springboot启动失败,报端口被占用

Question

在本地启动时没有问题!上服务器(阿里的centos)后,启动后报错:
java.io.FileNotFoundException: class path resource [templates/] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/root/java/jiyaoNewWeb-1.0.jar!/BOOT-INF/classes!/templates/

报这个问题之后,又继续跑了一段:最后告诉我说启动失败,说443可能被占用,我用lsof -i:看了没有在用的,现在也用的是root账号,端口也是开放了的:
最后的报错信息是:
2019-04-29 15:50:33,891 [main] DEBUG org.springframework.boot.diagnostics.LoggingFailureAnalysisReporter - 
Application failed to start due to an exception

org.springframework.boot.context.embedded.tomcat.ConnectorStartFailedException: Connector configured to listen on port 443 failed to start

Answer 1

搞定了! 是nginx占用了! 但是不知道为什么lsof -i:或者grep不到! 之前没有怀疑是因为同事说他用的是8082,最后我自己去看了下,其实还是用的80,所以导致启动不了,

Answer 2

用netstat -ant | grep 443 看看呢

Answer 3

不一定是端口的问题吧，你看下这个报错。java.io.FileNotFoundException: class path resource [templates/] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/root/java/jiyaoNewWeb-1.0.jar!/BOOT-INF/classes!/templates/

Answer 4

估计是你启动了tomcat，查查看
