How to set a global Validator for Spring VMC (non-XML way)

I've got all everything setup and everything works great using something like below.

@Controller
public class MyController {

    @Autowired
    private Validator validator;

    @InitBinder
    protected void initBinder(WebDataBinder binder) {
       binder.setValidator(validator);
    }

However, I've seen from the documentation that I could define a globalValidator like below:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
    xmlns:mvc="http://ift.tt/1bHqwjR"
    xmlns:xsi="http://ift.tt/ra1lAU"
    xsi:schemaLocation="
        http://ift.tt/GArMu6
        http://ift.tt/1jdM0fG
        http://ift.tt/1bHqwjR
        http://ift.tt/1fmimld">

    <mvc:annotation-driven validator="globalValidator"/>

</beans>

Question: How can I do it using Java configuration and no XML?
