FoodFast

Version française

FoodFast is a Java prototype of a meal delivery platform developed as part of a component-oriented programming project.

The project combines several standard backend concerns:

• object-oriented modeling of business entities
• application logic around orders
• collection-based search operations in Java
• error handling with a custom exception
• concurrency with ExecutorService and ConcurrentHashMap
• PostgreSQL persistence through JDBC and PreparedStatement

Features

• create customers, dishes, and orders
• compute the total price of an order
• manage the lifecycle of an order with OrderStatus
• add orders to a delivery platform
• search by identifier, customer, or status
• simulate restaurant preparation with a possible failure
• basic logging through a singleton logger
• store orders in PostgreSQL

Technologies

• Java
• Maven
• JUnit 5
• PostgreSQL
• Docker Compose

Start the Database

docker-compose up -d

The local PostgreSQL database is initialized automatically with the schema defined in db/init.sql.

Inspect the Database

To check the orders stored in the database:

docker exec -it foodfast-db psql -U postgres -d foodfast -c "SELECT * FROM orders;"

Build and Run

mvn clean package
mvn exec:java -Dexec.mainClass=Application

Run the Tests

mvn test

Database Connection Variables

The project uses the following defaults:

• FOODFAST_DB_URL=jdbc:postgresql://localhost:5432/foodfast
• FOODFAST_DB_USER=postgres
• FOODFAST_DB_PASS=postgres
