Build the Demo

Here is how to build it:

git clone git@github.com:bootique-examples/bootique-kafka-producer.git
cd bootique-kafka-producer
mvn package

Run the Demo

Now you can check the options available in your app:

NAME
      bootique-kafka-producer-0.0.1-SNAPSHOT.jar

OPTIONS
      -b host:port, --bootstrap=host:port
           Single Kafka bootstrap server.

      -c yaml_location, --config=yaml_location
           Specifies YAML config location, which can be a file path or a URL.

      -h, --help
           Prints this message.

      -H, --help-config
           Prints information about application modules and their configuration options.

      -t topic_name, --topic=topic_name
           Kafka topic to write data to.

To test this example, you will need a Kafka broker release 0.10.0.0 and a topic to write some string data into it. Run Zookeeper and Kafka broker both on localhost from Kafka root directory:

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

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

Run kafka-console-consumer.sh script to read string data from a topic:

bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic topic 

Run the producer:

java -jar target/bootique-kafka-producer-0.0.1-SNAPSHOT.jar --bootstrap=localhost:9092 --topic=topic
