jsonp java 구현시 jQuery was not called 나오는 경우

 호출 하는 곳 

function checkBal(){

var url ="http://1.1.1.1/Search/check?callback=?"

$.ajax({

url: url,

type : "GET",

dataType: "jsonp",

data: {'id': 'test'},

jsonpCallback:"callback",

success: function(data) {

console.log('callback success');

},

error:function(request,status,error){

console.log("code:"+request.status+"\n"+"message:"+request.responseText+"\n"+"error:"+error);

}

})

서버쪽

@RequestMapping(value = "/check", method=RequestMethod.GET)

@ResponseBody

public void request(@RequestParam String spcBizNo, @RequestParam String callback,HttpServletResponse response) throws IOException {

Map<String, String> paramMap = new HashMap<String, String>();

System.out.println("callback spcBizNo====="+spcBizNo);

System.out.println("callback spcBizNo====="+callback);

paramMap.put("id", id);

paramMap.put("result", "success");

String result = null;

ObjectMapper mapper = new ObjectMapper();

try {

System.out.println("callback spcBizNo====="+resData.getTemp());

paramMap.put("stat_cd", resData.getTemp());

result = mapper.writeValueAsString(paramMap);

logger.info("result111={}", result);

result = callback + "(" + result + ")";

logger.info("result22222={}", result);

response.getWriter().print(result);

} catch (JsonGenerationException e) {

e.printStackTrace();

} catch (JsonMappingException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return 방식으로 하는 경우 callback was not called 가 발생.

try catch 로 감싸서 보내니 성공 했다.

원인은 알아볼 시간이 없다
