I am trying create a Zuul Api gateway for my microservices. It also has the eureka disovery client.

I am using Spring Boot 3 and Zuul 1.0 starter.

Here is the application Zuul Gateway class.

ZuulGatewayApplication.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;


@EnableDiscoveryClient
@EnableZuulProxy
@SpringBootApplication
public class ZuulGatewayApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZuulGatewayApplication.class, args);
    }

}

pom.xml configuration

</project>

I am getting the following error while trying to run the application.
