    @ResponseBody
    public DeviceList getdevicelist(HttpServletRequest request, HttpServletResponse response) {
        

        String m_unit=request.getParameter("khnuit");
        m_unit=EncodingTool.encodeStr(m_unit);
        DeviceList ds=new DeviceList(deviceService.find(m_unit),1,0,20);
        return ds;
    }
    public static class EncodingTool {  
        public static String encodeStr(String str) {  
            try {  
                return new String(str.getBytes("ISO-8859-1"), "UTF-8");
