How consume Kafka message from different server using spring boot microservices - spring

Question

We have an application that sends the message let say "Hello world" from one spring boot server let say the server port number is 8080 and we need to send this message to the other server using Kafka which at the port number 8090. How to consume those services on 8090 port server. Can you please suggest what I did wrong on this
Producer running on 8080 port
package com.xerox.pps.Kafka.services;
import java.io.IOException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Source;
import org.springframework.kafka.annotation.KafkaListener;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.stereotype.Service;
#Service
#EnableBinding(Source.class)
public class KafkaProducer {
private Source mySource;
private static final Logger logger = LoggerFactory.getLogger(KafkaProducer.class);
#Autowired
private KafkaTemplate<String, String> kafkaTemplate;
String kafkaTopic = "java_in_use_topic";
public void send(String message) {
logger.info(String.format("#### -> Producing message -> %s", message));
kafkaTemplate.send(kafkaTopic, message);
}
#KafkaListener(topics = "hello_world_topic1", groupId = "java_in_use_topic-0")
public void consume(String message) throws IOException {
logger.info(String.format("#### ->Recived message -> %s", message));
}
}
