CXF java.lang.ClassCastException：com.sun.org.apache.xerces.internal.dom.ElementNSImpl无法强制转换为com.tibco.ur.schemas.getocr.Output

我在Maven中生成了类文件：

我用CXF调用Web服务：

final GenericWSService genericWSService = new GenericWSService();
final PortType portType = genericWSService.getPortTypeEndpoint();
...
final ResultList resultList = portType.operation(queryList);

返回的XML：

                            </ns1:Sales>

我可以通过这个回复，直到我进入xsd部分：

final List<ResultList.Result> results = resultList.getResult();

            for (final ResultList.Result result : results) {

                final ResultList.Result.Status status = result.getStatus();
                final int codeRetour = status.getReturn();
                final String message = status.getMessage();

                final List<Object> outputs = result.getOutput();

                for (final Object output : outputs) {

                    final Output outputOCR = (Output) output;

                    final List<Output.Store> stores = outputOCR.getStore();

最后一行抛出＆＃34; java.lang.ClassCastException＆＃34; （当然）：

java.lang.ClassCastException: com.sun.org.apache.xerces.internal.dom.ElementNSImpl cannot be cast to com.tibco.ur.schemas.getocr.Output

我尝试过很多东西（使用ElementNSImpl），但没有任何作用： - （

任何想法都会受到欢迎......

Answer 1

根据wsdl / top level架构，＆＃34;输出＆＃34; element是一个xsd：anyType。因此，JAXB会将其解组为DOM元素，除非有线上的信息说明它是什么类型。这基本上意味着xsi：type =＆＃34; tns：Output＆＃34;属性是必需的。

如果您知道它将成为输出，请更改wsdl中的模式以使Output元素为Output类型。 （我也会对输入做同样的事情）
