我有以下 JAXB 注释类（使用 XJC 生成）

@XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "ReplicateTransactionDataNotificationType", namespace = "http://esb.pkobp/adapter/calypso/tradekast/transaction", propOrder = {
        "operationContext",
        "transactionData"
    })
    public class ReplicateTransactionDataNotificationType
        implements Serializable
    {

        @XmlElement(name = "OperationContext", required = true)
        protected OperationContextType operationContext;
        @XmlElement(name = "TransactionData")
        protected TransactionDataType transactionData;

        public OperationContextType getOperationContext() {
            return operationContext;
        }

        public void setOperationContext(OperationContextType value) {
            this.operationContext = value;
        }

        public TransactionDataType getTransactionData() {
            return transactionData;
        }

        public void setTransactionData(TransactionDataType value) {
            this.transactionData = value;
        }

    }

当以下列方式解组时，一切正常：

JAXBContext ctx = JAXBContext.newInstance(ReplicateTransactionDataNotificationType.class);
    Unmarshaller unmarshaller =  ctx.createUnmarshaller();
    JAXBElement<ReplicateTransactionDataNotificationType> result;
    result = unmarshaller.unmarshal(new StreamSource(new ByteArrayInputStream(xmlString.getBytes())), ReplicateTransactionDataNotificationType.class);

当以下列方式解组它时，它会崩溃并出现异常

(ReplicateTransactionDataNotificationType)unmarshaller.unmarshal(new StringReader(xmlString));

例外：

有人可以解释这种奇怪的行为吗？

被解组的 XML 文件粘贴在下面：

您需要ObjectFactory在创建JAXBContext. ObjectFactory包含@XmlElementDecl包含根元素信息的注释。我建议JAXBContext在生成模型的包名称上创建。
