org.mybatis.spring.MyBatisSystemException

在用Id查询时发现所报的异常的记录下来

异常如下：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped Statement 'com.usian.mapper.CategoryMapper.FindCategroyById'.  It's likely that neither a Result Type nor a Result Map was specified.    at 

代码：

Category FindCategroyById(Integer cid);

<select id="FindCategroyById" parameterType="int">        select cname from category where cid = #{cid}</select>

错误原因：

在配置Mapper文件时没有配置resultType属性 再返回类型时无法正确的返回所报的错误
