在使用mybaits遇到了如下错误：

1.首先定位问题发生的具体位置，找到了一个函数中参数写法有问题，有问题的函数：
Integer addlastdaystat(Date date,Integer allcount,Integer activecount,Integer isnewcount);
2.修改问题，修改为了：
Integer addlastdaystat(@Param("date")Date date,@Param("allcount")Integer allcount,@Param("activecount")Integer activecount,@Param("isnewcount")Integer isnewcount);
总结：这是由于没有加@param("数据库表中对应的列名")导致的
