public class HibernateTemplate extends Object implements HibernateOperations, InitializingBean
Helper class that simplifies Hibernate data access code. Automatically converts HibernateExceptions into DataAccessExceptions, following theorg.springframework.dao
exception hierarchy.The central method is
execute
, supporting Hibernate access code implementing theHibernateCallback
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.- 从以下版本开始:

HibernateTemplate
public HibernateTemplate()

方法详细资料
setSessionFactory
public void setSessionFactory(SessionFactory sessionFactory)
Set the Hibernate SessionFactory that should be used to create Hibernate Sessions.
getSessionFactory
public SessionFactory getSessionFactory()
Return the Hibernate SessionFactory that should be used to create Hibernate Sessions.
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).
getFilterNames
public String[] getFilterNames()
Return the names of Hibernate filters to be activated, if any.
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.
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 MANUAL.
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.
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.
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()
从接口复制的说明:InitializingBean

execute
public <T> T execute(HibernateCallback<T> action) throws DataAccessException
从接口复制的说明:HibernateOperations
Execute the action specified by the given action object within aSession
.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.

HibernateTransactionManager
. Generally, callback code must not touch anySession
lifecycle methods, like close, disconnect, or reconnect, to let the template do its work.- 指定者:
