nginx mutiple domain with ssl and www redirection

nginx redirection is not working as expected with ssl and
www redirection.

I have two domains
say, domain1.com and domain2.com. I need to have https with www redirection on both ie
https:/www.domain1.com. and
https:/www.domain2.com.

but when i take
www.domain2.com its redirected to
https:/www.domain1.com.

Please see the
configurations

domain1.com

server
            {
 listen 8080;

 server_name domain1.com;

            return 301 https://www.domain1.com$request_uri;
}

server
            {
 listen 443 default_server;
 ssl on;
 ssl_certificate
            /root/ssl/dom1/unified.crt;
 ssl_certificate_key
            /root/ssl/dom1/my-private-decrypted.key;


 root
            /var/www/dom1.com/html;
 index index.php index.html
            index.htm;

 server_name www.domain1.com;


            }

            https://www.domain2.com$request_uri;
}
