ivangfr/axon-springboot-websocket

This system is a food ordering application built on an event-driven, CQRS architecture using the Axon Framework and Spring Boot. It manages customer, order, and restaurant domains through distinct microservices that handle command processing, event sourcing, and real-time WebSocket updates. The codebase includes comprehensive test coverage and automated environment management scripts to support development and deployment workflows.

11 changes.

This period focused on migrating the codebase to an event-driven, CQRS architecture using the Axon Framework, introducing new services for food ordering and restaurant management. The work involved significant refactoring of existing services, updating build tooling and dependencies, and modernizing the frontend with Tailwind CSS and WebSocket integration.

7 changes.

This period focused on establishing a robust domain-driven architecture by introducing comprehensive event models and refactoring service packages to align with a new namespace. Significant effort was also dedicated to increasing test coverage for both customer and food ordering services, alongside the addition of utility scripts and documentation diagrams.

The project now includes shell scripts (\init-environment.sh\, \build-docker-images.sh\, \start-apps.sh\, \stop-apps.sh\, \remove-docker-images.sh\, \shutdown-environment.sh\) to automate the lifecycle of the development environment. These scripts handle starting and stopping Docker containers for Axon Server, MySQL, PostgreSQL, and MongoDB, as well as building and running the Spring Boot applications. Additionally, \.editorconfig\ and \.gitattributes\ files have been added to enforce consistent code formatting and Git behavior across different operating systems.

The application now enforces a strict separation between command (write) and query (read) models using Axon Framework. The \customer-service\ exposes REST endpoints to manage customers and their orders, projecting events into a JPA-backed read model. The \food-ordering-service\ introduces an \OrderAggregate\ to handle order creation and a repository projector to sync order state, while the \restaurant-service\ manages restaurant and dish entities with corresponding aggregates and projectors. Additionally, WebSocket handlers were added across services to broadcast real-time updates for customer, order, and restaurant events, and logging interceptors were introduced to trace command and event dispatching.

The axon-event-commons module now includes a comprehensive set of domain event classes for tracking changes to customers, orders, and restaurants. This includes specific events for adding, updating, and deleting customers, as well as order creation events containing item details. For restaurants, the module provides events for adding, updating, and deleting restaurants, along with specific events for adding, updating, and deleting menu items (dishes). These classes serve as the foundational data structures for the application's event-driven architecture.

A new food-ordering-service is introduced, providing a multi-step order placement wizard and real-time updates via WebSocket. The frontend, located in static/app.js, implements a state-driven wizard flow for orders and subscribes to STOMP topics for customers, restaurants, and dishes. The UI displays order details including formatted currency and dates, and shows a live connection status indicator.

The customer service interface has been updated with a new visual style using Tailwind CSS classes, replacing the previous styling approach. Additionally, the JavaScript logic for managing customer data and WebSocket connections has been refactored to use the Stomp.js library for WebSocket communication and the dayjs library for date formatting, improving how connection status is displayed and how order details are rendered in the customer list.

The customer service interface has been rebuilt using Tailwind CSS for styling, replacing the previous framework. The template now includes a navigation bar with a WebSocket connection status indicator, a customer management form, and a customer list. The page also features custom confirmation and alert modals for user interactions. Additionally, the frontend dependencies have been updated to use jQuery 3.7.1, SockJS Client 1.6.1, STOMP.js 7.3.0, Day.js 1.11.18, and Accounting.js 0.4.1.

The customer-service application configuration has been converted from YAML (application.yml) to the standard Java properties format (application.properties). This change includes the addition of environment variable placeholders for database credentials and Axon Server host/port, the removal of the Spring Boot Actuator and SpringDoc/Swagger UI configuration blocks, and the removal of the banner text. Users will see the service start with the new configuration structure, which may affect how environment variables are used for sensitive data and removes previously exposed actuator endpoints.

The order placement flow has been redesigned as a multi-step wizard that guides users through selecting a customer, restaurant, dishes, and a final review. The interface has been restyled using Tailwind CSS, replacing the previous styling framework, and includes a visual step indicator to track progress through the four stages of the order process.

The customer-service module has been migrated from the com.mycompany package to com.ivanfranchin.customerservice. New Axon 4.5.14 interceptors (CommandLoggingDispatchInterceptor, EventLoggingDispatchInterceptor) and their configuration (AxonConfig) have been added to log command dispatches and event publications. The ErrorAttributes bean was updated to use Spring Boot 4.0.6's webmvc-specific classes and exclude EXCEPTION from error attributes. Several classes were renamed or repurposed (e.g., CustomerDeletedEvent to GetCustomerOrdersQuery, DishPk to OrderItem) to align with the new package structure and domain model.

The food-ordering-service has been refactored to use the \com.ivanfranchin\ package namespace, replacing the previous \com.mycompany\ structure. This change includes renaming classes to better reflect their domain roles (e.g., \OrderDto\ to \Order\ model, \OpenOrderCommand\ to \CreateOrderCommand\) and moving files into more specific sub-packages (e.g., \customer\, \order\, \restaurant\). Additionally, the \ErrorAttributesConfig\ was updated to use the Spring Boot 3/4 compatible \webmvc\ error attributes, and the \Order\ model was converted to a proper domain entity with MongoDB annotations.

The food-ordering-service has removed a large number of Java classes related to the previous implementation, including the OrderAggregate, Order model, OrderItem model, and associated controllers, repositories, and services for customers, restaurants, and dishes. This cleanup removes the old JPA-based persistence layer and command handlers, likely as part of a migration to a new architecture (such as event sourcing or a different data store), as indicated by the deletion of files like OrderAggregate.java, OrderController.java, and various service/DTO classes.

The customer-service module has had its customer management capabilities removed. This includes the deletion of the Customer model, repository, mapper, controller, DTOs, and service interfaces, along with associated events and queries. As a result, the API endpoints for creating, updating, deleting, and retrieving customers are no longer available in this service.

The project's Maven wrapper has been upgraded from version 0.5.6 to 3.3.4, and the underlying Maven distribution has been updated from 3.6.3 to 3.9.16. This change modernizes the build tooling, ensuring that developers and CI systems use a consistent, up-to-date version of Maven for all builds, which may include performance improvements and bug fixes associated with the newer Maven and wrapper versions.

.mvn · high confidence

Added comprehensive test coverage for the food ordering service; Added comprehensive test suite for the customer service.

The project has been upgraded to Spring Boot 4.1.0 and Axon Framework 4.13.1, introducing significant changes to the build configuration and dependencies. A new shared module, \axon-event-commons\, has been added to the multi-module build, allowing services to share common event definitions. The parent project's group ID and artifact ID have been updated to \com.ivanfranchin/axon-springboot-websocket\, and the Java version target has been raised to 25. Individual services now depend on \axon-event-commons\ and include specific test dependencies for JPA, Thymeleaf, WebSocket, and Testcontainers (MySQL, MongoDB, PostgreSQL). Additionally, the root \pom.xml\ now enforces code formatting via the Spotless plugin, and services have replaced generic \spring-boot-starter-web\ with \spring-boot-starter-webmvc\ and \spring-boot-starter-websocket\.
