    <!-- Setter based dependency injection -->
    <!-- Here car order is the parent class and injecting the car insurance
        bean as property and doing the car insurance bean creation there itself -->
    <bean id="carOrder" class="com.vinod.test.CarOrder">

        <property name="carInsurance">
            <bean id="carInsurance" class="com.vinod.test.CarInsurance">
                <property name="name" value="Progressive" />
                <property name="policyDetails" value="Full cover" />
