1. Java 17+
"java --version" on the command line must return a version 17 java like:
openjdk 17.0.9 2023-10-17
OpenJDK Runtime Environment Homebrew (build 17.0.9+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.9+0, mixed mode, sharing)
There are two main modules
i. product-service
- when a product is created, the server responds with 201 and adds the location of the resource in the "Location" header of the response
- if product exists, it returns conflicted httpstatus
ii. event-update-listener
- product-service starts a web service with exposed api's for product manipulation,saves to postgres.
- product-service also serves as the kafka producer that publishes any change in product to a kafka topic
- when an http request comes to create a product, immediately the product is successfully created,
a product payload is published to "product.created" topic, when an update http request comes in, a payload is published to "product.updated" topic,
when a delete http request comes in, product deleted is published to "product.deleted"
- event-update-listener is a subscriber to the topics that are published by product service and it also stores the information in mongodb.
rename ".example.env" file to ".env" [this loads the values into docker]
docker-compose builddocker-compose upthis above starts kafka and zookeper, starts two services(product-service and event-update-listener) and starts two databases, mongo_db and postgres_db
[/product-service-http-requests.postman_collection.json] contains all CRUD http requests to use in PostMan
Swagger URL :
Kafka-UI to view kafka updates as changes happen in real-time http://localhost:8090/
CI/CD : Jenkinsfile is placed in product-service to deploy to heroku
./mvnw clean./mvnw testthis runs integration and unit tests with 100% class coverage using testcontainer for integration and mocks for unit service tests
