Beans

@Springfield(strategy=Strategy.JPA, entity=TargetBean.class) 선언으로 다음 3개의 Bean 이 등록 된다. 자동생성 하려는 Bean(Name)이 이미 존재한다면, @Springfield 는 Bean 을 따로 생성하지 않는다.

bean name bean type bean implement
"customBeanController"EntityController<TargetBean, CustomBean>com.u2ware.springfield.controller. EntityHandler
"customBeanValidator" EntityValidator<TargetBean, CustomBean> com.u2ware.springfield.sample.part3.step2. CustomBeanValidator
"customBeanService" EntityService<TargetBean, CustomBean> com.u2ware.springfield.sample.part3.step2. CustomBeanService
Note:
CustomBeanService 에서 주입받은 "targetBeanRepository" Bean 은 이전 예제에서 이미 등록되어 있다.

Validation Layer

Bean Name 규칙이 맞도록, EntityValidator 의 구현체를 작성하고 등록한다. EntityValidatorImpl 를 상속하여 구현이 가능하다.

com.u2ware.springfield.validator.EntityValidatorImpl

EntityValidatorImpl 은 JSR-303 Bean Validation 을 처리하는 Validator 컴퍼넌트이다

예제에서, 중복키 여부를 체크하여 에러를 reject 하는 방식이 사용되었는데, 이는 org.springframework.validation.Validator 의 구현방식과 동일하다.
