Question

我试图从我无法控制的SOAP服务中提取数据。层次结构包含ProductOrder - ＆gt; ShipTo - ＆gt;每个shipto有一个或多个shipToes和一个或多个Items的项目。

他们的API使用类似SQL的查询语言。在尝试提取包括项目的数据时，我得到了如下所示的堆栈跟踪。如果我排除项目，我可以将ProductOrders与ShipTo对象一起拉出，但项目始终是一个空列表。

产品订单服务包含如下方法：

public List<ProductOrderObj> getProductOrders(final Date startDate, final Date endDate) {
final String query = String.format("SELECT siteId,orderId,transactionId,purchaseAmount,taxDeductibleValue,\n" +
                "shippingCharge,additionalDonation,discountAmount,discountCode,\n" +
                "creationDate,createdBy,modifyDate,lastChangeBy,storeId,payment,\n" +
                "purchaser,interactionSource,shipTo,\n" +
                "receiptNumber,shipTo.item FROM ProductOrder where creationDate > %s and creationDate < %s",
        convertDate(startDate), convertDate(endDate));

log.info("query is " + query);

final Session session = convioClient.startSession();
final ArrayList<ProductOrderObj> events = new ArrayList<>();
for (int page = 1; page < 100; page++) {
    final List<? extends RecordObj> items = convioClient.query(session, page, ConvioConfiguration.MAX_DOWNLOADS_PER_REQUEST, query);
    if (items.size() < ConvioConfiguration.MAX_DOWNLOADS_PER_REQUEST) {
        events.addAll((List<ProductOrderObj>) items);
        break;
    }
    events.addAll((List<ProductOrderObj>) items);
}
return events;

}

反过来调用有效执行此操作的convioService.query方法

  private List<? extends RecordObj> queryInternal(final Session session, final 
               int page, final int pageSize, final String q) {
    // setup query
    final Query query = new Query();
    query.setPage(BigInteger.valueOf(page));
    query.setPageSize(BigInteger.valueOf(pageSize));
    query.setQueryString(q);
    log.trace(q);

    // perform query
    try {
        final Object obj = getWebServiceTemplate().marshalSendAndReceive(query,
                new SoapActionExecutionIdCallback(session));
        final QueryResponse response = (QueryResponse) obj;

        if (response != null) {
            log.debug("Response was a " + response.getClass().getName());
            return response.getRecord();
        }
    } catch (final Exception e) {
        log.error(e.getMessage());
        throw e;
    }

    throw new NullPointerException("response was null");
}

似乎有两个问题导致这种情况无效：

子对象的错误字段定义。 shipTo.items vs shipTo.Items
禁用marshaller / unmarshaller中的dtd验证

如何使用Spring WS和JAXB
