How to disable kafka in spring boot

Disabling Kafka in Spring Boot

In order to disable Kafka integration in a Spring Boot application, you can follow these steps:

1. Remove Kafka dependencies from your project’s build file (e.g., pom.xml for Maven or build.gradle for Gradle). Here’s an example of how to remove Kafka dependencies in a Maven project:

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-kafka</artifactId>
</dependency>

2. Exclude Kafka auto-configuration from Spring Boot. You can achieve that by adding the following exclusion to your main application class:

@SpringBootApplication(exclude = { KafkaAutoConfiguration.class })

This will prevent Spring Boot from automatically configuring Kafka beans.

3. Remove any Kafka-related configuration properties from your application.properties or application.yml file. For example, you might have properties like this:

spring.kafka.bootstrap-servers=localhost:9092
spring.kafka.consumer.group-id=my-group-id

Remove these properties to disable Kafka integration.

By following these steps, Kafka integration will be disabled in your Spring Boot application. You can remove Kafka-specific logic and dependencies from your code.

Here’s an example of how your main application class would look like after disabling Kafka:

@SpringBootApplication(exclude = { KafkaAutoConfiguration.class })
public class MyApp {
  public static void main(String[] args) {
    SpringApplication.run(MyApp.class, args);
  }
}

Note that after disabling Kafka, any code or components that depend on Kafka may need to be modified or removed accordingly.
