Building Kafka Consumers
Develop Spring Kafka consumers to subscribe to and process messages from Kafka topics.
Kafka Consumers: The Listeners
In event-driven architectures, Kafka Consumers are the components responsible for reading messages (records) from Kafka topics. Think of them as listeners waiting for new events!
They subscribe to one or more topics and process the incoming data, enabling different parts of your application or other services to react to events.
Spring Boot & Kafka Config
To build a Kafka consumer in Spring Boot, first, you need the spring-kafka dependency. Add it to your pom.xml:
<dependency>
<groupId>org.springframework.kafka</groupId>
<artifactId>spring-kafka</artifactId>
</dependency>Next, configure your Kafka broker details in application.properties. This tells your Spring Boot app where to find the Kafka server.
