Error running 'Tomcat 9.0.16': Address localhost:8080 is already in use

回答: 当启动Tomcat时出现"Error running 'Tomcat 9.0.16': Address localhost:8080 is already in use"的错误提示，这是因为8080端口已经被占用了。要解决这个问题，可以按照以下步骤进行操作。首先，打开Windows窗口，按下Win+R组合键，然后执行命令"netstat -ano"来查看占用8080端口的进程的PID。\[1\]从查询结果中可以找到占用8080端口的PID，比如16068。接下来，按下CTRL+ALT+DEL组合键打开任务管理器，选择"详细信息"选项卡，在PID列中找到对应的PID，然后结束该进程。最后，重新启动Tomcat即可解决问题。\[2\]
