public boolean preHandle(HttpServletRequest request, HttpServletResponse response) request 데이터가져오기

HttpServletRequest request가 어떻게 들어오는지 보고싶을때 사용가능.

하나하나 getParameter 처럼 받아오는게 아니고 json전체가 어떻게 들어오는지 볼수있음.

if ( request.getMethod().equals("POST") )
        {
            StringBuffer sb = new StringBuffer();
            BufferedReader bufferedReader = null;

            try {
                bufferedReader =  request.getReader() ; //new BufferedReader(new InputStreamReader(inputStream));
                char[] charBuffer = new char[128];
                int bytesRead;
                while ( (bytesRead = bufferedReader.read(charBuffer)) != -1 ) {
                    sb.append(charBuffer, 0, bytesRead);
                }

            } catch (IOException ex) {
                throw ex;
            } finally {
                if (bufferedReader != null) {
                    try {
                        bufferedReader.close();
                    } catch (IOException ex) {

                    }
                }
            }

            log.info("my test {}",  sb.toString());
        }
