问题：

Error building SqlSession.

The error may exist in com/kuang/dao/StudentMapper.xml

Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. The XML location is ‘com/kuang/dao/StudentMapper.xml’. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias ‘Student’. Cause: java.lang.ClassNotFoundException: Cannot find class: Student

解决方法：
在核心配置文件中配置：

<typeAliases>
        <typeAlias type="com.kuang.pojo.User" alias="User"/>
</typeAliases>
