ajax post - controller return값

fn_coupon_reload() 메서드를 호출하고 싶은데 delBarcode.do 에서 404 오류가 떠서 호출이 안되고 있었음 .

 

 

function fn_delete_barcode(id){
		 $("#barcodeId").val(id);
		 if(confirm("해당 상품권을 삭제하시겠습니까?")){
			 $.post('<c:url value="/reservation/manage/delBarcode.do"/>', $("#frm").serialize())
			 .done(function(data) {
				    fn_coupon_reload()
				})
				.fail(function(jqXHR, textStatus, errorThrown) {
				    if (jqXHR.status === 404) {
				      console.error("오류 발생:", textStatus, errorThrown);
				    }
				});
		 }
	 }

1.

@ResponseBody

붙여주기

 

 

2.

JSONObject json = new JSONObject();

Map<String, Object> result = new HashMap<String, Object>();

 

String resultCode = "";

String message ="";

 

리턴해줄 json과 resultCode, message 선언

 

3.

resultCode = "200";

성공 코드 지정.

 

catch (NullPointerException e) {

// 2023-07 (SW 보안취약점 조치)

logger.error(e.getMessage(), e);

resultCode = "500";

} finally {

response.setContentType("text/html; charset=UTF-8");

PrintWriter out = null;

try {

logger.info("result[{}]", json.toString());

out = response.getWriter();

out.print(json);

out.flush();

} catch (NullPointerException e) {

// 2023-07 (SW 보안취약점 조치)

logger.error(e.getMessage(), e);

} catch (Exception|Error e) {

logger.error(e.getMessage(), e);

} finally {

if(out != null) out.close();

}

}

return;

}

 

 

catch - finally 에서 리턴해줄 값 지정
