类型转换错误java.math.BigDecimal cannot be cast to java.lang.String

数据库获取统计参数sum()统计值，在代码转化为Integer 时，提示转换失败：java.math.BigDecimal cannot be cast to java.lang.String

解决办法：

	List set= util.excuteQuery("select COALESCE(sum(1),0) as times from wlsq_data.home_pet_feeder_timing where gateway_id=? and timing_id=? and del_flag=0  ", objs); 
		if(set !=null && set.size() >0){ 
			for(Object obj:set){			 
				HashMap<String, Object> map =(HashMap<String, Object>)obj;					 
					Integer str = Integer.parseInt(map.get("times").toString()); 
					if(str == 0){ 
				    	result = 0; 
				    }else{ 
				    	result = str; 
				    } 
				 
				 
			}		 
			     
										 
		}
