         }else if(valueObj instanceof Long[]){
            Long[] values = (Long[])valueObj;
            for(int i=0;i<values.length;i++){
               value = values[i] + ",";
            }
            value = value.substring(0, value.length()-1);
         }else if(valueObj instanceof int[]){
            int[] values = (int[])valueObj;
            for(int i=0;i<values.length;i++){
               value = values[i] + ",";
            }
            value = value.substring(0, value.length()-1);
         }
         else{
            value = valueObj.toString();
         }
         returnMap.put(name, value);
      }
   }
   return returnMap;
}

遇到坑：前端传入数组，接收的变量Long[] ，导致加密验签失败
