spring项目无法启动

Description:

Web application could not be started as there was no org.springframework.boot.web.reactive.server.ReactiveWebServerFactory bean defined in the context.

Action:

Check your application’s dependencies for a supported reactive web server.
Check the configured web application type.

从头到尾查了一遍。项目也不是很复杂，从依赖，版本，到代码都对比了，没啥差但是就是启动报错
也清理了idea的缓存
查了半天最终放弃

结论

没有找到原因，也没有解决，重新开了一个新项目，就没遇到这个报错了

哎 这个也报错
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:3.1.1:deploy (default-deploy) on project reactor: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::url parameter -> [Help 1]
