See the answer https://stackoverflow.com/a/19599143/1524502, and note the issues about being behind a reverse proxy or load balancer. Most likely, that is your problem.
请参阅答案https://stackoverflow.com/a/19599143/1524502，并注意有关落后于反向代理或负载均衡器的问题。最有可能的是，那是你的问题。
The answerer in that question recommended using
该问题的回答者建议使用
request.getHeader("x-forwarded-proto")
instead, though that is dependent on your load balancer setting the header correctly.
相反，尽管这取决于您的负载均衡器正确设置标头。

If your server is running behind a proxy server, make sure your proxy header is set:
如果您的服务器在代理服务器后面运行，请确保设置了代理标头：
proxy_set_header X-Forwarded-Proto $scheme;
Then to get the right schemeyou can use springframework's classes:
然后为了得到正确的scheme你可以使用 springframework 的类：
HttpRequest httpRequest = new ServletServerHttpRequest(request); //request is HttpServletRequest
UriComponents uriComponents = UriComponentsBuilder.fromHttpRequest(httpRequest).build();
String scheme = uriComponents.getScheme(); // http/https

I used to have a similar problem with getScheme()
我曾经对 getScheme() 有类似的问题
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
I've solved using "//" instead:
我已经使用“//”解决了：
String basePath = "//"+request.getServerName()+":"+request.getServerPort()+path+"/";
