How can use Zuul gateway with Spring boot 3? [duplicate] - spring-boot

Question

I am trying create a Zuul Api gateway for my microservices.
It also has the eureka disovery client.
Here is the application class
ZuulServerApplication.java
package com.ftr.zuul;
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;
#SpringBootApplication
#EnableZuulProxy
#EnableDiscoveryClient
public class ZuulServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZuulServerApplication.class, args);
}
}

I am getting the following error while trying to run the application.
***************************
APPLICATION FAILED TO START
***************************
Description:
Field optionalArgs in org.springframework.cloud.netflix.eureka.EurekaClientAutoConfiguration$RefreshableEurekaClientConfiguration required a bean of type 'com.netflix.discovery.AbstractDiscoveryClientOptionalArgs' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.netflix.discovery.AbstractDiscoveryClientOptionalArgs' in your configuration.
It is working fine without the Zuulserver but when I add the zuul dependency I get this error.
How to resolve this issue?

Answer 1

Reverting back to Spring Boot 2.7.7 is the only thing that has worked for me so far, so if you're able to do that then it's probably the easiest solution:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.7</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
I realise this isn't a great long-term fix, though. I'll keep looking and update this if I find anything better.
