spring boot request.getRequestURL()无法获取https

Question

我的项目是nginx+spring boot，，弹簧启动端口为8080在我使用nginx转发后，request.getRequestURL()只能得到http而不能得到https

public static String  getRootUrl(HttpServletRequest request){
StringBuffer url = request.getRequestURL();
String tempContextUrl = url.delete(url.length() - request.getRequestURI().length(), url.length()).append(request.getSession().getServletContext().getContextPath()).append("/").toString();
return tempContextUrl;
}

nginx配置了https

server {
listen         80;
server_name    xx.xxx.xx; 
add_header Strict-Transport-Security max-age=15768000;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl; 
server_name xx.xxx.xxx; 
keepalive_timeout 10m;
ssl_certificate      cert.pem; # 
ssl_certificate_key  cert.key; # 
ssl_session_timeout 24h;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location / {
proxy_pass http://127.0.0.1:8080;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port $server_port;
add_header Content-Security-Policy upgrade-insecure-requests;
}
}

你的nginx代理到8080端口，这个应用程序是一个集成的tomcat服务器，你没有在这个tomcat中配置SSL，所以，在应用程序内部，它是http，你可以在spring引导中配置SSL。
