creating one session factory from two or more applicationContext files having their own POJO list

[Rahul Babbar]

Hi.

I have two applicationContext files coming from two different sources(jars)...and each of them have their applicationContext, and having declaration of sessionFactory.
But when i read both these applicationContexts i want to create a single instance of SessionFactory.

The problem is in automatic merging of lists of two files.

Here is the portion of applicationContext-A.xml

  <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>value.A</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
            org.hibernate.dialect.OracleDialect
                </prop>
                 <prop key="hibernate.show_sql">
            true
                </prop>
            </props>
        </property>
    </bean>  

ApplicationContext-B.xml

  <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>value.B</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
            org.hibernate.dialect.OracleDialect
                </prop>
                 <prop key="hibernate.show_sql">
            true
                </prop>
            </props>
        </property>
    </bean>  

What is required is

  <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>value.A</value>
                <value>value.B</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
            org.hibernate.dialect.OracleDialect
                </prop>
                 <prop key="hibernate.show_sql">
            true
                </prop>
            </props>
        </property>
    </bean>  

Can anyone explain how to accomplish this?

Thank you

Well the instance of SessionFactory will be stored in a map, under the key "sessionFactory" so if you have more than one bean definition with the same id, but in different files, the last one read in wins. So this means that you can overwrite the other two definitions with yours, as long as you make sure yours is the last xml file read in.
