For this, we will implement a `food-ordering` app that consists of three [`Spring Boot`](https://docs.spring.io/spring-boot/index.html) applications: `customer-service`, `restaurant-service`, and `food-ordering-service`. These services were implemented with [`CQRS`](https://martinfowler.com/bliki/CQRS.html) and [`Event Sourcing`](https://martinfowler.com/eaaDev/EventSourcing.html) in mind. To achieve this, we used the [`Axon Framework`](https://www.axoniq.io/products/axon-framework). The three services are connected to `axon-server`, which is the [`Event Store`](https://en.wikipedia.org/wiki/Event_store) and `Message Routing` solution used. 4 | 5 | ## Proof-of-Concepts & Articles 6 | 7 | On [ivangfr.github.io](https://ivangfr.github.io), I have compiled my Proof-of-Concepts (PoCs) and articles. You can easily search for the technology you are interested in by using the filter. Who knows, perhaps I have already implemented a PoC or written an article about what you are looking for. 8 | 9 | ## Project Diagram 10 | 11 | ![project-diagram](documentation/project-diagram.jpeg) 12 | 13 | ## Applications 14 | 15 | - ### customer-service 16 | 17 | `Spring Boot` application that exposes a REST API to manage `Customers`. It also has a UI implemented using `JavaScript`, `jQuery`, and `Semantic UI`. 18 | 19 | ![customer-service](documentation/customer-service.jpeg) 20 | 21 | `customer-service` was implemented using the `Axon Framework`. Every time a customer is added, updated, or deleted, the service emits the respective event, i.e., `CustomerAddedEvent`, `CustomerUpdatedEvent`, or `CustomerDeletedEvent`. 22 | 23 | `customer-service` uses `MySQL` to store customer data. Additionally, it listens to order events, collects the order information that it needs, and stores them in an order table present in its own database, so that it doesn't need to call another service to get this information. 24 | 25 | - ### restaurant-service 26 | 27 | `Spring Boot` application that exposes a REST API to manage `Restaurants`. It also has a UI implemented using `JavaScript`, `jQuery`, and `Semantic UI`. 28 | 29 | ![restaurant-service](documentation/restaurant-service.jpeg) 30 | 31 | `restaurant-service` was implemented using the `Axon Framework`. Every time a restaurant is added, updated, or deleted, the service emits the respective event, i.e., `RestaurantAddedEvent`, `RestaurantUpdatedEvent`, or `RestaurantDeletedEvent`. The same applies to the restaurant dishes, whose events are: `RestaurantDishAddedEvent`, `RestaurantDishUpdatedEvent`, or `RestaurantDishDeletedEvent`. 32 | 33 | `restaurant-service` uses `PostgreSQL` to store restaurant/dish data. Additionally, it listens to order events, collects the order information that it needs, and stores them in an order table present in its own database, so that it doesn't need to call another service to get this information. 34 | 35 | - ### food-ordering-service 36 | 37 | `Spring Boot` application that exposes a REST API to manage `Orders`. It has a UI implemented using `JavaScript`, `jQuery`, and `Semantic UI`. 38 | 39 | ![food-ordering-service](documentation/food-ordering-service.jpeg) 40 | 41 | `food-ordering-service` was implemented using the `Axon Framework`. Every time an order is created, the service emits the respective event, i.e., `OrderCreatedEvent`. 42 | 43 | `food-ordering-service` uses `MongoDB` to store order data. Additionally, it listens to customer and restaurant/dish events, collects the information that it needs, and stores them in a customer or restaurant/dish table present in its own database, so that it doesn't need to call another service to get this information. 44 | 45 | - ### axon-event-commons 46 | 47 | `Maven` project where all events mentioned above are defined. It generates a JAR file that is added as a dependency in the `pom.xml` of `customer-service`, `restaurant-service`, and `food-ordering-service`. 