Content negotiation in Spring MVC

Question

I am writing a RESTful web application with Spring 3, and part of my application needs to process the data according to the requested media type.

@RequestMap         


        

Answer 1

Although skaffman's answer is correct, I found in the latest Spring release (3.1 M2), there is an alternative and better way to do this, using consumes and produces values:

@RequestMapping(value="/pets", consumes="application/json")
public void addPet(@RequestBody Pet pet, Model model) {
    // ...
}

@Controller
@RequestMapping(value = "/pets/{petId}", produces="application/json")
@ResponseBody
public Pet getPet(@PathVariable String petId, Model model) {
    // ...
}

Update:

Here are the official Spring documentation about this:
