How to redirect to a controller or a web page from localhost:8080/ in spring boot 3.1.1 with server.servlet.contextPath

I have a requirement that in case of localhost:8080 , it should point to a default web page in spring Boot application. Currently I am using Spring Boot 3.1.1. Normally everything works, but I add server.servlet.contextPath=my-service, it does not work. I provide below the code.

My Controller Code

@RestController
public class DefaultController {
    
	@GetMapping(path = "/")
	public ResponseEntity<String> getValue() {
		return ResponseEntity.ok("Hello World");
	}

    @GetMapping(path = "/info")
	public ResponseEntity<String> getInfoValue() {
		return ResponseEntity.ok("Some Information");
	}
}

I have also tried with the following @Configuration option.

@Configuration
public class WebMVCApplicationConfig implements WebMvcConfigurer {

    @Override
   public void addViewControllers(ViewControllerRegistry registry) {
       registry.addRedirectViewController("/", "/my-service/info");
   }
}

If I comment the following in application.properties, everything works fine.

# server.servlet.contextPath=/my-service

If I uncomment the contextPath, I get HTTP Status 404 – Not Found

Please suggest me. I want to redirect to a web page along with contextPath. If someone is accessing localhost:8080, it should redirect to localhost:8080/my-service/info.

Please help me.

This code may be useful which I got from stackoverflow. This code satisfies my requirement. The link is given below.
