```
public class HibernateTemplate
extends HibernateAccessor
implements HibernateOperations
```
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 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.

    Create a new HibernateTemplate instance.
    
    Parameters:

  - HibernateTemplate
```
public HibernateTemplate(SessionFactory sessionFactory,
                 boolean allowCreate)
```
    Create a new HibernateTemplate instance.
    
    Parameters:
    sessionFactory - the SessionFactory to create Sessions with
    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. 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 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.
    
    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(org.hibernate.Query), prepareCriteria(org.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(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.
  - 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
