Ticket app that creates pdf ticket with QR-code

! The project is not yet completed and still is in the development phase. In the next releases, it is planned to decompose the ticket-payment service into occasion-service and ticket-order-service and add a message broker for implementing a saga pattern. I also plan to separate qr-code generation into a separate service and add functionality to read QR-codes. In addition, I plan to launch the project on AWS and replace CircleCi to Jenkins. !

Languages and Tools:

Spring Boot, Spring Cloud, Hibernate Jpa, Lombok, MySql.

Service	Port	CI
ticket-payment	8084
pdf-generator	8083
currency-exchange	8082
bank-simulator	8081

Hibernate JPA was used instead of Spring Data JPA for learning purpose. Before app launch you must have JDK 11 and MySql server installed on your machine.

Within selection, the api will calculate the ticket price according to the seat and date.

GET localhost:8084/api/v1/occasions/1000000001

Result (reduced for readability):

You can use filters and pagination to retrieve data you need:

GET localhost:8084/api/v1/occasions?ticket_type=TRAIN_INTERCITY&ticket_type=CONCERT_STADION&occasion_seats_from=30&size=3&page=0&sorting_order=DESC&sorting_field=occasionId

Result:

Fetch available filters:

localhost:8084/api/v1/occasions/filters

Result:

With selected Occasion you can create a pdf ticket with a qr-code. Default currency is "usd" but you can use another currency instead of "usd" for example "uah". In this case service will make a request to currency-exchange server and it will convert the currency you specified into "usd" according to the current exchange rate. e.g.:

POST localhost:8084/tickets


{
    "customerTicketDto": [{
	 "firstName": "firstName2",
	 "lastName" : "lastName2",
	 "country"  : "Fiji", 
	 "seat" : 10,
	 "amount" : "51.00",
	 "seatPlaceType" : "CONCERT_CLUB_BALCONY"
	}],
    "ticketType" : "CONCERT_CLUB",
    "occasionAddress" : "Hard Rock Cafe London Picadilly Circus",
    "occasionDate" : "2023-11-22 22:10",
    "occasionName" : "Concert - Eric Clapton",
    "bankAccount": 2548870,
    "currency" : "usd"
}

Api will return created TicketOrderId. It can be used generate pdf tiket with QR-code:

GET localhost:8084/api/v1/tickets/PDF/3000000001

ticket-payment service will read TicketOrder from DB and will perform a request to pdf-generator to generate a pdf ticket for every Customer.
