无法将类型 <CLASSNAME> 编组为元素，因为它缺少 @XmlRootElement 注释

Question

不是重复的因为我已经尝试了很多来自stackoverflow的解决方案，比如添加

@XmlRootElement(name="Generic")

并且还尝试将请求和响应对象包装在

javax.xml.bind.JAXBElement

中，但到目前为止对我没有任何作用。编组/解组一直失败，自从我调试和解决这个问题以来已经有 2 天了。

wsdl 文件很大，所以只在这里发布 WSDL 文件中的重要内容。

soap.wsdl

WSDL 的 Java 配置类：

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {


    @Bean
    public Jaxb2Marshaller jaxb2Marshaller() {
        Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
        jaxb2Marshaller.setContextPath("com.example.camel.client.stub");
        jaxb2Marshaller.setMarshallerProperties(new HashMap<>() {{
            put(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, true);
        }});
        return jaxb2Marshaller;
    }


    @Bean
    public Marshaller marshaller() {
        return jaxb2Marshaller().createMarshaller();
    }

    @Bean
    public Unmarshaller unmarshaller() {
       return jaxb2Marshaller().createUnmarshaller();
    }

    @Bean
    public SoapClient soapClient(Jaxb2Marshaller marshaller) {
        SoapClient client = new SoapClient();
        client.setDefaultUri("https://myenvtest.oraclecloud.com:443/idcws/GenericSoapPort");
        client.setMarshaller(marshaller);
        client.setUnmarshaller(marshaller);
        return client;
    }

下面是将调用 SOAP 服务的 SoapClient 类

SoapClient.java

public javax.xml.bind.JAXBElement<Generic> getGenericResponse() throws JAXBException {
        Generic request = new ObjectFactory().createGeneric();
        Service service = new ObjectFactory().createService();
        Service.Document document = new ObjectFactory().createServiceDocument();
        Field field = new ObjectFactory().createField();
        Container container = new ObjectFactory().createContainer();
        container.getField().add(field);
        service.setUser(container);
        field.setName("dID");
        field.setValue("2088250");
        document.getField().add(field);
        service.setIdcService("GET_FILE");
        service.setDocument(document);
        request.setService(service);
        request.setWebKey("cs");



       /* jakarta.xml.bind.Marshaller marshaller = jaxb2Marshaller.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
        marshaller.marshal(new JAXBElement<Generic>(new QName("http://www.oracle.com/UCM","GenericRequest"), Generic.class, request),
                System.out);

        String t = marshallXml(request);*/

        javax.xml.bind.JAXBElement<Generic> res = ( javax.xml.bind.JAXBElement<Generic>)
        getWebServiceTemplate().marshalSendAndReceive("https://myenvtest.oraclecloud.com/idcws/GenericSoapPort", request, new SoapActionCallback("https://myenvtest.oraclecloud.com/idcws/Generic"));
        
return null;
    }

我不断收到的错误是：

com.sun.istack.SAXException2: unable to marshal type "com.example.camel.client.stub.Generic" as an element because it is missing an @XmlRootElement annotation
