How to integrate Spring and Hibernate using HibernateDaoSupport

What are the ways to access Hibernate using Spring

There are two approaches to spring’s Hibernate integration:

1.      Inversion of Control with a HibernateTemplate and Callback

2.      Extending HibernateDaoSupport and Applying an AOP Interceptor

How to integrate Spring and Hibernate using HibernateDaoSupport case 2

Spring and Hibernate can integrate using Spring’s SessionFactory called LocalSessionFactory. The integration process is of 3 steps.

• Configure the Hibernate SessionFactory
• Extend your DAO Implementation from HibernateDaoSupport
• Wire in Transaction Support with AOP

1. mapping with the table in the .hbm.xml file

2. <bean id="dataSource"

          class="org.springframework.jdbc.datasource.DriverManagerDataSource">

              <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

              <property name="url" value="jdbc:mysql://localhost:3306/ims"/>

              <property name="username" value="root"/>

              <property name="password" value="root"/>                  

     </bean>

    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" >

    <property name="dataSource" ref="dataSource"/>

    <property name="mappingResources">

        <list>

                               <value>/po/users.hbm.xml</value>

            <value>/po/messages.hbm.xml</value>

            <value>/po/keywords.hbm.xml</value>

            <value>/po/pastsessioninfo.hbm.xml</value>

                  </list>

             </property>

            <property name="hibernateProperties" value="hibernate.dialect=org.hibernate.dialect.MySQLDialect"/>

     </bean>

3. the dao class should implement HibernateDaoSupport
