Beans

@Springfield(strategy=Strategy.JPA) 선언으로 다음 4개의 Bean 이 등록 된다. 자동생성 하려는 Bean(Name)이 이미 존재한다면, @Springfield 는 Bean 을 따로 생성하지 않는다.

bean name bean type bean implement
"targetBeanController"EntityController<TargetBean, TargetBean>com.u2ware.springfield.controller. EntityHandler
"targetBeanValidator" EntityValidator<TargetBean, TargetBean> com.u2ware.springfield.validation. EntityValidatorImpl

Service Layer

Bean Name 규칙이 맞도록, EntityService 의 구현체를 작성하고 등록한다. EntityServiceImpl 를 상속하여 구현이 가능하다.

com.u2ware.springfield.service.EntityServiceImpl

EntityServiceImpl 은 EntityRepository 를 주입 받아서 Repository 를 이용한 기본적인 CRUD 를 처리하는 Service 컴퍼넌트이다.

Validation Layer

com.u2ware.springfield.validation. RejectableException이 발생하면 EntityController 에서 이를 Validation results Object ( org.springframework.validation. BindingResult) 에 reject 한다.

Note
@Springfield 에서 Validation 처리는 두가지 방법을 적절히 이용할 수 있다.
  1. RejectableException 을 이용하여 서비스 레이어에서 예외를 던지는 방식. 주로 비즈니스 의존적인 검증 프로세스에 쓰인다.
  2. EntityValidator 에서 처리하는 방식. 예제
