Listing C-17 Declaring the OpenSessionInViewInterceptor for Use in the Spring View
<bean name="openSessionInViewInterceptor"
class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
<property name="sessionFactory" ref="sessionFactory"/>
<property name="singleSession" value="true"/>
</bean>
The interceptor needs to control the behavior of the session factory, so we must provide it
with a reference to the appropriate bean. We can also dictate whether a single Session object
will be used for the entire duration of the user request. Setting this to true is the most efficient
approach, and therefore the default; however, it has potential side effects, particularly if
declarative transactions are not in use. When set to false , individual sessions will be acquired
for each DAO operation.
The Sample Configuration File
Listing C-18 shows the full Spring configuration file of our example application as a handy ref-
erence to what's required in creating a Hibernate-based Spring application.
