간단한 현재시간 찍기
  long startTime = System.currentTimeMillis();    
  System.out.println("Job 시작 시간 : "+ new Timestamp(startTime));

현재시간 가져오기 : SimpleDateFormat 이용
 Calendar calendar = Calendar.getInstance();
 SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmssSSS");
 System.out.println("현재 시간 : " + dateFormat.format(calendar.getTime())); 

public static String readClobData(Reader reader) throws IOException {
        StringBuffer data = new StringBuffer();
        char[] buf = new char[1024];
        int cnt = 0;
        if (null != reader) {
            while ( (cnt = reader.read(buf)) != -1) {
                data.append(buf, 0, cnt);
               
            }
        }
        return data.toString();
    }


if(rs.next()){
   String clobData = readClobData(rs.getCharacterStream("CONTENT"));
   content = new String(clobData.getBytes("utf-8"), "utf-8");
   actionForm.setContent(content);
  }
  //GET LOB DATA
