1. jaxb marshall without @XmlRootElement
针对没有@XmlRootElement的情况如何marshall
Marshaller marshaller = jc.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); marshaller.marshal(new JAXBElement<MyClass>(new QName("uri","local"), MyClass.class, myClassInstance), System.out);
marshall方法只要改变一下就OK了。

2.
JAXB marshals XML differently to OutputStream vs. StringWriter
marshal to String .
转成String .
Marshaller marshaller = jc.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); StringWriter sw = new StringWriter(); marshaller.marshal(new JAXBElement<MyClass>(new QName("uri","local"), MyClass.class, myClassInstance), sw);
3.
printing output from xml
// Instantiate transformer input Source xmlInput = new StreamSource(new StringReader( "<!-- Document comment --><aaa><bbb/><ccc/></aaa>")); StreamResult xmlOutput = new StreamResult(new StringWriter()); // Configure transformer Transformer transformer = TransformerFactory.newInstance() .newTransformer(); // An identity transformer transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "testing.dtd"); transformer.setOutputProperty(OutputKeys.INDENT, "yes"); transformer.transform(xmlInput, xmlOutput); System.out.println(xmlOutput.getWriter().toString());
