I wasn't able to autowire org.asynchttpclient.AsyncHttpClient in my Spring Web project

I have the following @RestController which makes POST request. I am able to Autowire and make REST calls with Resttemplate but when I try to use AsyncHttpClient, Spring complains about ClassNotFoundException even if I did autowire the class and provided the Bean in the same class.

I also have applicationl.properties file that allows circular for now reference(spring.main.allow-circular-references=true)

I am using Spring Boot start 2.7.8 and asnyc-http-client 2.12.3

I am not sure what I am missing here. May be the way I created the HttpClient isn't right ?

package com.example.demo.controller;

import java.io.IOException;
import org.asynchttpclient.AsyncHttpClient;
import org.asynchttpclient.DefaultAsyncHttpClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
@Component
public class WebhookListener {
    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) {
        // Do any additional configuration here
        return builder.build();
    }

    @Bean
    public AsyncHttpClient asyncHttpClient() {
        // Do any additional configuration here
        return new DefaultAsyncHttpClient();
    }

    @Autowired
    private RestTemplate restTemplate;

    @Autowired
    private AsyncHttpClient client;

    @PostMapping("/parasol/registerhook")
    public void createWebhook() {

        System.out.println("starting....");

        // AsyncHttpClient client = new DefaultAsyncHttpClient();
        client.prepare("POST", "https://alchemy-sdk-core-example.com/create-webhook")
                .setHeader("accept", "application/json")
                .setHeader("X-Alchemy-Token", "abc...333")
                .setHeader("content-type", "application/json")
                .setBody(
                        "{\"AddressWebhookParams\":{\"addresses\":[\"0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D\",\"0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9\"],\"network\":\"ETH_MAINNET\"},\"url\":\"https://bda7-2600-1700-87d3-9200-edc9-c4f5-5ad9-1f14.ngrok.io/parasol/accountlistner\",\"type\":\"ADDRESS_ACTIVITY\"}")
                .execute()
                .toCompletableFuture()
                .thenAccept(System.out::println)
                .join();

        try {
            client.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

Below is the exception:

Looks like the AsyncHttpClient is not available in your classpath. Ensure your pom is free from typo asnyc-http-client(as in the question above).

<dependency>
    <groupId>org.asynchttpclient</groupId>
    <artifactId>async-http-client</artifactId>
    <version>2.2.0</version>
</dependency>
