Apache Kafka Producer Application with Spring Boot

This repository contains a Spring Boot application that acts as a Kafka producer. It demonstrates how to send messages to a Kafka topic using Apache Kafka and Spring Boot. The application runs on port 9191.

Prerequisites

Before running the Kafka producer application, you need to set up a Kafka cluster locally. Follow the steps below to start a Kafka cluster on a Windows setup:

Setting Up Kafka Cluster Locally (Windows)

1. Download and Extract Kafka:

   • Download the latest version of Apache Kafka from the official website: https://kafka.apache.org/downloads
   • Extract the downloaded archive to a directory of your choice.

2. Start ZooKeeper:

   • Open a command prompt and navigate to the Kafka directory.

   • Run the following command to start ZooKeeper:

     bin\windows\zookeeper-server-start.bat config\zookeeper.properties

3. Start Kafka Broker:

   • In a new command prompt window, navigate to the Kafka directory.

   • Run the following command to start the Kafka broker:

     bin\windows\kafka-server-start.bat config\server.properties

4. Create a Kafka Topic:

   • Open another command prompt window and navigate to the Kafka directory.

   • Run the following command to create a topic named "test-topic":

     bin\windows\kafka-topics.bat --create --topic test-topic --bootstrap-server localhost:9092 --partitions 1 --replication-factor 1

   You now have a Kafka cluster running locally with a topic named "test-topic."

Getting Started with Kafka Producer Application

Follow these steps to set up and run the Kafka producer application:

1. Clone the Repository: Clone this repository to your local machine using the following command:

   git clone https://github.com/Ninjavin/Apache-Kafka-Producer.git

2. Configure Kafka Properties:

   • Open the src/main/resources/application.yml file.
   • Update the spring.kafka.bootstrap-servers property to match your Kafka broker's address (e.g., localhost:9092).

3. Build and Run the Application

4. Send Messages:

   • Once the application is running, open Postman and send messages using the URL http://localhost:9191/producer-app/publish/{message} to send messages.
