Failed to get response of head request

[Mkabaka]

Expected behavior

When I send a head request in postman, there is a Parse Error: The server returned a malformed response occurred.

Actual behavior

I expect the response of get which has no entity content.

Steps to reproduce

Define a controller that looks like this:

@Controller
@RequestMapping("/")
public class SimplePlainController {

    @RequestMapping("/12345")
    @ResponseBody
    public String list() {
        return "Hello";
    }

}

and then send a simple head request as: http://127.0.0.1:9997/12345.
