for more details about the project, please check the attached pdf document "Walkthrough_SpringBoot_Microservices_Project"

To Run the project :

download axon server : https://download.axoniq.io/axonserver/AxonServer.zip then run it and run rabbitmq via docker:

cd AxonServer
java -jar axonserver.jar
docker run --rm -it -p 15672:15672 -p 5672:5672 rabbitmq:3-management

then run each microservice independently(Command microservice, Query microservice, Discovery Server and APIGateway).

then run elasticsearch with docker

sudo docker run -p 9200:9200-e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.10.0

To test the app

send post request: with the following body

http://localhost:8087/product
{
    "title":"souris",
    "price":1000,
    "quantity":2
}

get data via this api

http://localhost:8082/products-query-service/products

download link :

https://download.axoniq.io/axonserver/AxonServer.zip

extract the file and run

cd AxonServer
java -jar axonserver.jar

RabbitMQ message broker is used to assure an asynchronous communication between the Command microservice and the Query microservice
