dhslrl321/cqrs-journey-guide-korean

This system is an educational and reference implementation of the CQRS (Command Query Responsibility Segregation) and Event Sourcing patterns, built with Java and Spring Boot. It provides a structured codebase that demonstrates core domain models, command handlers, and event-driven architectures for managing conference registrations and orders. The project includes both a 'journey' module for step-by-step learning and 'reference' modules for deeper architectural examples, supported by Gradle build configurations and documentation.

A new README file for the 'Part 02. CQRS References' section has been added, providing a table of contents link and a list of six reference links covering CQRS patterns, Event Sourcing, and related architectural topics.

The project now includes the Gradle wrapper script (gradlew) and its associated configuration files (gradle-wrapper.properties), enabling users to build the project using a specific, pinned version of Gradle (7.5) without requiring a pre-installed JDK or Gradle. Additionally, a .gitignore file was added to exclude IDE-specific files (IntelliJ, NetBeans, VS Code) and build outputs, and a README.md was added to describe the source code's purpose.

New markdown files were added to the 'part03-tale' directory, introducing detailed case studies for Twilio and Lokad Hub. These documents outline architectural lessons learned, such as separating read and write models and leveraging event sourcing, providing users with real-world examples of CQRS and DDD implementations.

Introduced new classes to support event-driven architecture for seat management. This includes the \Event\ and \VersionedEvent\ interfaces, an \AbstractVersionedEvent\ base class, and specific event classes like \AvailableSeatsChanged\ which carries a list of \SeatQuantity\ objects to represent changes in seat availability.

Added the core event-sourcing infrastructure and domain models for the chapter 4 reference implementation. This includes the \AbstractEventSourced\ base class that manages event handlers, versioning, and pending events, along with supporting types like \EventSourced\ interface, \VersionedEvent\, \Action\, and \Type\. It also introduces the \Order\ aggregate with an \updateSeats\ method, and related domain classes such as \OrderItem\, \OrderUpdatedEvent\, and \SeatQuantity\. Additionally, a basic \User\ model was added to the user package.

Added the foundational Java classes for a CQRS-based conference registration system. This includes the Spring Boot application entry point, domain models for conferences, orders, and events, and controllers for handling registration and conference lookup endpoints. The change introduces the core structure for processing seat reservations and managing order states.

The write model now includes the Order aggregate with state transitions (CREATED, BOOKED, REJECTED) and an event-sourcing foundation via AggregateRoot and EventPublisher interfaces. Additionally, a new RegistrationProcessManager has been added to handle order placement by initiating seat reservations, supported by the OrderPlaced event and related process state definitions.

Adds the foundational classes for the command pattern in the order domain. This includes a generic \CommandHandler\ interface and an \OrderCommandHandler\ that routes specific commands (such as \RegisterToConference\, \MarkSeatsAsReserved\, \RejectOrder\, \ConfirmOrder\, and \AssignRegistrantDetails\) to their respective handlers. The diff also introduces the \Command\ interface and empty placeholder classes for the various commands, alongside domain classes like \Order\ and \EventSourcedRepository\.

New Gradle build files have been added to configure the project structure, including a root build.gradle, a Spring Boot-based 'journey' module, and multiple 'reference' modules for chapters 3 and 4. The 'journey' module is configured with Spring Boot 2.7.2, JPA, Web, and H2 dependencies, while the 'reference' modules use Java with JUnit 5.8.1 and Lombok 6.5.1. The settings.gradle file defines the multi-project structure, including subprojects for 'journey' and 'reference' chapters.
