Question

I work with Spring 3.1 + Hibernate 4.

I’ve created the following sessionFactory:

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="myDataSource" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">validate</prop>
        </props>
    </property>
    <property name="packagesToScan" value="com.my.company"/>
</bean>

As you see, the above sessionFactory is for Hibernate 4.

I am trying to crate a HibernateTemplate (org.springframework.orm.hibernate3.HibernateTemplate) through Java code, by that sessionFactory, but I am not sure how to do this.

I’ve tried the following code:

@Resource(name="sessionFactory")
public void setSessionFactory(LocalSessionFactoryBean sessionFactory) {
    this.hibernateTemplate = new HibernateTemplate(sessionFactory.getObject());
}

But I’m getting the following error message:

org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'sessionFactory' must be of type [org.springframework.orm.hibernate4.LocalSessionFactoryBean], but was actually of type [org.hibernate.internal.SessionFactoryImpl]

Could you show how to do this?

As from this post:

HibernateTemplate isn’t recommended for use anymore (about since the
release of hibernate 3.0.1) there is no more added value so that isn’t
going to be in there anymore for hibernate 4. Simply use the plain
SessionFactory and use the getCurrentSession method to obtain the
current transactional session (don’t use openSession!!!!) and you are
good to go…

From the javadoc of package org.springframework.orm.hibernate4:

Contains an implementation of Spring’s transaction SPI for local
Hibernate transactions. This package is intentionally rather minimal,
with no template classes or the like, in order to follow native
Hibernate recommendations as closely as possible.
