Spring represents the configured session factory as a LocalSessionFactoryBean . Our exam-
ple application uses annotations to manage the mappings, so we specify that the Hibernate
AnnotationConfiguration type should be used in our bean instead of the default Configuration .
n Caution Spring maintains two sets of Hibernate packages: org.springframework.orm.hibernate...
for Hibernate 2 functionality, and org.springframework.orm.hibernate3... for Hibernate 3 functional-
ity—a single-character difference. Be careful to select the correct one, as debugging the ClassNotFound
and similar exceptions that result if you use the wrong one can be extremely time-consuming!
We also specify the location and name of the configuration file relative to the classpath as
indicated by the classpath: prefix (see Listing C-3).
Listing C-3. Configuring a Session Factory Bean in Spring
<bean id="sessionFactory"
class=" org.springframework.orm.hibernate3.LocalSessionFactoryBean ">
<property name="configurationClass"
value=" org.hibernate.cfg.AnnotationConfiguration " />
<property name="configLocation"
value=" classpath:hibernate.cfg.xml " />
</bean>
As noted, our simple web application derives its database connection details from the
Hibernate configuration file. However, a larger web application typically needs to provide
database resources to other applications, in which case a Hibernate-specific configuration file
