1. JAVA -> XML   (JAXB)
2. JAXB -> JSON  (Jersey)
3. JAVA -> XML   (XStream)
4. JAVA -> JSON  (XStream)

1. 맛보기
// Person.java public class Person {     private String userid;     private String username;     private String email;     private Date regdate;         public Person() {         this.userid = "alseom";         this.username = "알썸";         this.email = "alseom@alseom.co.kr";         this.regdate = new Date();     } } // Main.java public class Main {     public static void main(String[] args) {         XStream xStream = new XStream(new DomDriver());         xStream.alias("PERSON", Person.class);         xStream.toXML(new Person());     } }
<PERSON>     <userid>alseom</userid>     <username>알썸</username>     <email>alseom@alseom.co.kr</email>     <regdate>2009-11-26 17:38:26.843 KST</regdate> </PERSON>

2. Annotations 이용
// Person.java @XStreamAlias("PERSON") public class Person {     @XStreamAlias("ID")     @XStreamAsAttribute     private String userid;     @XStreamAlias("NAME")     private String username;     private String email;     @XStreamAlias("DATE")     private Date regdate;         @XStreamImplicit(itemFieldName="DATA")     private List<String> list;         public Person() {         this.userid = "alseom";         this.username = "알썸";         this.email = "alseom@alseom.co.kr";         this.regdate = new Date();           list = new ArrayList<String>();         list.add("키보드");         list.add("마우스");         list.add("노트북");     } } // Main.java public class Test {     public static void main(String[] args) {         XStream xStream = new XStream();         xStream.autodetectAnnotations(true);         xStream.toXML(new Person());     } }
<PERSON ID="alseom">     <NAME>알썸</NAME>     <email>alseom@alseom.co.kr</email>     <DATE>2009-11-27 09:17:36.734 KST</DATE>     <DATA>키보드</DATA>     <DATA>마우스</DATA>     <DATA>노트북</DATA> </PERSON>
기타 나머지 Anotations 은 [여기] 를 참고하자.. 아~ 구찮어. ㅋ
JAXB의 Anotations 개념과 비슷해서 이해하기 어렵지 않다.
