How to enable #JsonRootName in spring mvc 3.2 - spring-mvc

Question

I'm using Spring 3.2 and my Spring MVC controller generate JSON data (with jackson-databind-2.2.0). I would like to customize my JSON root name with #JsonRootName (com.fasterxml.jackson.annotation.JsonRootName) annotation, however, I could not figure out how to enable it with Spring configuration.
#JsonRootName("rootNameTest")
public class MyModel {
private String prop;
public String getProp() {
return prop;
}
public void setProp(String prop) {
this.prop = prop;
}
}
Here's my settings in sevlet-context.xml
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="order" value="1" />
<property name="contentNegotiationManager">
<bean class="org.springframework.web.accept.ContentNegotiationManager">
<constructor-arg>
<bean class="org.springframework.web.accept.ParameterContentNegotiationStrategy">
<constructor-arg>
<map>
<entry key="json" value="application/json"/>
</map>
</constructor-arg>
</bean>
</constructor-arg>
</bean>
</property>
<property name="defaultViews">
<list>
<bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>
</list>
</property>
</bean>
Please help. Thanks.

Setbelow in com.fasterxml.jackson.databind.ObjectMapper
om.configure(DeserializationFeature.UNWRAP_ROOT_VALUE, true);
om.configure(SerializationFeature.WRAP_ROOT_VALUE, true);
this may be done by extending above Class with your custom and inject in org.springframework.http.converter.json.MappingJackson2HttpMessageConverter
