How to set visibility for default ObjectMapper used by MappingJackson2JsonView, using Spring ContentNegotiatingViewResolver

Question

I'd like to do what's suggested here, namely:

objectMapper.setVisibility(JsonMethod.FIELD, Visibility.ANY);

Unfortunately the Json mapping for my app is done entirely in xml, like this:

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
  <property name="contentNegotiationManager" ref="contentNegotiationManager"/>
  <property name="defaultViews">
    <list>
      <bean name="jsonView" class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>
    </list>
  </property>
</bean>

I don't need a custom ObjectMapper, I'd just like to be able to set the visibility of the default ObjectMapper that is used by MappingJackson2JsonView.

Is there any way to do this?

You can't change the default ObjectMapper used by MappingJackson2JsonView. It is stored in a private field and no methods exist to modify the object.

However, you can declare your own ObjectMapper bean and use MappingJackson2JsonView#setObjectMapper(ObjectMapper) to have the View use your custom ObjectMapper bean.
