eclipse出现：Several ports (8005, 8080, 8009) required by Tomcat v8.5 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).

第一:

window10系统:任务管理器里面查找Java进行结束

其他系统也可以进行查找下!

在处理完成后，重新启动即可

第二:

使用eclipse的时候出现这个问题：

这是因为已经启动了tomcat，只是在eclipse里面看不到。

这时只需要找到tomcat的目录，在bin文件夹里面找到shutdown.bat执行一下，再去eclipse里面启动tomcat就成功了！
