<context:annotation-config> declares support for general annotations such as @Required, @Autowired, @PostConstruct,
and so on.
<mvc:annotation-driven /> is actually rather pointless. It declares explicit support for annotation-driven MVC controllers (i.e.@RequestMapping, @Controller,
etc), even though support for those is the default behaviour.
My advice is to always declare <context:annotation-config>, but don't bother with <mvc:annotation-driven /> unless you want JSON support via Jackson.
