execute
, supporting Hibernate access code
implementing the HibernateCallback
interface. It provides Hibernate Session
handling such that neither the HibernateCallback implementation nor the calling
code needs to explicitly care about retrieving/closing Hibernate Sessions,
or handling Session lifecycle exceptions. For typical single step actions,
there are various convenience methods (find, load, saveOrUpdate, delete).
Can be used within a service implementation via direct instantiation with a SessionFactory reference, or get prepared in an application context and given to services as bean reference. Note: The SessionFactory should always be configured as bean in the application context, in the first case given to the service directly, in the second case to the prepared template.
NOTE: As of Hibernate 3.0.1, transactional Hibernate access code can
also be coded in plain Hibernate style. Hence, for newly started projects,
consider adopting the standard Hibernate3 style of coding data access objects
instead, based on org.hibernate.SessionFactory#getCurrentSession()
.
This class can be considered as direct alternative to working with the raw
Hibernate3 Session API (through SessionFactory.getCurrentSession()
).
The major advantage is its automatic conversion to DataAccessExceptions as well
as its capability to fall back to 'auto-commit' style behavior when used outside
of transactions. Note that HibernateTemplate will perform its own Session
management, not participating in a custom Hibernate CurrentSessionContext
unless you explicitly switch "allowCreate"
to "false".
LocalSessionFactoryBean
is the preferred way of obtaining a reference
to a specific Hibernate SessionFactory, at least in a non-EJB environment.
The Spring application context will manage its lifecycle, initializing and
shutting down the factory as part of the application.
Note that operations that return an Iterator (i.e. iterate
)
are supposed to be used within Spring-driven or JTA-driven transactions
(with HibernateTransactionManager, JtaTransactionManager, or EJB CMT).
Else, the Iterator won't be able to read results from its ResultSet anymore,
as the underlying Hibernate Session will already have been closed.
Lazy loading will also just work with an open Hibernate Session,
either within a transaction or within OpenSessionInViewFilter/Interceptor.
Furthermore, some operations just make sense within transactions,
for example: contains
, evict
, lock
,
flush
, clear
.

- if a non-transactional Session should be created when no
transactional Session can be found for the current threadMethod Detail |
---|
public void setAllowCreate(boolean allowCreate)
Session
should be created when no transactional
Session
can be found for the current thread.
The default value is true
.
HibernateTemplate
is aware of a corresponding
Session
bound to the current thread, for example when using
HibernateTransactionManager
. If allowCreate
is
true
, a new non-transactional Session
will be
created if none is found, which needs to be closed at the end of the operation.
If false
, an IllegalStateException
will get thrown in
this case.
NOTE: As of Spring 2.5, switching allowCreate
to false
will delegate to Hibernate's
org.hibernate.SessionFactory#getCurrentSession()
method,
which - with Spring-based setup - will by default delegate to Spring's
SessionFactoryUtils.getSession(sessionFactory, false)
.
This mode also allows for custom Hibernate CurrentSessionContext strategies
to be plugged in, whereas allowCreate
set to true
will always use a Spring-managed Hibernate Session.
SessionFactoryUtils.getSession(SessionFactory, boolean)
public boolean isAllowCreate()
public void setAlwaysUseNewSession(boolean alwaysUseNewSession)
Within a transaction, a new Hibernate Session used by this template will participate in the transaction through using the same JDBC Connection. In such a scenario, multiple Sessions will participate in the same database transaction.
Turn this on for operations that are supposed to always execute independently, without side effects caused by a shared Hibernate Session.

Application exceptions thrown by the action object get propagated to the caller (can only be unchecked). Hibernate exceptions are transformed into appropriate DAO ones. Allows for returning a result object, that is a domain object or a collection of domain objects.
Note: Callback code is not supposed to handle transactions itself!
Use an appropriate transaction manager like
HibernateTransactionManager
. Generally, callback code must not
touch any Session
lifecycle methods, like close,
disconnect, or reconnect, to let the template do its work.
