<property name="defaultViews">
<list>
<bean
class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
<bean class="org.springframework.web.servlet.view.xml.MarshallingView">
<constructor-arg>
<bean class="org.springframework.oxm.xstream.XStreamMarshaller">
<property name="annotatedClasses">
<array>
<value>com.example.myapp.model.Person</value>
</array>
</property></bean>
</constructor-arg>
</bean>
</list>
</property>
