  // HttpServletRequest가 넘어옴
  
  //post방식일때 한글 깨지는 것 막음// controller에서 일일이 처리하는 방식은 잘 사용하지 않음 web.xml에서 필터사용
  arg0.setCharacterEncoding("utf-8");
  
  System.out.println("listController 호출");
  System.out.println(arg0.getParameter("data"));

  System.out.println("listController 호출");
  System.out.println(arg0.getParameter("data"));
  
  ModelAndView modelAndView = new ModelAndView();
  modelAndView.setViewName("listview"); //데이터를 보낼 파일명을 적음
  
  //방법 1 - 받은 데이터 넘김
  //arg0.setAttribute("data", arg0.getParameter("data")); 
  
  //방법 2
  modelAndView.addObject("data", arg0.getParameter("data"));
  
  return modelAndView;
 }
