任何意见都是非常感谢的！谢谢大家!

不确定mybatis spring扫描是否支持通配符。您是否已尝试显式定义映射器

<bean id="userLoginDAO" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="...myMapperInterface" />
    <property name="sqlSessionFactory" ref="sqlSessionFactoryBean" />
</bean>

“找不到[com.example.dao.IUserLoginDAO]类型的符合依赖项条件的bean：至少需要1个符合此依赖项autowire候选项条件的bean。”您错过了

IUserLoginDAO

bean。如果它用@Component注释，请检查它是否在扫描组件的包中。
