java - 意外元素(uri :""，本地 :"")。预期元素是(无)

Question

我无法使用 cxf-xjc-plugin 将响应 xml 映射到由 xsd 生成的 java。

pom.xml

        StringReader reader = new StringReader(xml);

        Unmarshaller jaxbUnmarshaller2 = jaxbContext2.createUnmarshaller();
        AutomatedIDResponse obj = (AutomatedIDResponse) jaxbUnmarshaller2.unmarshal(reader);
        }catch (JAXBException e) {
            System.out.println("JAXBException" + e);
        }
    }

错误:

JAXBExceptionjavax.xml.bind.UnmarshalException: unexpected element (uri:"urn:automatedIDgenerationResponse", local:"automatedIDgenerationResponse"). Expected elements are (none)

我可以通过这种方式将 xml 转换为对象:

public static AutomatedIDResponse xmlToObject(String xmlString) throws XMLStreamException, UnsupportedEncodingException, JAXBException{
        InputStream stream = new ByteArrayInputStream(xmlString.getBytes("UTF-8"));
        JAXBContext jaxbContext2 = JAXBContext.newInstance(AutomatedIDResponse.class);
        Unmarshaller jaxbUnmarshaller2 = jaxbContext2.createUnmarshaller();
        XMLInputFactory factory = XMLInputFactory.newInstance();
        XMLEventReader someSource = factory.createXMLEventReader(stream);
        JAXBElement<AutomatedIDResponse> userElement = jaxbUnmarshaller2.unmarshal(someSource, AutomatedIDResponse.class);
        AutomatedIDResponse responseObject = userElement.getValue();
        return responseObject;
    }
