- org.springframework.orm.hibernate4.HibernateTemplate

All Implemented Interfaces:
InitializingBean, HibernateOperations
```
public class HibernateTemplate
extends Object
implements HibernateOperations, InitializingBean
```
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: Hibernate access code can also be coded in plain Hibernate style. Hence, for newly started projects, consider adopting the standard Hibernate style of coding data access objects instead, based on SessionFactory.getCurrentSession(). This HibernateTemplate primarily exists as a migration helper for Hibernate 3 based data access code, to benefit from bug fixes in Hibernate 4.x.

  - setFilterNames
```
public void setFilterNames(String... filterNames)
```
    Set one or more names of Hibernate filters to be activated for all Sessions that this accessor works with.
    Each of those filters will be enabled at the beginning of each operation and correspondingly disabled at the end of the operation. This will work for newly opened Sessions as well as for existing Sessions (for example, within a transaction).

  - 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.

```
    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 MANUAL.
    See Also:
    checkWriteOperationAllowed(org.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.
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    Description copied from interface: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    Specified by:
    afterPropertiesSet in interface InitializingBean
  - execute
```
public <T> T execute(HibernateCallback<T> 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, 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.
    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, Session
  - executeWithNativeSession
```
public <T> T executeWithNativeSession(HibernateCallback<T> action)
```
    Execute the action specified by the given action object within a native Session.
    This execute variant overrides the template-wide "exposeNativeSession" setting.
    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
  - doExecute
```

                          boolean enforceNativeSession)
                   throws DataAccessException
```
    Execute the action specified by the given action object within a Session.
    Parameters:
    action - callback object that specifies the Hibernate action
    enforceNativeSession - whether to enforce exposure of the native Hibernate Session to callback code
    Returns:
    a result object returned by the action, or null
    Throws:
    DataAccessException - in case of Hibernate errors
  - createSessionProxy
```
protected Session createSessionProxy(Session session)
