报错信息

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'noticeController': Unsatisfied dependency expressed through field 'noticeService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'noticeServiceImpl': Unsatisfied dependency expressed through field 'baseMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.ajie.zndcxtwxapi.mapper.NoticeMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

解决

添加@Mapper注解

就是因为没有扫描到Mapper类导致报错

在启动类添加 MapperScanner（）指定包名也可以。
