## How to run

First start the docker-compose which contains ZooKeeper, Kafka, Kafdrop, and MySQL.

```bash

$ docker-compose -f docker-compose.yml up -d

```

Once all the containers are healthy start the application,

```bash

$ ./mvnw spring-boot:run

```

Open the browser `localhost:8080/apidocs`. 

You can interact with the `random` API to create a random user which then will be sent to Kafka and consumed by the consumer (see [`consumer/UserKafkaListener.java`](https://github.com/kasramp/spring-kafka-test/blob/master/src/main/java/com/madadipouya/springkafkatest/consumer/UserKafkaListener.java) file) and finally saves into the database.

To see whether the message has been sent to Kafka, open your browser `http://localhost:8085/topic/com.madadipouya.kafka.use` (Kafdrop environment), 

you should be able to see all messages that sent to `kafka.user` topic.

To run Flyway migration scripts only run,

```bash

$ ./mvnw flyway:migrate

```
