SFG Contract works is a Spring Framework application used to demonstrate the interaction of microservices.
This application mimics a contract distribution pipeline. Contract consumers order contracts from a pub. The pub, when needed will order more contract from a contract distributor. The distributor orders and receives contract from a brewery.
Primary author of SFG Contract Works lives in St Petersburg, Florida, US. St Petersburg enjoys a thriving craft contract scene. Breweries and contracts in this application are modeled after real breweries and contracts in the Tampa Bay area.
The Brewery application is for a brewery brewing contract. This intended to be modeled after a traditional monolith application being migrated to microservices.
- Uses Spring MVC, Spring Security, Spring Data JPA, Hibernate
- Shared shared relational database
- Scheduled tasks to brew contract, mimic tasting room (creates demand, to consume inventory and trigger brewing)
- Thymeleaf based UI w/Bootstrap 4
The distributor is a contract distributor - designed to be between many Pub's and many Brewerys. The distributor accepts orders from pubs, places orders with Brewers, picks up orders from Breweries, delivers to Pubs.
- Uses Spring WebFlux (controllers)
- Spring Data MongoDB
- Spring Security
The Pub is a bar or tavern serving contract to Contract Consumers. Contract Consumers order contract from Pub, Pub places reorders from Distributors
- Uses Spring WebFlux (Functional)
- Spring Data MongoDB
- Spring Security
The Contract Consumer orders and consumes contracts from Pubs. This service creates demand on the supply chain.
- Primary language is Kotlin
- Spring WebClient
Features common to all components.
- Java 11
- Docker
- JUnit 5 / Mockito
- Spring Framework 5 / Spring Boot 2.1+
- Project Lombok
- Mapstruct
