java - jaxb 以字符串形式输出

Question

我想在字符串类型容器中获取生成的 xml 输出，并进一步希望在控制台中显示该字符串。

try {

            file = new File(XMLName);
            JAXBContext jaxbContext = JAXBContext
                    .newInstance(ActivityXmlV1.class);
            Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
            jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            jaxbMarshaller.marshal(activityXmlV1, file);
          //jaxbMarshaller.marshal(activityXmlV1, System.out);
            xmlData=asString(jaxbContext, activityXmlV1);
            System.out.println(xmlData);
            System.out.println("Sucess!!");
        } catch (UnmarshalException ue) {
        } catch (Exception e) {
    }

你可以做到这一点...

public String asString(JAXBContext pContext, Object pObject)throws JAXBException {
        java.io.StringWriter sw = new StringWriter();
        Marshaller marshaller = pContext.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
        marshaller.marshal(pObject, sw);
        return sw.toString();
    }

并在您想要执行的地方调用此方法:

System.out.println(asString(jaxbContext,activityXmlV1));
