脚本宝典收集整理的这篇文章主要介绍了mybatis参数格式化异常:NumberFormatException: For input string:"xx"，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
使用Mybatis注解开发的时候，总会遇到很多问题，但是mybatis的注解并不是那么的美好，一些问题或者错误根本不能给出准确的定位，有时候，甚至会给出Unknow Source的错误，获取就是一个关闭标签没有关上。此类问题，在xml配置中，mybatis做的比较好，所以，官方也不是很放心其注解，建议使用XMl。

这段代码，就是mybatis的动态查询，就是组装sql语句。但是，这里必须注意一个问题，那就是startd和endd,这两个变量是ShareChannelStInfo中的私有变量，是String类型的。
错误的引起，是startd != 0和endd != 0引起的，原因给的是字符串，却拿一个数字比较，mybatis会做一些转化，结果在数字格式化时发生异常。
