java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for com.**.bank.dao.AmountMapper.selectQueryAccount
出现这个错误有网上说的：命名空间没写对，如果使用mapper，则
<mapper namespace="com.sitech.mapper.StudentMapper">
空间中一定要写上Mapper的名称，否则就会报错。
还有一个情况就是interface的名称和你xml的名称没有一致造成的，我是这种情况，新手开发。。。
比如你mapper的名称为AmountMapper 但是xml的名称为AmountMapper_sqlMap.xml这个是ibatis2的惯用写法。。。
