How to marshall JAXBElement<Object> into org.w3c.dom.Element in Java using JAXB
提问by Constantine Gladky
I need to get Element object with request. I have ObjectFactory. I created an JAXBElement, and I need to marshall it to Element. Could anyone help me?
我需要通过请求获取 Element 对象。我有对象工厂。我创建了一个 JAXBElement，我需要将它编组到 Element。有人可以帮助我吗？
回答by Ian Roberts
You could marshal to a DOMResult:
你可以编组到一个DOMResult：
DOMResult res = new DOMResult();
marshaller.marshal(myJaxbElement, res);
Element elt = ((Document)res.getNode()).getDocumentElement();

In addition to Ian's answer, I suppose to first create a Document, as the unchecked cast can be omitted this way:
除了伊恩的回答，我想首先创建一个文档，因为可以通过这种方式省略未经检查的强制转换：
Document document =
DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
JAXB.marshal(jaxbElement, new DOMResult(document));
Element element = document.getDocumentElement();
