尝试把 reactor-netty 版本升级到 0.9.4.RELEASE
结果又出现 spring-webflux 版本不兼容

还原最初版本，最后把 Spring Cloud 版本降级到Hoxton.SR1，运行成功，结果出现新坑，Nacos又出现版本不兼容问题，没办法最后找到 Spring Cloud Alibaba 官方推荐配置，修改Spring Boot、Spring Cloud、Spring Cloud Alibaba 版本，运行成功

Spring Boot 版本：2.3.2.RELEASE
Spring Cloud 版本：Hoxton.SR8
Spring Cloud Alibaba 版本：2.2.5.RELEASE

附上 Spring Cloud Alibaba 官方推荐版本地址
推荐版本
