b201819-ms-event-sourcing

This is an e-commerce application with a microservice-architecture and the event-sourcing pattern implemented. There are a total of 5 microservices which are:

• Customer Service
• Rating Service
• Inventory Service
• Order Service
• Invoice Service

Requirements

• Java 1.8+
• NPM (version used in development is 6.4.1)
• docker-compose (tested with v1.2.3)
• docker (tested with v18.09)

Installation

First clone the JHipster Registry from their repository https://github.com/jhipster/jhipster-registry

$ git clone https://github.com/jhipster/jhipster-registry.git

Start the registry

$ cd jhipster-registry
$ mvnw (or ./mvnw with linux)

This application is using Kafka as an event store. Therefore kafka and docker has to be started. After docker is running you can run kafka with:

$ docker-compose -f kafka.yml up

(it is rare but it can happen that starting kafka fails, then just try again until there is no error message )

After the JHipster Registry and Kafka is running you can start the API Gateway and the microservices. It is recommended to start the API Gateway first. The first time running mvnw on the shop might fail. Just try again and it should work fine.

$ cd shop
$ mvnw (or ./mvnw with linux)
$ npm start

Start the microservices

$ cd customers/orders/ratings/invoices/inventory
$ mvnw (or ./mvnw with linux)
