Kafka PoC (Proof of Concept)

This project demonstrates a simple setup for using Apache Kafka with Spring Boot applications.

Overview

The project consists of the following modules:

• kafka-poc: Parent POM project that manages common configuration and dependencies.
• kafka-message-consumer: Spring Boot application responsible for consuming messages from Kafka.
• kafka-message-producer: Spring Boot application responsible for producing messages to Kafka.
• kafdrop: Dockerized Kafka UI for monitoring Kafka topics and messages.

Prerequisites

Before running the applications, ensure you have the following installed:

• Java 17
• Apache Maven
• Docker

Setup

1. Clone the repository:

   git clone https://github.com/mehdiz/kafka-poc.git

2. Navigate to the project directory:

   cd kafka-poc

3. Build the project using Maven:

   mvn clean install

4. Start Kafka and Kafdrop using Docker Compose:

   docker-compose up -d

5. Open your browser and navigate to http://localhost:3000 to access the React app.

6. To send a greeting message, use curl:

   curl http://localhost:8081/send/greeting/[name]

   Replace [name] with the desired name for the greeting message.

That's it! Kafka, Kafdrop, and the React app are now running, and you can send greeting messages to the Kafka message consumer using curl.
