Question

I want to insert some data in a table of database after the SessionFactory of spring hibernate has been created.

I have a CUSTOMER table and I want to insert a particular Customer into this table if the Customer doesn’t exist.

This is the configuration of SessionFactory:

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
    <property name="packagesToScan" value="com.edfx.adb.persist.entity" />
    <property name="entityInterceptor" ref="entityInterceptor" />
</bean>

I know that there is an option hibernate.hbm2ddl.import_files from which we can mention a sql file and the query will be executed at the time of SessionFactory initialization. But I don’t want to follow this way.

Also I have found that we can use ServletContextListener for this kind of purpose, but I am not sure this is a good way to achieve what I want. Because what I understand is the listener will be initialized after deployment of war file, when the first user hit the application. So if I have a Scheduler which operates of the Customer and if the Scheduler get executed before any user hit the app, then the Scheduler wouldn’t find that need-to-be-insert data.

Any pointer would be very helpful to me.

You can extend org.springframework.orm.hibernate4.LocalSessionFactoryBean and override buildSessionFactory() method to according to your requirement.
