Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type '' available: expected at least 1 bean which qualifies as autowire candidate.

问题描述

Spring报错：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type '' available: expected at least 1 bean which qualifies as autowire candidate.

解决方法：

查看spring扫描的表，是否包含Mapper接口的文件夹。

比如，在配置文件中配置：

<context:component-scan base-package="com.xxx"/>

那么 Mapper接口就只能写在 com.xxx 文件夹下面，否则spring扫描不到这个 Mapper接口，就会报错。
