Full-stack reactive Spring Kafka app using Hilla

This is an example application showing how to produce and consume Kafka messages in a Spring Boot application using Spring Kafka and Hilla.

Installing Kafka

The application is configured to use a local Kafka broker. You can use a managed solution like Confluent by updating application.properties appropriately.

1. Download Kafka from the Kafka website
2. Extract the archive
3. Start Zookeeper with bin/zookeeper-server-start.sh config/zookeeper.properties
4. Start the Kafka broker with bin/kafka-server-start.sh config/server.properties

Running the application

1. Make sure you have Kafka running (see above)
2. Run the app with the included Maven wrapper ./mvnw, or by running the Application Java class.
