如何将子域指向特定捆绑包?

如何将子域指向特定捆绑包。我有这个 vhost :

<VirtualHost *:80>
    ServerName subdomain1.mysite.dev
    ServerAlias subdomain2.mysite.dev

    DocumentRoot /mysite/web
    <Directory /mysite/web>
        AllowOverride All
        Order allow,deny
        Allow from All
    </Directory>

</VirtualHost>

这 /etc/hosts :

127.0.0.1       subdomain1.mysite.dev subdomain2.mysite.dev

这个 app/routing.yml :

subdomain1:
    resource: "@ProjectSubdomain1Bundle/Resources/config/routing.yml"
    host: subdomain1.mysite.dev

subdomain2:
    resource: "@ProjectSubdomain2Bundle/Resources/config/routing.yml"
    host: subdomain2.mysite.dev

通过这种方式,两个子域都转到 Subdomain1Bundle .
