Spring @RequestBody Content type not supported

Controller:

@RestController
public class ExampleCtrl {
    @RequestMapping(name="/example", method=RequestMethod.POST)
    public String example(@RequestBody String request) {
        System.out.println("example: " + request);
        return "OK";
    }
}

And request (linux console):

curl -i -X POST 'https://localhost/example' -k -d 'name=value'

And spring console output:

example: name=value

But when I use @RequestBody Request request instead of @RequestBody String It doesn't work:

@RestController
public class ExampleCtrl {
    @RequestMapping(name="/example", method=RequestMethod.POST)
    public String example(@RequestBody Request request) {
        System.out.println("example: " + request);
        return "OK";
    }
}

@JsonIgnoreProperties(ignoreUnknown=true)
class Request {
    private String name;

    public Request() {}

    public String getName() {
        return name;
    }
}

I have exception:

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported

EDIT Resolved. It works when I use

curl -i -X POST 'https://localhost/example' -k -d '{"name": "value"}' --header "Content-Type:application/json"

according to Spring documentation:

You convert the request body to the method argument by using an HttpMessageConverter. HttpMessageConverter is responsible for converting from the HTTP request message to an object and converting from an object to the HTTP response body. The RequestMappingHandlerAdapter supports the @RequestBody annotation with the following default HttpMessageConverters:

ByteArrayHttpMessageConverter converts byte arrays.

StringHttpMessageConverter converts strings.

FormHttpMessageConverter converts form data to/from a MultiValueMap.

SourceHttpMessageConverter converts to/from a javax.xml.transform.Source.

so perhaps the request argument is not a simple String (Specially you are using POST) and couldn't be converted.
