Spring boot 在spring引导中重定向时，错误https变为http，端口为443

我使用nginx为我的springboot项目配置ssl，我使用它创建sslcer。 当我准备创建新记录时，我的路径仍然是https

但是，当我单击SaveChanges时，在成功创建之后，重定向以返回到列表页面，返回路径变成http，端口443

    @PostMapping("/create")
    @PreAuthorize("{@appAuthorizer.authorize(authentication, 'INSERT', this)}")
    public String create(Locale locale, Model model, @ModelAttribute("category")  Category category,
                     BindingResult result){
    try{
        if(categoryService.addNew(category)){
            return "redirect:/admin/category/list?page=1";
        }
        return "categories/add-category";

    }catch (Exception e){
        return "error";
    }

这是我的nginx配置

upstream ecommerce_service {
    server          localhost:8023;
}
server {
    listen 80;

    server_name         ecommerce-hieutm.tk www.ecommerce-hieutm.tk;
    return 301 https://ecommerce-hieutm.tk$request_uri;
}
server {

listen  443 default ssl;
server_name ecommerce-hieutm.tk www.ecommerce-hieutm.tk
root        /var/www/html/;

ssl_certificate    /etc/nginx/certificate_ca_bundle.crt;
ssl_certificate_key    /etc/nginx/private.key;
#server_name ecommerce-hieutm.tk www.ecommerce-hieutm.tk

access_log /var/log/nginx/ecommerce.access.log;
error_log /var/log/nginx/ecommerce.error.log;

    location / {
            root            /var/www/html/;
            index           index.html;
            proxy_pass      http://ecommerce_service;
            proxy_set_header   Host             $host:$server_port;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_pass_request_headers  on;
            proxy_pass_header Server;
            proxy_set_header X-NginX-Proxy true;
            proxy_redirect off;

    }

这是一个错误

有人能帮我吗，谢谢
