在尝试使用Spring Boot Actuator时遇到启动错误，表现为ApplicationContextException，具体原因指向一个NullPointerException。问题源于springfox库在处理请求处理器排序时的一个空指针异常。尽管尝试了网上的多种解决方案，但问题仍未解决，目前选择临时注释掉Actuator依赖以使项目正常启动。进一步的故障排查和修复可能需要更新或排除与springfox或Actuator相关的依赖冲突。

问题如下

在添加了 actuator 的依赖之后，启动springboot 项目会报错，暂未找到解决办法
网上各种说法试过之后还是为解决，直接先注释掉，不是啥大功能
