java - 从 XMLType 标记的 Java 类中提取 XML

Question

我有一个 Java 类，它被注释为 XMLType

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

    @XmlElement(required = true)
    protected String fooElement2;

    .....

}

我希望能够在 Java 中提取 XML 表示(最好是流，但字符串也可以)，大致如下:

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

String xmlRep = DomSomething(foo)

知道该怎么做吗？

谢谢!

类似于:

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) {
    ...
}
