Wildcard Subdomain In SpringBoot For my Mac

1 answer

I am creating a web application in which there will be multiple subdomain. Each client will be having its own subdomain. Each subdomain will have individual database. For example I am having a client abc, then it will have subdomain as abc.mydomain.com and its database name will be abc.

Now this application is created in spring boot. Here I want to configure wildcard subdomain. So how can I configure it in spring boot. For this, I had tried few solution.

I had changed my /etc/hosts and added an domain name entry in it as below

127.0.0.1 www.mydomain.com

But now I want subdomain in this. How can I do it.

I had seen somewhere that I need to configure server.xml of tomcat. In server.xml I had added below line.

<Host name="www.mydomain.com"  appBase="webapps" unpackWARs="true" autoDeploy="true">     <Alias>*.mydomain.com</Alias> </Host> 

Can you please help me with this. Also let me know incase you need more details in this.

The best answer:

After been working for multiple days I came to a solution for this question. As I was working for wildcard subdomain in localhost. Thus for this I need to use an external software called dnsmasq, I had executed following commands to install dnsmasq in my laptop.

brew install dnsmasq

After installing dnsmasq in my laptop I need to to configure it. For this I have to update the dnsmasq. For my case it is located at

/usr/local/etc/dnsmasq.conf

In this file I have to add few lines to configure wildcard subdomain. Lines are as below.

# Route all *.mydomain.com addresses to localhost address=/mydomain.com/127.0.0.1 # Don't read /etc/resolv.conf or any other configuration files. no-resolv # Never forward plain names (without a dot or domain part) domain-needed # Never forward addresses in the non-routed address spaces. bogus-priv 

Next I need to restart my dnsmasq service. Command for it is as below.

sudo brew services start dnsmasq

Finally you need to create a file mydomain.com at /etc/resolver (Create folder resolver if not exists). Add below line in mydomain.com file.

nameserver 127.0.0.1

This is the complete configuration for setting up swildcard subdomain in your mac os.
