XML Configuration

<bean id="address" class="springcore.setterwithref.Address">

    <property name="city" value="Hyd"/>
    <property name="pincode" value="457001"/>

</bean>

<bean id="employee" class="springcore.setterwithref.Employee">

    <property name="id" value="101"/>
    <property name="name" value="Prakhar"/>
    <property name="add" ref="address"/>

</bean>

---

Output

Employee{id=101, name='Prakhar', add=Address{city='Hyd', pincode=457001}}
