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, to be able to detect a thread-bound Session. It is preferable to use getSession with allowCreate=false, if the code relies on the interceptor to provide proper Session handling. Typically, the code will look like as follows:

 public void doSomeDataAccessAction() {
   Session session = SessionFactoryUtils.getSession(this.sessionFactory, false);
   try {
   catch (HibernateException ex) {
     throw SessionFactoryUtils.convertHibernateAccessException(ex);
Note that the application must care about handling HibernateExceptions itself, preferably 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).

Unfortunately, this interceptor cannot convert checked HibernateExceptions to unchecked dao ones transparently. The intercepted method would have to declare the checked HibernateException - thus the caller would still have to catch or rethrow it, even if it will never be thrown if intercepted. Any such exception will nevertheless get converted by default.

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

The drawbacks are:

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.

Method Detail


public void setExceptionConversionEnabled(boolean exceptionConversionEnabled)
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. Note that this means that the DAO methods will have to declare the checked HibernateException, and callers will be forced to handle it.
