이번에 소개할 방법은 Spring Framework에서 Jaxb-runtime, activation, Jaxb Api, JSTL을 활용하여 XML을 생성하는 방법에 대해서 소개하겠다.
JSP/Servlet 방식하고는 차이가 있는 점이 있다면, @(어노테이션)을 사용할 것이다.
* IDE: Eclipse 2020-06
* Library: Maven Project / Spring Framework 4.2.4 Releases.
1. https://mvnrepository.com/artifact/javax.servlet/servlet-api
javax.servlet 2.5
2. https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api
jaxb-api 2.3.0-b170201.1204
3. https://mvnrepository.com/artifact/javax.activation/activation
activation 1.1
4. https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-runtime
jaxb-runtime 2.3.0-b170127.1453
5. https://mvnrepository.com/artifact/javax.servlet/jstl

1. 프로젝트 구성도
실제로는 코드가 몇 줄 되지는 않지만, 문제는 라이브러리 셋팅 등에서 오류를 많이 경험할 수 있다.
그림 1. 프로젝트 구성도
2. Java Compiler, Build Path, Project Factes
* Java Compiler - compiler compliance level 1.8
* Build Path -> JRE System Library 1.8
* Project Factes - Java : 1.8
3. pom.xml
이 셋팅이 매우 무척 많이 중요하다.

7. 출력 결과
스프링에서 출력한 XML이다.
그림 2. 출력 결과
* 맺음글(Conclsuion)
스프링 프레임워크로 Jaxb2 외 다수 라이브러리를 활용하여 XML을 생성하였다.
