我没有任何用于前端的 html 文件.我只想上传部署 api 以共享来自 swagger ui 的文档.

I do not have any html files for front-end. I just want to upload deploy the api to share the documentation from swagger ui.

推荐答案

这是因为服务器正在侦听 5000，将server.port=5000"添加到 application.properties 解决了该问题.

It's because server is listening to 5000, Adding "server.port=5000" to application.properties fixed the issue.
