用gson得JSON，数值变为double类型 ，去掉double值中的小数位（3.0改为3）

// 缓存中取
		String json = _jedisClient.get("RICHER_TRAN_RECORDS_GIVE"+user.getId());
		if (StringUtils.isNotBlank(json)){
			resultMap = new Gson().fromJson(json, new TypeToken<Map<String,Object>>(){}.getType());

// 方式一 ： gson转换默认是double类型  ,去掉70.0 这种数据的小数位
			Set<String> keySet = resultMap.keySet();
	        for(Iterator<String> it = keySet.iterator();it.hasNext();){
	            String key = it.next();
	            if(resultMap.get(key) instanceof Double){
	            	resultMap.put(key, ((Double)resultMap.get(key)).intValue());
	           }else{
	        	   List<Map<String, Object>> list = (List<Map<String, Object>>)resultMap.get(key);
	        	   for(Iterator<Map<String, Object>> mapIt = list.iterator();mapIt.hasNext();) {
	        		   Map<String, Object> map = mapIt.next();
		               Integer format = ((Double)map.get("format")).intValue();
		               map.put("format", format);
		          }
	           }
	        }
