Class HibernateInterceptor

java.lang.Object

org.springframework.orm.hibernate3.HibernateAccessor

org.springframework.orm.hibernate3.HibernateInterceptor

All Implemented Interfaces:

Advice, Interceptor, MethodInterceptor, Aware, BeanFactoryAware, InitializingBean

Deprecated.

as of Spring 3.2.7, in favor of either HibernateTemplate usage or native Hibernate API usage within transactions, in combination with a general PersistenceExceptionTranslationPostProcessor. Note: This class does not have an equivalent replacement in orm.hibernate4. If you desperately need a scoped Session bound through AOP, consider the newly introduced OpenSessionInterceptor.

@Deprecated
public class HibernateInterceptor
extends HibernateAccessor
implements MethodInterceptor

This interceptor binds a new Hibernate Session to the thread before a method call, closing and removing it afterwards in case of any method outcome. If there already is a pre-bound Session (e.g. from HibernateTransactionManager, or from a surrounding Hibernate-intercepted method), the interceptor simply participates in it.

Application code must retrieve a Hibernate Session via the SessionFactoryUtils.getSession method or - preferably - Hibernate's own SessionFactory.getCurrentSession() method, to be able to detect a thread-bound Session. Typically, the code will look like as follows:

 public void doSomeDataAccessAction() {
   Session session = this.sessionFactory.getCurrentSession();
   ...
   // No need to close the Session or translate exceptions!
 }

Note that this interceptor automatically translates HibernateExceptions, via delegating to the SessionFactoryUtils.convertHibernateAccessException method that converts them to exceptions that are compatible with the org.springframework.dao exception hierarchy (like HibernateTemplate does). This can be turned off if the raw exceptions are preferred.

This class can be considered a declarative alternative to HibernateTemplate's callback approach. The advantages are:

• no anonymous classes necessary for callback implementations;
• the possibility to throw any application exceptions from within data access code.

The drawback is the dependency on interceptor configuration. However, note that this interceptor is usually not necessary in scenarios where the data access code always executes within transactions. A transaction will always have a thread-bound Session in the first place, so adding this interceptor to the configuration just adds value when fine-tuning Session settings like the flush mode - or when relying on exception translation.

Method Detail

setExceptionConversionEnabled

public void setExceptionConversionEnabled(boolean exceptionConversionEnabled)

Deprecated.

Set whether to convert any HibernateException raised to a Spring DataAccessException, compatible with the org.springframework.dao exception hierarchy.

Default is "true". Turn this flag off to let the caller receive raw exceptions as-is, without any wrapping.

invoke

public Object invoke(MethodInvocation methodInvocation)
              throws Throwable

Deprecated.

Description copied from interface: MethodInterceptor

Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().

Specified by:

invoke in interface MethodInterceptor

Parameters:

methodInvocation - the method invocation joinpoint

Returns:

the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor

Throws:

Throwable - if the interceptors or the target object throws an exception

getSession

protected Session getSession()

Deprecated.

Return a Session for use by this interceptor.
