Spring RequestMapping parameter custom annotation

Question

in my web application I have many places where I need to retrieve current logged account (from session).

Account account = getAccountFromSession(session);

This piece of code is repeated many many times. I wonder if this is possible to make my request look something like this:

@RequestMapping(value="/something", method=RequestMethod.POST)
public String handleSomething(
        @RequestParam String someParam,
        @Account Account account) { ... }

where @Account is my custom annotation.

How can I tell spring to process this annotation?

Use HandlerMethodArgumentResolver (or WebArgumentResolver for versions below 3.1).

To enable your argument resolver:

If you use @EnableWebMvc - make your @Configuration implement WebMvcConfigurer and override addArgumentResolvers()
If you use <mvc:annotation-driven> - use argument-resolvers attribute
For older versions you may need to declare AnnotationMethodHandlerAdapter manually and set its customArgumentResolvers
