ddd-java

This project is a sample implementation of Domain-Driven Design (DDD) based on Evans's principles, using Spring Boot. It follows a three-layer model where the Infrastructure layer is treated as a cross-cutting concern.

• UI Layer: Handles public interactions and receives use case requests (implemented via RESTful endpoints).
• Application Layer: Processes use cases and manages access to external resources.
• Domain Layer: Contains pure domain logic and does not depend on external resources.
• Infrastructure Layer: Manages the DI container, ORM, and various libraries.

To run the application in a containerized environment, ensure you have Docker and the VSCode DevContainer extension installed.

1. Navigate to the cloned ddd-java directory.
2. Run code . to open the directory in VSCode.
3. Select Open Container when prompted.
4. Open the Run And Debug view in VSCode.
5. Choose Run ddd-java.
6. Once the console displays Started Application, the server is running on port 8080.
7. Verify the status by running: curl http://localhost:8080/actuator/health

To run the application locally from a terminal, ensure you have JDK 21 or higher installed.

1. Navigate to the cloned ddd-java directory.
2. Execute the following command: ./gradlew bootRun --args='--spring.profiles.active=dev'
3. Once the console shows Started Application, the server is running on port 8080.
4. Verify the status by running: curl http://localhost:8080/actuator/health

The system includes batch jobs for processing business days and cash flows. Execute these in the appropriate business sequence.

# Close withdrawal requests
curl -X POST http://localhost:8080/system/job/daily/closingCashOut

# Advance the business day to the next day
curl -X POST http://localhost:8080/system/job/daily/processDay

# Realize cash flow (Reflects to the balance on the delivery date)
curl -X POST http://localhost:8080/system/job/daily/realizeCashflow

Once the server is running on port 8080, you can interact with the RESTful endpoints to test customer and administrative functionality.

# Request a withdrawal
curl -X POST -H "Content-Type: application/json" -d '{"accountId"  : "sample" , "currency" : "JPY", "absAmount": 1000}' http://localhost:8080/asset/cio/withdraw

# Search for outstanding withdrawal requests
curl 'http://localhost:8080/asset/cio/unprocessedOut'

# Search for deposit and withdrawal requests (Admin)
# Replace yyyy-MM-dd with actual dates
curl 'http://localhost:8080/admin/asset/cio?updFromDay=yyyy-MM-dd&updToDay=yyyy-MM-dd'
