Medium Post: Chain of Responsibility in Spring Boot — Build an Order Validation Process

Chain of Responsibility in Spring Boot — Build an Order Validation Process What you’ll learn: - Validation as a pipeline: one OrderHandler per rule (fraud, stock, limit, etc.) - Spring-wired chain: List<OrderHandler> + @Order instead of manual setNext() - One endpoint: POST /api/orders/process runs through all checks in sequence - Fail-fast behavior: first failing handler sets status = REJECTED and stops the chain - Easy to extend: new rule = new handler class + @Order value For more details, check out the #Medium link below — this #article covers everything you need to know.
