Spring Applications

Exercise: Booking Application

1. Create a Postgres database booking.
2. Implement a transactional travel service that allows customers to make travel bookings that consist of a flight and a hotel booking:
   • Flights and hotels are booked separately by the booking service
   • If one booking fails, the whole travel booking is canceled
   • The booking attempts and possible failures are logged using the logging service
3. Set the following logging levels to observe the transaction management to DEBUG.

logging.level.org.springframework.transaction.interceptor.TransactionInterceptor
logging.level.org.springframework.orm.jpa.JpaTransactionManager

4. Run the TravelServiceIT integration test to test the service.
