400 (Bad Request) while sending json in Spring

I'm trying to send json string to Spring controller, i'm getting 400 - bad request as response

i'm using Spring 4.0.3

This is my controller

@Controller
public class Customer{

    @RequestMapping(value = "/apis/test", method = RequestMethod.GET, produces = "application/json")
    public @ResponseBody String test(HttpServletRequest params) throws JsonIOException {
        String json = params.getParameter("json");
        JsonParser jObj = new JsonParser();
        JsonArray  jsonObj = (JsonArray ) jObj.parse(json);

        for(int i = 0; i < jsonObj.size(); i++) {
            JsonObject jsonObject = jsonObj.get(i).getAsJsonObject();
            System.out.println(jsonObject.get("name").getAsString());

        }
        return json;
    }
}

Please help me to solve this

@RequestMapping(value = "/apis/test", method = RequestMethod.GET, produces = "application/json")

The above means this is a HTTP GET method which does not normally accept data. You should be using a HTTP POST method eg:

@RequestMapping(value = "/apis/test", method = RequestMethod.POST, consumes = "application/json")
    public @ResponseBody String test(@RequestParam final String param1, @RequestParam final String param2, @RequestBody final String body) throws JsonIOException {

then you can execute POST /apis/test?param1=one&param2=two and adding strings in the RequestBody of the request

I hope this helps!
