解决ConflictingBeanDefinitionException报错

问题遇到的现象和发生背景

SSM框架整合,一直报bean类指定注释的bean名'log'与同名和类的现有的、不兼容的bean定义冲突。但找了半天也没找到叫log。

运行结果及报错内容
org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'log' for bean class [com.mysql.cj.log.Log] conflicts with existing, non-compatible bean definition of same name and class [com.alibaba.druid.support.logging.Log]

我的解答思路和尝试过的方法

百度查询了原因,clean 重启什么的都没用
有没有人可以控屏帮忙找下原因?
