bean注入失败：已经卡了好几天了

Question

spring boot bean注入失败（springboot使用的是2.7版本）：已经卡了好几天了

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'baseMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.jason.project_one.mapper.UserMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Answer 1

userController需要注入userServiceImpl，后者需要UserMapper，应该是UserMapper有问题，检查一下，或者贴出代码
