A query was run and no Result Maps were found for the Mapped Statement 'com.atguigu.dao.TravelItemDao.find_group_itemByItemId'. It's likely that neither a Result Type nor a Result Map was specified.

翻译：

原因：org.apache.ibatis.executor.executor异常：运行了查询，未找到映射语句“com.atguigu.dao.TravelItemDao.find_group_itemByItemId”的结果映射。很可能既没有指定结果类型，也没有指定结果映射。

 

是吧，翻译过来就很明显了，应该是Dao的xml映射文件里面 的那个语句没有写返回值，（如下图）

 

 争取的应该是这样
