Java: Constructor vs Field Injection
Answer
It resolves dependencies before instantiating beans.
Spring Boot uses constructor injection to ensure all bean dependencies are available before creating an instance. This efficient dependency resolution is crucial for large applications where beans like OrderService need multiple dependencies such as PaymentService and InventoryService.
