JQuery, Spring MVC @RequestBody and JSON - making it work together

I would like to have a bidirectional JSON to Java serialization

I'm using successfully the Java to JSON to JQuery path... ( @ResponseBody ) e.g.

@RequestMapping(value={"/fooBar/{id}"}, method=RequestMethod.GET)

     public @ResponseBody FooBar getFooBar(

            @PathVariable String id,

            HttpServletResponse response , ModelMap model) {

        response.setContentType("application/json");

...

}

and In JQuery I use

$.getJSON('fooBar/1', function(data) {

    //do something

});

this works well (e.g. annotations work already, thanks to all the answerers)

However, how do I do the reverse path: have JSON be serialized to a Java Object back using RequestBody?

no matter what I try, I can't get something like this to work:

@RequestMapping(value={"/fooBar/save"}, method=RequestMethod.POST)

public String saveFooBar(@RequestBody FooBar fooBar,

        HttpServletResponse response , ModelMap model) {



  //This method is never called. (it does when I remove the RequestBody...)

}

I have Jackson configured correctly (it serializes on the way out) and I have MVC set as annotations driven of course

How do I make it work? is it possible at all? or is Spring / JSON / JQuery is oneway (out)?

Update:

I changed this Jackson setting

<bean id="jsonHttpMessageConverter"

    class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />



<!-- Bind the return value of the Rest service to the ResponseBody. -->

<bean

    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

    <property name="messageConverters">

        <util:list id="beanList">

            <ref bean="jsonHttpMessageConverter" />

<!--            <ref bean="xmlMessageConverter" /> -->              

        </util:list>

    </property>

</bean>

To the (almost similiar one) suggested

<bean id="jacksonMessageConverter"

    class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean>

    <bean

        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

        <property name="messageConverters">

            <list>

                <ref bean="jacksonMessageConverter" />

            </list>

        </property>

    </bean>

And it seems to work! I don't know what exactly did the trick, but it works...
