显示mapper找不到：Field xxxMapper in xxx required a bean of type ‘xxxMapper‘ that could not be found

Field flowerMapper in cn.clearnight.flower.service.impl.FlowerServiceImpl required a bean of type 'cn.clearnight.flower.mapper.FlowerMapper' that could not be found.

 这个问题可能是由于导包出现问题,如 2.7.1 出现问题,换成 2.7.2 或者其它版本可以解决问题

改完后,运行成功!!
