springboot2.0應用啓動報錯

在嘗試用80端口啓動springboot應用時，console報錯以下：

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端口並無被佔用，後來在StackOverflow上得知普通用戶沒法使用1024如下的端口號

文中也提供了幾種解決方法
