springboot项目创建了BaseMapper继承通用mapper接口，单个业务的mapper继承BaseMapper接口没有问题但是再有一个业务mapper继承baseMapper程序启动就会报错 如下
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'com.dudu.common.mybatis.MyBaseMapper<?>' available: expected single matching bean but found 2: sysRoleInfoMapper,sysUserInfoMapper

你是不是复制粘贴的sysUserInfoMapper这个mapper有两个全局搜下
你的mapper重复了小伙
expected single matching bean but found 2: sysRoleInfoMapper,sysUserInfoMapper
我之前也遇到过，不过我错误的地方是在继承通用控制器BaseController的时候，原因是因为我在BaseController上面添加了注解@Controller，导致其他控制器在引用它的时候，创建了两个相同的BaseController bean，你的情况应该也跟我类似吧，去通用接口BaseMapper上面看看有没有添加什么注解，导致其他接口在引用它的时候创建了两个相同的bean
mapper中没有设置id吧？
