Spring mvc configuration JSON

[gcarl]

I would know how works the configuration about Spring MVC rest services that returns JSON.

I have configurated the applicationContenxt.xml in this way:

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
        </list>
    </property>
</bean>
<bean id="contentNegotiatingViewResolver" class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json"/>
        </map>
    </property>
    <property name="defaultViews">
        <list>
            <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"/>
        </list>
    </property>
</bean>
<bean class="com.MyController"></bean>

And this is the code of my controller:

@Controller(value="MyController")
public class MyController {
@RequestMapping(value="/getValue", method=RequestMethod.GET)
    public ModelAndView getValue() {
    Map model = new HashMap();
    model.put("asasa", "bbbbb");
    model.put("cccc", "ddddd");
      return new ModelAndView("jsonView",model);
 }
}

I'm missing something about xml configuration or Java code? I have always error 404 while trying to invoke this resource: http://localhost:8080/fss/MyController/getValue

Try to start debug your code from DispatcherServlet#doDispatch. Review all HandlerMapping(s), View Resolvers, etc DispatcherServlet operates with.

Usually all such simple issues are simply can be resolved by debugging.
