Description:

Field userMapper in com.yichao.yichaoadmin.service.user.impl.UserServiceImpl required a bean of type 'com.yichao.yichaoadmin.mapper.user.UserMapper' that could not be found.

Action:

Consider defining a bean of type 'com.yichao.yichaoadmin.mapper.user.UserMapper' in your configuration.

Disconnected from the target VM, address: '127.0.0.1:61973', transport: 'socket'

参考技术A mybatis没有配置对,没有正常注入mapper的bean 参考技术B

主要是这句异常：No qualifying bean of type 'com.yichao.yichaoadmin.mapper.user.UserMapper'

mapper注入有误，就是在业务逻辑层的注入有问题

mapper没有被spring管理起来,看看是否被扫描到了
