我使用SpringDoc

<dependency>
  <groupId>org.springdoc</groupId>
  <artifactId>springdoc-openapi-ui</artifactId>
  <version>1.6.9</version>
</dependency>

使用SpringBoot 2.7.0
SpringDoc配置为使用管理端口（8081），应用程序在8080上运行。

server:
  forward-headers-strategy: FRAMEWORK
  error:
    include-message: always
    include-binding-errors: always
  port: 8080
management:
  server:
    port: 8081
  endpoints:
    enabled-by-default: false
    web:
      exposure:
        include: prometheus,beans,openapi,swaggerui
springdoc:
  use-management-port: true
  swagger-ui:
    display-request-duration: true
    disable-swagger-default-url: true
  show-actuator: true

应用程序运行在反向代理（nginx）之后

upstream app_api {
        server localhost:8080;
}

upstream app_actuator {
        server localhost:8081;
}

server {
    listen 80;
    server_name templates;

    add_header Cache-Control no-cache;
    
    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-Host $host;
    proxy_set_header X-Forwarded-Port $server_port;
    proxy_set_header X-Forwarded-Proto $scheme;

    location / {
        proxy_pass http://app_api;
    }

    location /actuator {
        proxy_pass http://app_actuator;
    }

}

但是当我转到swagger页面时，我可以在主机名后面和生成的curl中看到应用程序端口，但是这个端口在代理后面不应该可见。

我错过了什么？
