整合mybatis，查询数据报错

Question

There was an unexpected error (type=Internal Server Error, status=500).

nested exception is org.apache.ibatis.builder.BuilderException: Error invoking SqlProvider method (tk.mybatis.mapper.provider.base.BaseSelectProvider.dynamicSQL). Cause: java.lang.InstantiationException: tk.mybatis.mapper.provider.base.BaseSelectProvider

这个是什么情况？只要查询数据就出现
