All Implemented Interfaces:

public class HibernateTemplate
extends HibernateAccessor
implements HibernateOperations

Helper class that simplifies Hibernate data access code, and converts checked HibernateExceptions into unchecked DataAccessExceptions, following the org.springframework.dao exception hierarchy. Uses the same SQLExceptionTranslator mechanism as JdbcTemplate.

Typically used to implement data access or business logic services that use Hibernate within their implementation but are Hibernate-agnostic in their interface. The latter or code calling the latter only have to deal with domain objects, query objects, and org.springframework.dao exceptions.

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.

This class can be considered as direct alternative to working with the raw Hibernate Session API (through SessionFactoryUtils.getSession()). The major advantage is its automatic conversion to DataAccessExceptions, the major disadvantage that no checked application exceptions can get thrown from within data access code. Corresponding checks and the actual throwing of such exceptions can often be deferred to after callback execution, though.

Note that even if HibernateTransactionManager is used for transaction demarcation in higher-level services, all those services above the data access layer don't need to be Hibernate-aware. Setting such a special PlatformTransactionManager is a configuration issue: For example, switching to JTA is just a matter of Spring configuration (use JtaTransactionManager instead) that does not affect application code.

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.

Note: Spring's Hibernate support in this package requires Hibernate 2.1. Dedicated Hibernate3 support can be found in a separate package: org.springframework.orm.hibernate3.

Constructor Detail

HibernateTemplate

public HibernateTemplate()

Create a new HibernateTemplate instance.

HibernateTemplate

public HibernateTemplate(net.sf.hibernate.SessionFactory sessionFactory)

Create a new HibernateTemplate instance.

Parameters:

sessionFactory - SessionFactory to create Sessions

HibernateTemplate

public HibernateTemplate(net.sf.hibernate.SessionFactory sessionFactory,
                         boolean allowCreate)

Create a new HibernateTemplate instance.

Parameters:

sessionFactory - SessionFactory to create Sessions

allowCreate - if a non-transactional Session should be created when no transactional Session can be found for the current thread

Method Detail

setAllowCreate

public void setAllowCreate(boolean allowCreate)

Set if a new Session should be created when no transactional Session can be found for the current thread.

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 found, which needs to be closed at the end of the operation. If false, an IllegalStateException will get thrown in this case.

See Also:

SessionFactoryUtils.getSession(SessionFactory, boolean)

isAllowCreate

public boolean isAllowCreate()

Return if a new Session should be created if no thread-bound found.

setAlwaysUseNewSession

public void setAlwaysUseNewSession(boolean alwaysUseNewSession)

Set whether to always use a new Hibernate Session for this template. Default is "false"; if activated, all operations on this template will work on a new Hibernate Session even in case of a pre-bound Session (for example, within a transaction or OpenSessionInViewFilter).

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.

isAlwaysUseNewSession

public boolean isAlwaysUseNewSession()

Return whether to always use a new Hibernate Session for this template.

setExposeNativeSession

public void setExposeNativeSession(boolean exposeNativeSession)

Set whether to expose the native Hibernate Session to HibernateCallback code. Default is "false": a Session proxy will be returned, suppressing close calls and automatically applying query cache settings and transaction timeouts.

See Also:

HibernateCallback, Session, setCacheQueries(boolean), setQueryCacheRegion(java.lang.String), prepareQuery(net.sf.hibernate.Query), prepareCriteria(net.sf.hibernate.Criteria)

isExposeNativeSession

public boolean isExposeNativeSession()

Return whether to expose the native Hibernate Session to HibernateCallback code, or rather a Session proxy.

setCheckWriteOperations

public void setCheckWriteOperations(boolean checkWriteOperations)

Set whether to check that the Hibernate Session is not in read-only mode in case of write operations (save/update/delete).

Default is "true", for fail-fast behavior when attempting write operations within a read-only transaction. Turn this off to allow save/update/delete on a Session with flush mode NEVER.

