템플릿 방법의 응용

얼마 전에 Edison Zhou가 쓴 글을 읽었습니다.https://www.cnblogs.com/edisonchou/p/7260758.html;
그래서 자신의 업무에서 LogicHandler의 OrderLogicHandler 논리 처리 클래스에서 코드가 너무 길고 1000줄에 달하기 때문에 읽기가 불편하다고 생각했다.주로 증원 감원 주문서를 분리 처리하고 단일 처리의 절차가 똑같지만 각자의 내용이 다르기 때문에 코드를 읽는 데 편리하도록 코드 재정비를 하고 템플릿 방법 모델로 이를 정리했다.
처리 절차는 신고한 인원 자료를 검증하여 요구에 부합되는 주문을 받거나 생성 주문서를 보관하는 것이다.

템플릿 클래스: OrderApiHelper. 계승된 하위 클래스에서 모두 사용되는 공통된 방법은 부모 클래스에 쓸 수 있고, 형식은 보호된 것으로 성명해야 한다. 이런 종류는 OrderApiCutHelper에서 다시 쓰는 방법에서 직접 호출할 수 있다.HasPackage(), IsIninsurance() 등의 방법

구체적인 하위 클래스: OrderApiCutHelper, OrderApiAddHelper는 OrderApiHelper를 계승하여 각자의 검증과 주문 생성 방법을 다시 쓴다.
