Springboot service deployed in AKS not working with ingress - spring-boot

Question

I have a simple Springboot service, which works well when I configure Service of type:LoadBalancer. But when I use service of type:ClusterIP and introduce ingress, it does not work
For that matter, I am unable to get Ingress working for any of my deployments in Azure/AKS.
Please suggest what am I missing
Spring code
#RestController
#RequestMapping("/demo")
public class MyController {
#GetMapping("/welcome")
public String welcome() {
return "Hello Welcome";
}
}
