Apache BeanUtilsBean 의 copy Properties 를 이용 하여 대상 속성 값 copy

http://redcoatjk.iteye.com/blog/1984967
개발 중 값 대상 과 실체 간 의 데이터 복 제 를 진행 합 니 다.
아파 치 BeanUtils Bean 의 copy Properties.
 
테스트 는 다음 과 같 습 니 다:

달성 효과:
student 의 속성 값 복사 완료, BeanUtil 간단 한 패키지 방법 (원래 방법 은 복사 할 때 java. util. Date 와 java. sql. Date 가 비어 있 을 때 오류 가 발생 합 니 다.) 패 키 징 후 util. Date 또는 sql. Date 에 직접 값 을 null 로 할당 합 니 다 (등록 기 를 바 꾸 어 구현)
