在嘗試用80埠啟動springboot應用時，console報錯如下：

Description:

The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 80, or configure this application to listen on another port.
 

經排查，80埠並沒有被佔用，後來在StackOverflow上得知普通使用者無法使用1024以下的埠號

文中也提供了幾種解決方法
