Tomcat rewrite url to redirect IP to domain name

Heya,

I think you shouldn’t be trying to use such a redirect on the Application level. I think you look for this to be done on Apache.

Since you are using Tomcat, I’ll assume you are using Apache as a reverse proxy infront of it(let me know if that is not the case).

Create a Virtual Host for your domain: Create a new configuration file for your domain in the /etc/apache2/sites-available directory:

sudo nano /etc/apache2/sites-available/your-domain.conf

Replace your-domain with your actual domain name.

Configure the Virtual Host: Add the following configuration to the newly created file, replacing your_domain.com and your_server_ip with your domain and server IP address, respectively:

<VirtualHost *:80>
    ServerName your_domain.com
    ServerAlias www.your_domain.com
    
    ProxyPreserveHost On
    ProxyPass / http://localhost:8080/
    ProxyPassReverse / http://localhost:8080/
</VirtualHost>

<VirtualHost *:80>
    ServerName your_server_ip

    RewriteEngine On
    RewriteRule ^(.*)$ http://your_domain.com$1 [R=301,L]
</VirtualHost>

In this configuration, the first VirtualHost block sets up a reverse proxy, forwarding requests to your domain to your Tomcat server running on localhost:8080. The second VirtualHost block redirects all requests made to the server IP to your domain.

Enable the Virtual Host: Enable the new Virtual Host configuration and restart Apache:

sudo a2ensite your-domain.conf
sudo systemctl restart apache2

After completing these steps, all requests made to your server IP should be redirected to your domain name. Additionally, your Apache server will act as a reverse proxy, forwarding requests to your domain to your Tomcat server running on localhost:8080.
