spring The request sent by the client was syntactically incorrect() issue

Question

I am getting exception mentioned in subject line. Could you please explain what is wrong:

package mvc;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/req")
public class Req {
@RequestMapping(method = RequestMethod.GET)
@ResponseBody
public String get(@RequestBody String body) {
    return body;
}
}

SpringMVC-servlet.xml

Thanks, Sandip

You're not sending anything in the GET request body ([it doesn't make much sense, anyway](http://stackoverflow.com/q/978061/1240557)), so Spring can't bind anything via `@RequestBody`. What did you expect to see in the `body` value in your controller code? — kryger, Apr 17 '15 at 11:24
I want to check how RequestBody works. You mean RequestBody annotation won't work for GET? I will try for POST method. — Sandip Gaikwad, Apr 17 '15 at 11:38
use POST instead of GET. And right now you are not providing any data in HTTP request body. — John, Apr 17 '15 at 11:41

Change method to POST and send some data with HTTP POST so the (@RequestBody String body) binding works.

You could use SoapUi or HTTP Requester plugin for browsers to conveniently send HTTP POST.

Otherwise define method as:

@RequestMapping(method = RequestMethod.GET)
@ResponseBody
    public String get() {
        return "Some string";
    }
