java - 如何读取 xs :any response using CXF Generated Client?

Question

使用 CXF 2.1.4(生成的客户端)使用 Web 服务时，我在获取基于 WSDL 中以下 XSD 片段的响应时遇到问题。 CXF 生成一个表示它的列表，但是当我执行该服务时，响应为空。我将 wireshark 用于我正在接收的内容，确实响应 XMl 如预期的那样出现，但 CXF 只给我空对象。公开的服务是使用 .NET 实现的。

在响应对象的 XSD 下方。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

List由 getContent() 返回可能包含各种 org.w3c.dom.Element , JAXBElement ，或完全绑定(bind)的类。

如果 JAXB 上下文无法识别 <Siif>元素，那么 JAXB 将谨慎行事并使用单个 Element 填充列表表示 <Siif> 的对象和它的 child 。如果它确实识别它们，它将包含 JAXBElement which in turn contains a西夫 object, or it may contain the直接 Siif` 对象。

Java 无法在其类型中表达这种多样性，因此只需绑定(bind)到 List<Object> .
