Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException:

根据提供的引用内容，可以看出Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException是由于在Spring容器中重复定义了同一个bean导致的异常。这通常发生在两个或多个bean具有相同名称和类型的情况下。解决此问题的方法是删除重复定义的bean或更改其名称或类型以使其唯一。

这似乎是一个Java Spring Boot应用程序的异常，根据异常信息，出现了无法加载MySQL驱动程序的错误。这可能是因为应用程序没有正确配置MySQL驱动程序或者缺少MySQL驱动程序。您可以检查应用程序配置文件，确保已正确配置MySQL驱动程序，并且MySQL驱动程序已正确添加到应用程序的依赖项中。

这个错误是由于 Spring 框架在创建 'bizFactory' bean 时出现了依赖不满足的问题。具体的错误信息是 'brand' bean 的查找方法解析失败，原因是无法内省 Class [com.fmall58.wechatsub.business.bizs.BrandHelper]。

可能的原因之一是 'BrandHelper' 类没有正确的配置或实现了一个无效的查找方法。请确保 'BrandHelper' 类正确实现了正确的查找方法，并检查是否有任何其他相关的配置或依赖缺失。

另外，你还可以检查 'BrandHelper' 类所在的包是否正确地被扫描并注册为 Spring bean。如果没有正确配置包扫描，Spring 将无法识别 'BrandHelper' 类并创建相应的 bean。

希望这些信息对你有帮助，如果还有其他问题，请随时提问。
