JAXB 2.0을 이용한 Java-to-XML Schema
JAXB 1.x에서는 Schema-to-Java 만 지원되었었다. 여기서는 JAXB 2.0에서 추가된 Java-to-Schema에 관하여 살펴보도록 한다.
 

Sample Java Class

techtip.Scientist.java
package techtip;
 
import javax.xml.bind.annotation.*;
import java.util.Collection;
import techtip.Person;
 
@XmlRootElement
public class Scientist  {
   
    private Person person;   
    private String researchInstitute;
    private Collection publications;
           
    public Scientist() {       
    }
   
    public Scientist (Person p, String ri, Collection col) {
        person = p;
        researchInstitute = ri;
        publications = col;
       
    }
   
    public Person getPerson() {
       return person;     
    }
   
    public void setPerson (Person value) {
        person = value;
    }
   
    public String getresearchInstitute() {
        return researchInstitute;
    }
   
    public void setResearchInstitute(String institute) {       
        researchInstitute = institute;       
    }   
          
    public Collection getPublications() {
        return publications;
    }
   
    public void setPublications(Collection publish) {
        publications = publish;
    }
}
 
techtip.Person.java
package techtip;
 
import javax.xml.bind.annotation.*;
import techtip.*;
 
@XmlType      
public class Person  {
           
    private String name;
    private int age;
    private String sex;
  
    public Person() {      
    }
   
    public Person(String name, int age, String sex){
       
        this.name=name;
        this.age = age;
        this.sex = sex;               
    }
   
    public String getName() {
        return name;
    }
   
    public void setName(String value) {       
        name = value;
    }
   
    public int getAge() {
        return age;
    }
   
    public void setAge(int value) {       
        age = value;
    }
   
    public String getSex() {
        return sex;
    }
   
    public void setSex(String value) {       
        sex = value;
    }   
}
 
@XmlRootElement : 해당 클래스는 Top 레벨 클래스임을 의미하는 Annotation
@Xmltype : 해당 클래스가 구조체임을 의미하는 Annotation
 

XmlSchema Generate

C:jaxbtechtipclasses>set path=%path%;C:jwsdp-2.0jaxbbin;
 
C:jaxbtechtipclasses>schemagen
Usage: schemagen [-options ...] <java files>
Options:
    -d <path>         :  specify where to place processor and javac generated class files
    -cp <path>        :  specify where to find user specified files
    -classpath <path> :  specify where to find user specified files
    -version          :  display version information
 
C:jaxbtechtipclasses>schemagen techtip.Scientist
Note: Writing schema1.xsd
