pdp-spring-core

project for resolving tasks from Spring Core module in scope of preparing to assesment.

Task

Create a Spring-based module, which handles event ticket booking.

Rules:

• Implement three service classes: UserService, EventService, Ticket service. Which should contain user, event, and booking-related functionality accordingly. Create an implementation of the BookingFacade interface which should delegate method calls to services mentioned above.
• Implement DAO objects for each of the domain model entities (User, Event, Ticket). They should store in and retrieve data from a common in-memory storage - java map. Each entity should be stored under a separate namespace, so you could list particular entity types.
• Storage should be implemented as a separate spring bean. Implement the ability to initialize storage with some prepared data from the file during the application start (use spring bean post-processing features). Path to the concrete file should be set using property placeholder and external property file.
• DAO with storage bean should be inserted into services beans using auto wiring. Services beans should be injected into the facade using constructor-based injections. The rest of the injections should be done in a setter-based way.
• Cover code with unit tests.
• Code should contain proper logging.
