How to reuse beans using inheritance ?

Spring offers an inheritance-like mechanism to reduce the duplication of configuration information and make the XML configuration simpler.

A child bean definition can inherit configuration information from its parent bean, which essentially serves as a template for the child beans.

You need to specify abstract=true for the parent bean, and the parent reference in the child bean.

Example

<bean id="abstractService" abstract="true“  

      class="com.xyz.AbstractService">

   <property name="companyName" value="xyz1" />

</bean>

<bean id="shippingService" parent="abstractService"

      class="com.xyz.ShippingService">

  <property name="shippedBy" value="xyz2" />

</bean>
