Spring Boot 不会在端口 80 上启动答案

【问题标题】：Spring Boot won't start on port 80Spring Boot 不会在端口 80 上启动

【问题描述】：

Spring Boot 在默认的 8080 端口上启动正常。每当我尝试在 application.properties 中将端口设置为 80 或使用命令行参数时，都会出现以下错误。将端口设置为 9000 可以正常工作。有什么想法吗？

【解决方案1】：

您想以非特权用户身份访问特权端口吗？你试过在 unix 上以 root 身份运行它吗？

【讨论】：

我没有，这就是问题所在。谢谢。
