All database calls to SalesOrderRepository should be restricted to the OrderService class.
Currently, there are instances where SalesOrderRepository is being accessed directly from other classes.
This issue manifests as a violation of the service layer architecture, leading to potential issues with maintainability and separation of concerns.
The problem occurs whenever SalesOrderRepository is accessed outside of OrderService.
No specific error messages may be observed, but this incorrect behavior can lead to tightly coupled code and difficulties in managing database interactions.
Solution Plan:
I reviewed multiple solutions and picked the following solution.
Identify all instances where ModifyFulfillmentService is directly accessing SalesOrderRepository:
Search for all occurrences of SalesOrderRepository in ModifyFulfillmentService.java.
Refactor ModifyFulfillmentService to use OrderService for database operations:
Replace all instances of SalesOrderRepository with OrderService in ModifyFulfillmentService.java.
Ensure OrderService has methods that encapsulate the required database operations.
Update unit tests for ModifyFulfillmentService:
Modify existing unit tests in ModifyFulfillmentServiceTest.java to mock OrderService instead of SalesOrderRepository.
Ensure tests cover the new method calls to OrderService.
Ensure OrderService provides necessary methods:
Add any missing methods in OrderService.java that were previously handled directly by SalesOrderRepository in ModifyFulfillmentService.
Run integration tests:
Execute all integration tests to ensure no new issues are introduced.
Here is why I selected the above solution:
This solution requires minimal code changes and maintains low complexity. It aligns with existing project conventions and patterns, ensuring project compatibility. The solution effectively addresses the problem by enforcing the service layer architecture and maintaining backward compatibility.
