BlueZone

An example application implementing Hexagonal Architecture

See the article series: [https://jmgarridopaz.github.io/content/hexagonalarchitecture-ig/intro.html]

BlueZone allows car drivers to pay remotely for parking cars at zones in a city, instead of paying with coins using parking meters.

• Users (driver actors) of the application are car drivers and parking inspectors.

  • Car drivers will access the application using a Web UI (User Interface), and they can do the following:

    • Query all the available rates in the city, in order to choose the one of the zone he wants to park the at.
    • Purchase a parking ticket, paying an amount of money for parking a car at a zone, during a period of time. This period starts at current date-time. The ending date-time is calculated from the paid amount, according to the rate of the zone.

  • Parking inspectors will access the application using a terminal with a CLI (Command Line Interface), and they can do the following:

    • Check whether a car is illegally parked at a zone. This will happen if there is no valid ticket for the car and the rate of the zone. A ticket is valid if current date-time is between the starting and ending date-time of the ticket period.

• Driven actors needed by the application are: a rate repository, a ticket repository, and a payment service.

Development environment:

• Java 9 (jdk-9.0.4)

• Maven 3.5.4

• IntelliJ IDEA 2021.3.3 (Community Edition)

• Ubuntu 20.04.4 LTS (Linux 5.13.0-40-generic)

Instructions:

• Download and extract this github repo to a local directory on your computer ( <bluezone_dir> )

• Compile all modules (you need to do this just the first time before running):

  cd <bluezone_dir>
  ./scripts/build.sh
  

• Run the entry point to the app:

  • "for parking cars" test driver:

    cd <bluezone_dir>
    ./scripts/run_startup_forparkingcars.sh
    

  • "for checking cars" test driver:

    cd <bluezone_dir>
    ./scripts/run_startup_forcheckingcars.sh