See Also:

HibernateAccessor.setFlushMode(int), checkWriteOperationAllowed(net.sf.hibernate.Session), TransactionDefinition.isReadOnly()

isCheckWriteOperations

public boolean isCheckWriteOperations()

Return whether to check that the Hibernate Session is not in read-only mode in case of write operations (save/update/delete).

setCacheQueries

public void setCacheQueries(boolean cacheQueries)

Set whether to cache all queries executed by this template. If this is true, all Query and Criteria objects created by this template will be marked as cacheable (including all queries through find methods).

To specify the query region to be used for queries cached by this template, set the "queryCacheRegion" property.

See Also:

setQueryCacheRegion(java.lang.String), Query.setCacheable(boolean), Criteria.setCacheable(boolean)

isCacheQueries

public boolean isCacheQueries()

Return whether to cache all queries executed by this template.

setQueryCacheRegion

public void setQueryCacheRegion(String queryCacheRegion)

Set the name of the cache region for queries executed by this template. If this is specified, it will be applied to all Query and Criteria objects created by this template (including all queries through find methods).

The cache region will not take effect unless queries created by this template are configured to be cached via the "cacheQueries" property.

See Also:

setCacheQueries(boolean), Query.setCacheRegion(java.lang.String), Criteria.setCacheRegion(java.lang.String)

getQueryCacheRegion

public String getQueryCacheRegion()

Return the name of the cache region for queries executed by this template.

setFetchSize

public void setFetchSize(int fetchSize)

Set the fetch size for this HibernateTemplate. This is important for processing large result sets: Setting this higher than the default value will increase processing speed at the cost of memory consumption; setting this lower can avoid transferring row data that will never be read by the application.

Default is 0, indicating to use the JDBC driver's default.

getFetchSize

public int getFetchSize()

Return the fetch size specified for this HibernateTemplate.

setMaxResults

public void setMaxResults(int maxResults)

Set the maximum number of rows for this HibernateTemplate. This is important for processing subsets of large result sets, avoiding to read and hold the entire result set in the database or in the JDBC driver if we're never interested in the entire result in the first place (for example, when performing searches that might return a large number of matches).

Default is 0, indicating to use the JDBC driver's default.

getMaxResults

public int getMaxResults()

Return the maximum number of rows specified for this HibernateTemplate.

execute

public Object execute(HibernateCallback action)
               throws DataAccessException

Description copied from interface: HibernateOperations

Execute the action specified by the given action object within a 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, i.e. 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.

Specified by:

execute in interface HibernateOperations

Parameters:

action - callback object that specifies the Hibernate action

Returns:

a result object returned by the action, or null

Throws:

DataAccessException - in case of Hibernate errors

See Also:

HibernateTransactionManager, org.springframework.dao, org.springframework.transaction, Session

executeFind

public List executeFind(HibernateCallback action)
                 throws DataAccessException

Description copied from interface: HibernateOperations

Execute the specified action assuming that the result object is a List. This is a convenience method for executing Hibernate find calls or queries within an action.

Specified by:

executeFind in interface HibernateOperations

Parameters:

action - calback object that specifies the Hibernate action

Returns:

a List result returned by the action, or null

Throws:

DataAccessException - in case of Hibernate errors

execute

public Object execute(HibernateCallback action,
                      boolean exposeNativeSession)
               throws DataAccessException

Execute the action specified by the given action object within a Session.

Parameters:

action - callback object that specifies the Hibernate action

exposeNativeSession - whether to expose the native Hibernate Session to callback code

Returns:

a result object returned by the action, or null

Throws:

DataAccessException - in case of Hibernate errors

getSession

protected net.sf.hibernate.Session getSession()

Return a Session for use by this template.

Returns a new Session in case of "alwaysUseNewSession" (using the same JDBC Connection as a transactional Session, if applicable), a pre-bound Session in case of "allowCreate" turned off, and a pre-bound or new Session else (new only if no transactional or otherwise pre-bound Session exists).

See Also:

SessionFactoryUtils.getSession(net.sf.hibernate.SessionFactory, boolean), SessionFactoryUtils.getNewSession(net.sf.hibernate.SessionFactory), setAlwaysUseNewSession(boolean), setAllowCreate(boolean)
