如何使用CXF生成的客户端读取xs:any response？

Question

在使用CXF 2.1.4 (生成的客户端)使用webserice时，根据WSDL中的以下XSD片段获取响应时遇到问题。CXF生成一个表示它的列表，但是当我执行该服务时，响应为null。我使用wireshark来处理我所收到的内容，实际上，响应XMl如期而至，但CXF只给了我空对象。公开的服务是使用.NET实现的。

在响应对象的XSD下面。和

    <!--- chunk -->
     <s:element name="GestionSIIFResponse">
    <s:complexType>
      <s:sequence>
        <s:element minOccurs="0" maxOccurs="1" name="GestionSIIFResult">
          <s:complexType mixed="true">
            <s:sequence>
              <s:any />
            </s:sequence>
          </s:complexType>
        </s:element>
      </s:sequence>
    </s:complexType>
  </s:element>
  <!--- chunk -->

这是我从服务中得到的响应：

   <soap:Body>
  <GestionSIIFResponse xmlns="http://tempuri.org/">
     <GestionSIIFResult>
        <Siif xmlns="">
           <Pagina>NUY001B</Pagina>
           <Exitos>
              <ExitoRep>
                 <CodExito>SIL0082</CodExito>
                 <DesExito>La transaccion se ha aplicado satisfactoriamente</DesExito>
              </ExitoRep>
           </Exitos>
           <InformacionCab/>
           <Repeticiones/>
        </Siif>
     </GestionSIIFResult>
  </GestionSIIFResponse>

​

下面是生成的java类，它应该“保存”来自web服务的响应。

Answer 1

getContent()返回的List可能包含各种org.w3c.dom.Element、JAXBElement或完全绑定的类。

如果JAXB上下文不能识别<Siif>元素，那么JAXB将采取安全措施，并使用表示<Siif>及其子元素的单个Element对象填充列表。如果它能够识别它们，它将直接包含JAXBElementwhich in turn contains aSiifobject, or it may contain theSiif`对象。

Java不能在它的类型中表达这种变化，所以只绑定到List<Object>。
