This is the Java/Spring version of the Event Sourcing/CQRS money transfer example application.
This application consists of three microservices:
- Account Service - the command side business logic for Accounts
- Money Transfer Service - the command side business logic for Money Transfers
- Query service - query side implementation of a MongoDB-based, denormalized view of Accounts and MoneyTransfers
The Account Service consists of the following modules:
- commandside-backend-accounts - the Account aggregate
- commandside-web-accounts - a REST API for creating and retrieving Accounts
The Money Transfer Service consists of the following modules:
- commandside-backend-transactions - the MoneyTransfer aggregate
- commandside-web-transactions - a REST API for creating and retrieving Money Transfers
The Query Service consists the following modules:
- queryside-backend - MongoDB-based, denormalized view of Accounts and MoneyTransfers
- queryside-web - a REST API for querying the denormalized view
In order to be used with the embedded Event Store, the three services are currently packaged as a single monolithic web application:
- monolithic-web - all-in-one, monolithic packaging of the application
As well as the above modules there are also:
- common-backend - code that is shared between the command side and the query side, primarily events and value objects
- backend-integration-tests - integrations tests for the backend
