public class JAXBDemo {public static void main(String[] args) {// 创建xml文档对象，其保存在E盘的根目录下的test.xml文件File xmlFile = new File("E:\\test.xml");//声明JAXBContext上下文对象JAXBContext context;try {//通过指定映射的类创建上下文context = JAXBContext.newInstance(Article.class);//通过上下文创建java转化xml的对象Marshaller//Marshaller m = context.createMarshaller();////创建xml中的数据//Article article = new Article();//article.setAuthor("Janet");//article.setDate("20080801");//article.setEmail("janetvsfei@yahoo.com.cn");//article.setTitle("XML");////将java对象转化到xml//m.marshal(article, xmlFile);//通过上下文创建xml转化java的对象UnmarshallerUnmarshaller u = context.createUnmarshaller();Article article = (Article)u.unmarshal(xmlFile);System.out.println(article.getAuthor());System.out.println(article.getDate());System.out.println(article.getEmail());System.out.println(article.getTitle());} catch (JAXBException e) {e.printStackTrace();}}}
