Spring Config for Hibernate Session

Question

Hi I'm trying to obtain hibernate's Session through Spring's injection.

Here's my spring context xml:

  <!-- hibernate's session factory -->
  <bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="configLocation">
      <value>classpath:./hibernate.cfg.xml</value>
    </property>
  </bean>

  <!-- the transaction manager -->
  <bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
  </bean>

Here's the code:

private static ApplicationContext ctx;

    if (ctx == null) {
        ctx = new ClassPathXmlApplicationContext("springContext.xml");
    }
    LocalSessionFactoryBean sf = ctx.getBean(LocalSessionFactoryBean.class);
    session = sf.getObject().getCurrentSession();

However the session I obtain is null.

Is it correct to get Session through sf.getObject().getCurrentSession() ?

Thanks :)

I don't think you should access the session like that. Either use HibernateTemplate or inject SessionFactory in your beans and call getCurrentSession() on it. Otherwise your transaction management won't be handled properly
