java - learning Spring's @RequestBody and @RequestParam

Question

I'm editing a web project that uses Spring and I need to adding some of Spring's annotations. Two of the ones I'm adding are @RequestBody and @RequestParam. I've been poking around a little and found this, but I still don't completely understand how to use these annotations. Could anyone provide an example?

Answer 1

Controller example:

@Controller
class FooController {
    @RequestMapping("...")
    void bar(@RequestBody String body, @RequestParam("baz") baz) {
        //method body
    }
}

@RequestBody: variable body will contain the body of the HTTP request

@RequestParam: variable baz will hold the value of request parameter baz
