对于Map<String, Object>中时间类型的值进行格式化操作

    for (Map<String,Object> formap:map){
      Set keyset = formap.keySet();
      Date time=null;
      String modifykey=null;
      for(Object key:keyset){
        boolean isInstance = formap.get(key) instanceof Date;
        if (isInstance){
            String formatTime=DateUtil.format((Date) formap.get(key),"yyyy-MM-dd HH:mm:ss");
             time=DateUtil.parse(formatTime);
             modifykey=String.valueOf(key);
        }
      }
      if (time!=null) {
        formap.put(modifykey, time);
      }
     
    }
