Welcome to Apache Kafka and Spring Boot Integration for producer as well as consumer.

Please visit https://kafka.apache.org/quickstart for running the instance of kafka and zookeeper.

In case if you are not able to get to the URl then below are the details:

1. To start the zookeeper

bin/zookeeper-server-start.sh config/zookeeper.properties

2. to start the kafka cluster server

bin/kafka-server-start.sh config/server.properties

3. to manually create a new topic

bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test (replace test with your topic name)

4. to list the topics

bin/kafka-topics.sh --list --zookeeper localhost:2181 (This will display topics list)

5. to send a msg using producer

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test(replace test with your topic name)

6. to see the consumer consuming the message

bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning(replace test with your topic name)

7. Remember to read about the group(s) in kafka, very useful information

https://cwiki.apache.org/confluence/display/KAFKA/Consumer+Group+Example

8. To delete the msgs from producer

seq 0 | ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic Kafka_Example_json

replace the number after seq to delete those number of msgs. Msgs after that number will be retained. Before that number will be deleted from queue.

My code uses lombok to avoid biler plate code.

There is active information in the code for your information.

Enjoy !!!
