在Spring 4和Hibernate 4中，SessionFactory为null

Question

When I try to save data to DB the SessionFactory is null . Find the code below.

Spring configuration

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"

</bean>

<!-- DataSource -->

    id="dataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
    <property name="url" value="jdbc:mysql://localhost:3306/hrms"></property>
    <property name="username" value="root"></property>
    <property name="password" value="root"></property>
</bean>

<!-- Hibernate SessionFactory -->
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="hibernateProperties">

            <prop key="hibernate.hbm2ddl.auto">update</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
    <property name="packagesToScan" value="com.service.jaxws"></property>
</bean>

<!-- Transaction -->
<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:annotation-driven transaction-manager="transactionManager" />

Repository Bean

@Repository
public class UserDAOImpl implements UserDAO {

  @Autowired
  private SessionFactory sessionFactory;

  @Override
  public void addUser(UserBO user) {        
    if (sessionFactory != null) {
        sessionFactory.getCurrentSession().save(user);
    } else {
        System.out.println("Null");
    }       
  }
}

When debugging each and every time the SessionFactory is null . Could anyone please tell me what I am missing?

Thanks in advance Serin

Matt the issue has been resolved. The main problem was with the @Autowired. it was not working as expected. I tried this in my @Webservice class. After using the extends SpringBeanAutowiringSupport it is working properly. Anyway thanks for your support.
