Error running ‘Tomcat 9.0.27’: Address localhost:1099 is already in use

在启动tomcat的时候报端口被占用的错误，导致web项目无法运行。解决办法如下：

1.cmd命令提示符号，执行命令：netstat -ano
可见，占用1099端口的进程的PID是10460。
Error running 'Tomcat 9.0.27': Address localhost:1099 is already in use

可见，占用1099端口的进程的PID是12888。

2.命令提示符号，执行命令：tasklist

Error running 'Tomcat 9.0.27': Address localhost:1099 is already in use

可见，该占用8080端口的进程是Java.exe
不过绝大部分占用的都是java.exe

3.通过任务管理器，终止进程java.exe

4.重新启动tomca/或者重新打开一个工程，即可正常启动
