org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Could not set property 'pNo' of 'class mis.data.entity.mis.OrderAllocationSub' with value 'K16242A' Cause: java.lang.IllegalArgumentException: argument type mismatch
数据库中的pNo字段是varchar(8);
我xml文件中用的是string,为何还会出异常?
