[Spring 3.0] O/X Mappers with JAXB

집에 도착하여 굶주린 하이에나 처럼 웹 서핑을 하다가 Spring 3.0 과 JAXB 를 연동할 수 있는 것을 보았습니다.

그 이름은 바로 Spring OXM...


자세한 내용을 확인할 시간이 없어서 그냥 바로 예제 프로젝트를 생성해보았습니다.


간단한 dtd 를 만들어서 >>>

[JAXB] DTD -> JAXB Model

<<< 글을 참조하여 model 객체를 생성하고


Toby님

의 글을 참조하여 pom.xml 을 구성하였습니다.



프로젝트 구성은 아래처럼 되었네요

코드 살짝 살펴보기...

printXML() 메소드 테스트 결과

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<Body>

<Image name="simple_image" id="image_0">

<Layout height="100px" width="100px" y="20px" x="20px"/>

</Image>

</Body>

그냥 살짝 테스트 해본 것이라 될지 안될지 약간 의구심이 있었지만... 예상외로 빠른 시간내에 결과를 보아서 뿌듯합니다.

다른 기능이나 문제점이 없는지도 살펴보아야 할 것 같네요...
