提取XML譜寫的Java

Question

類

我有被註釋爲XMLType的

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "fooClass", propOrder = { 
    "fooElement1", 
    "fooElement2" 
}) 
public class fooClass{ 
    @XmlElement(required = true) 
    protected String fooElement1; 

    @XmlElement(required = true) 
    protected String fooElement2; 

    ..... 

} 

我希望能夠提取XML表示的Java類（最好爲流，但字符串是OK以及）在Java中，沿線的東西：

fooClass foo = new fooClass() 
foo.setFooElement1("baba") 
foo.setFooElement2("abab") 

String xmlRep = DomSomething(foo) 

任何想法該怎麼辦？

謝謝！

喜歡的東西：

try { 
    JAXBContext jaxbContext = JAXBContext.newInstance(fooClass.class); 
    Marshaller jaxbMarshaller = jaxbContext.createMarshaller(); 

    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    PrintStream ps = new PrintStream(baos); 
    jaxbMarshaller.marshal(fooInstance, ps); 

    String result = new String(baos.toByteArray()); 

    ... 
} catch (JAXBException e) { 
    ... 
}
