Spring Mvc and MediaType for consumes in @RequestMapping for a get rest request

I'm implementing a REST application using Spring Boot. I want to specify the consumes parameter for the @RequestMapping annotation. The rest call should be something like:

http: // mysite.com/resource/123

In the controller I handle this as follows:

    @RequestMapping(value = "/resource/{id}", method = RequestMethod.GET, 
consumes = XXX, produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public Scenario getResource(@PathVariable("id") final long id) {
        //...
    }

The default value, i.e. all, is obvious and not specific. So, which should be the correct MediaType for consumes?

It depends on your requirements. If you only want to allow consumption of JSON, for example, then:

@RequestMapping(consumes = MediaType.APPLICATION_JSON_VALUE, ...)

If you want to consume multiple media types, then you can specify them in an array:

@RequestMapping(consumes = {
        MediaType.APPLICATION_JSON_VALUE,
        MediaType.APPLICATION_XML_VALUE,
}, ...)

To consume data from url path or url query param, you don't need to explicitly specify any media format. It works with the default format.

@RequestMapping(value={"/resource/{id}"}, method={RequestMethod.GET})
public String getResource1(@PathVariable("id") Long id){
    // other code here
    return "";
}

@RequestMapping(value={"/resource/{id}"}, method={RequestMethod.POST})
public String getResource2(@PathVariable("id") Long id, @ModelAttribute Person person){
    // other code here
    return "";
}

With just a path variable, you do not need any content type. If you leave it blank, Spring will map all /resource/{id} requests to this handler regardless of the content type header. If you want to specify a content type, choose a default one like text/plain. But be aware that you have to change the request to have the same content-type header.

According to the documentation, consumes has to match the value of Content-Type header so the value you need to send for the mapping depends on what the client sets in the header.
