我一直在研究如何在spring-boot内设置tomcat，以允许从外部IP地址进行访问。目前，我可以从locahost:port查看UI，但无法从其他系统访问。
http://localhost:8081
当我登录到本地计算机时，它就工作了。
http://192.168.0.93:8081
当我登录到本地计算机并尝试http://192.168.0.93:8081它不起作用。
我想通过另一台计算机的IP地址访问UI，它不起作用。
http://192.168.0.93:8081
当我拿到springs文档时，我发现你可以添加一个IP地址，你希望tomcat在这个地址上设置使用server.address的Web服务器。这样，外部系统就可以通过这个IP地址访问服务器。
server.port=8082
server.address=192.168.0.93
如果我不提供地址，端口工作正常，但当我提供地址并尝试运行它时，我遇到了绑定到该地址的问题。看起来spring-boot已经分配了locahost:8082。
问题：
如何正确设置spring-boot以允许外部地址访问它，并在本地访问时识别它自己的IP？
谢谢

既然有这么多人看过这个问题。解决方案是确保在托管的CentOS计算机上正确配置了防火墙，并且没有明确设置服务器地址。
错误设置
此以前失败，因为防火墙未正确设置
server.port=8081
server.address=192.168.0.93
一旦正确设置了防火墙，就不需要指定服务器地址，只需指定端口。
正确设置
server.port=8081
这使我能够使用其ip从其他系统正确访问该应用程序。
http://<someip>:<server.port>
http://192.168.0.93:8081
谢谢你，你帮我省了很多钱！我想在评论中发布这个，但我没有足够的声誉来回复。
那些想要有关防火墙更改的信息的人，
我使用firewalld在我的vm(centos7)中添加了我的springboot Web服务器端口
我的网络服务器使用8080，所以我使用了：
firewall-cmd --permanent --reload --zone=public --add-port=8080/tcp*
sudo systemctl restart firewalld*
您需要重新启动/重新加载firewalld来应用更改。如果你，
sudo firewall-cmd --list-all*
您可以发现8080/tcp已添加到端口列表中
这可以通过使用ufw轻松完成
要查看当前打开的端口，请输入：sudo ufw status numbered(为了安全起见，请截屏)
要打开端口，请输入：sudo ufw allow 8080(8080或您想要的任何端口)
要删除端口，请输入：sudo ufw delete {number}
在删除之前，请记住用sudo ufw status numbered仔细检查该号码。
：-)
这个问题是由需要打开端口的防火墙引起的。我使用的是ubuntu。这个命令为我打开了端口。我的应用程序使用端口8000，所以我使用下面的命令打开端口
firewall-cmd --permanent --zone=public --add-port=8080/tcp
然后使用命令重新启动防火墙服务
sudo systemctl restart firewalld
还要检查您是否在springboot应用程序中设置了server.servlet.context路径，以了解正确的端点。如果不直接转到端口
