Make sure to run mvn package before beginning, and make sure to include a book in plain text named "fichier.txt" at the root of the project.
Open a first terminal, name it "kafka server" and run:
kafka-server-start.sh /opt/kafka/config/kraft/server.properties
Open a 2nd terminal, name it "producer lines-stream" and run:
kafka-console-producer.sh --bootstrap-server localhost:9092 \
--topic lines-stream
Open a 3rd terminal, name it "producer command-topic" and run:
kafka-console-producer.sh --bootstrap-server localhost:9092 \
--topic command-topic
Open a 4th terminal, name it "TextLinesToWordsStream", and run:
java -cp target/tp-kafka-0.0.1-SNAPSHOT.jar if4030.kafka.TextLinesToWordsStream
Open a 5th terminal, name it "WordsLemmatizerStream", and run:
java -cp target/tp-kafka-0.0.1-SNAPSHOT.jar if4030.kafka.WordsLemmatizerStream
Open a 6th terminal, name it "CategoryWordCounter", and run:
java -cp target/tp-kafka-0.0.1-SNAPSHOT.jar if4030.kafka.CategoryWordCounter
In the terminal "producer lines-stream", run the command:
cat fichier.txt | kafka-console-producer.sh --bootstrap-server localhost:9092 \
--topic lines-stream
wait a few seconds, and go in the terminal called "producer command-topic", and run:
END
It should output in the terminal of "CategoryWordCounter" the 20 most used categories of the book "fichier.txt", along with the 20 most used lemmas within each of these 20 categories.
To test the app, I used the book "La Guerre des Mondes": https://fr.wikisource.org/wiki/La_Guerre_des_mondes It resulted in this output from the app CategoryWordCounter:
