Instead of referring to a bean you can define bean element inside the property element to make it inline.

Java Code:
<bean id="outer" class="...">
<!-- Instead of using a reference to target, just use an inner bean -->
<property name="target">
<bean class="org.sample.SimpleImpl">
<property name="name"><value>aad</value></property>
<property name="age"><value>52</value></property>
</bean>
</property>
</bean>