48 | 49 | ## Prerequisites 50 | 51 | - [`Java 17`](https://www.oracle.com/java/technologies/downloads/#java17) or higher; 52 | - A containerization tool (e.g., [`Docker`](https://www.docker.com), [`Podman`](https://podman.io), etc.) 53 | 54 | ## Start Environment 55 | 56 | - Open a terminal and inside the `axon-springboot-websocket` root folder run: 57 | ```bash 58 | docker compose up -d 59 | ``` 60 | 61 | - Wait for Docker containers to be up and running. To check it, run: 62 | ```bash 63 | docker ps -a 64 | ``` 65 | 66 | ## Running applications with Maven 67 | 68 | Inside the `axon-springboot-websocket` root folder, run the following commands in different terminals: 69 | 70 | - **axon-event-commons** 71 | ```bash 72 | ./mvnw clean install --projects axon-event-commons 73 | ``` 74 | 75 | - **customer-service** 76 | ```bash 77 | ./mvnw clean spring-boot:run --projects customer-service -Dspring-boot.run.jvmArguments="-Dserver.port=9080" 78 | ``` 79 | 80 | - **restaurant-service** 81 | ```bash 82 | ./mvnw clean spring-boot:run --projects restaurant-service -Dspring-boot.run.jvmArguments="-Dserver.port=9081" 83 | ``` 84 | 85 | - **food-ordering-service** 86 | ```bash 87 | ./mvnw clean spring-boot:run --projects food-ordering-service -Dspring-boot.run.jvmArguments="-Dserver.port=9082" 88 | ``` 89 | 90 | ## Running applications as Docker containers 91 | 92 | - ### Build Docker images 93 | 94 | - In a terminal, make sure you are in the `axon-springboot-websocket` root folder; 95 | - Run the following script to build the Docker images: 96 | ```bash 97 | ./build-docker-images.sh 98 | ``` 99 | 100 | - ### Environment Variables 101 | 102 | - **customer-service** 103 | 104 | | Environment Variable | Description | 105 | |----------------------|-----------------------------------------------------------------------| 106 | | `MYSQL_HOST` | Specify the host of the `MySQL` database to use (default `localhost`) | 107 | | `MYSQL_PORT` | Specify the port of the `MySQL` database to use (default `3306`) | 108 | | `AXON_SERVER_HOST` | Specify the host of the `Axon Server` to use (default `localhost`) | 109 | | `AXON_SERVER_PORT` | Specify the port of the `Axon Server` to use (default `8124`) | 110 | 111 | - **restaurant-service** 112 | 113 | | Environment Variable | Description | 114 | |----------------------|--------------------------------------------------------------------------| 115 | | `POSTGRES_HOST` | Specify the host of the `Postgres` database to use (default `localhost`) | 116 | | `POSTGRES_PORT` | Specify the port of the `Postgres` database to use (default `5432`) | 117 | | `AXON_SERVER_HOST` | Specify the host of the `Axon Server` to use (default `localhost`) | 118 | | `AXON_SERVER_PORT` | Specify the port of the `Axon Server` to use (default `8124`) | 119 | 120 | - **food-ordering-service** 121 | 122 | | Environment Variable | Description | 123 | |----------------------|-----------------------------------------------------------------------| 124 | | `MONGODB_HOST` | Specify the host of the `Mongo` database to use (default `localhost`) | 125 | | `MONGODB_PORT` | Specify the port of the `Mongo` database to use (default `27017`) | 126 | | `AXON_SERVER_HOST` | Specify the host of the `Axon Server` to use (default `localhost`) | 127 | | `AXON_SERVER_PORT` | Specify the port of the `Axon Server` to use (default `8124`) | 128 | 129 | - ### Start Docker containers 130 | 131 | - In a terminal, make sure you are inside the `axon-springboot-websocket` root folder; 132 | - Run the following command: 133 | ```bash 134 | ./start-apps.sh 135 | ``` 136 | 137 | ## Application URLs 138 | 139 | | Application | URL | Swagger | 140 | |-----------------------|-----------------------|---------------------------------------| 141 | | customer-service | http://localhost:9080 | http://localhost:9080/swagger-ui.html | 142 | | restaurant-service | http://localhost:9081 | http://localhost:9081/swagger-ui.html | 143 | | food-ordering-service | http://localhost:9082 | http://localhost:9082/swagger-ui.html | 144 | 145 | ## Demo 146 | 147 | The GIF below shows a user creating a customer in the `customer-service` UI. Then, in the `restaurant-service` UI, they create a restaurant and add a dish. Finally, using the `food-ordering-service` UI, they submit an order using the customer and restaurant/dish created. Note that as soon as a customer or restaurant/dish is created, an event is sent, and the consumer of this event updates its UI in real-time using WebSockets. 148 | 149 | ![demo](documentation/demo.gif) 150 | 151 | ## Useful Commands & Links 152 | 153 | - **Axon Server** 154 | 155 | The `Axon Server` dashboard can be accessed at http://localhost:8024 156 | 157 | ![axon-server](documentation/axon-server.jpeg) 158 | 159 | - **MySQL** 160 | ```bash 161 | docker exec -it -e MYSQL_PWD=secret mysql mysql -uroot --database customerdb 162 | 163 | SELECT * FROM customers;
