Nginx と Spring Boot の連携

Spring boot が ssl 利用してない場合、nginxの設定ファイルを以下のようにすればよいです。

nginx.conf

http {
    upstream server_com {
 	   server 127.0.0.1:8081;
    }
   
    server {
        listen       80;
	listen       [::]:80;
        server_name  localhost;

	location / {
	    proxy_http_version 1.1;
            proxy_pass      http://server_com;
            proxy_set_header        X-Forwarded-For   $remote_addr;
            proxy_set_header        X-Real-IP         $remote_addr;
            proxy_set_header        Host              $host;
            proxy_set_header Access-Control-Allow-Origin *;
            proxy_read_timeout 900;
	}	
    }

}

spring boot が ssl　を利用する場合、

nginx.conf

http {
    
   
    server {
        listen       80;
	listen       [::]:80;
        server_name  localhost;
	#return       301 https://$host:4433$request_uri;
    }

	upstream server_com {
 	   server 127.0.0.1:8443;
    }


    # HTTPS server
    server {
        listen       4433 ssl;
	listen      [::]:4433 ssl;
        server_name  localhost;

        ssl_certificate      /path/to/cert.pem;
        ssl_certificate_key  path/to/cert.key;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

        location / {
            proxy_pass      https://server_com;
            proxy_set_header        X-Forwarded-For   $remote_addr;
            proxy_set_header        X-Real-IP         $remote_addr;
            proxy_set_header        Host              $host;
            proxy_set_header Access-Control-Allow-Origin *;
            proxy_read_timeout 900;
	}
    }
}
