我试图在 Spring STS 的localhost上启动一个tomcat v9.0服务器，但是它会弹出以下错误。
“在localhost启动tomcat v9.0服务器遇到了问题”
没有任何进程使用端口8080.所以这不应该是端口8080正在使用另一个进程。尝试更改端口，但它一次又一次地给出相同的错误。有人可以帮助我克服这个错误。
控制台中显示以下错误。

答案 0 :(得分：0)
在eclipse中启动tomcat服务器之前必须验证的两件事。
港口可用性：
如果已经使用了tomcat服务器端口，请终止这些进程
windows：netstat -aon | find / i“listening”| find“port_num”
taskkill / F / PID“这里从上一个命令得到的PID”
Linux：sudo netstat -plten | grep java
杀死-9“这里你从以前的commanand得到的PID”
您可以在conf文件夹的server.xml中找到tomcat服务器端口。
Apache常用日志库。
大多数servlet初学者都不知道添加Apache常用日志库。从这里下载罐子：
https://commons.apache.org/proper/commons-logging/download_logging.cgi
在这些进程尝试启动apache tomcat服务器之后。我希望这对你有所帮助。
