title: How do I obtain the Jackson ObjectMapper in use by Spring 4.1?
body: <p>Spring 4.1 instantiates a Jackson <code>ObjectMapper</code> instance. I have reason to want to <code>@Autowire</code> that instance into one of my controllers: The controller does some minor JSON parsing of its own using Jackson, but the <code>ObjectMapper</code> it uses should be the one and same instance that Spring itself is using. How do I go about accomplishing that?</p>
  
  <p>Note that I'm not asking how to custom configure the <code>ObjectMapper</code> in use by Spring; I'm happy with the defaults. I just want to fish the instance used by Spring out so that I can re-use the existing instance in my own code.</p>
