mybatis和spring整合时报错Error instantiating interface spring.dao.GoodsDao with invalid types () or values

报错：org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Error instantiating interface spring.dao.GoodsDao with invalid types () or values (). Cause: java.lang.NoSuchMethodException: spring.dao.GoodsDao.()

是dao的mapper文件中的的返回类型写错了

应该是查询goods实体类而不是返回了dao类
