我正在构建一个调用多个后端服务（当前为 2 个）的代理服务。所有服务都具有相同的接口。下面的幻灯片虽然不是英文的，但显示了部署

图表

该接口是使用 wsdl.exe 从 WSDL 编译的。该接口显然包含所有 C# 属性

[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "4.0.30319.1")]
[System.Web.Services.WebServiceBindingAttribute(Name="ServizioSanitario", Namespace="http://innovazione-ict.unina.it/WSDLSanita")]
public interface IServizioSanitario {

    /// <remarks/>
    [System.Web.Services.WebMethodAttribute()]
    [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://innovazione-ict.unina.it/WSDLSanita/InserisciDocumento", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Bare)]
    [return: XmlElement("idDocumento", Namespace="http://innovazione-ict.unina.it/WSDLSanita", DataType="ID")]
    string InserisciDocumento([XmlElement(Namespace="http://innovazione-ict.unina.it/WSDLSanita")] Documento documento);

    /// <remarks/>
    [System.Web.Services.WebMethodAttribute()]
    [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://innovazione-ict.unina.it/WSDLSanita/OttieniListaDocumenti", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Bare)]
    [return: XmlArray("listaMetadati", Namespace="http://innovazione-ict.unina.it/WSDLSanita")]
    [return: XmlArrayItem("metadatiDocumento", IsNullable=false)]
    MetadatiDocumentoTrovato[] OttieniListaDocumenti([XmlElement(Namespace="http://innovazione-ict.unina.it/WSDLSanita")] string codiceFiscale);

    /// <remarks/>
    [System.Web.Services.WebMethodAttribute()]
    [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://innovazione-ict.unina.it/WSDLSanita/RecuperaDocumento", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Bare)]
    [return: XmlElement("documento", Namespace="http://innovazione-ict.unina.it/WSDLSanita")]
    Documento RecuperaDocumento([XmlElement(Namespace="http://innovazione-ict.unina.it/WSDLSanita", DataType="ID")] string idDocumento);
}

代理建立在 Spring.net 上，具有动态代理和骨架实例化。它由一个空的 webapp 组成，它公开了在另一个程序集中实现的 Web 服务。

代理通过自己的接口包含对其他服务的引用：

class Broker : IServizioSanitario
{
        public IServizioSanitario[] ServiziConcreti { private get; set; }
}

我想为代理调用的每个服务实例化动态代理。为此，我使用了 Spring.net 依赖注入片段：

    <object id="ServizioSanitarioNetProxy" type="Spring.Web.Services.WebServiceProxyFactory, Spring.Services">
        <property name="ServiceUri" value="http://localhost:2263/ServizioSanitario2.asmx"/>
        <property name="ServiceInterface" value="It.Unina.MasterICT.ServizioSanitarioReference.IServizioSanitario, ServizioSanitarioReference"/>
      </object>

  <object id="BrokerConcrete" type="It.Unina.MasterICT.ServizioSanitario.Broker.Broker, BrokerImpl">
    <property name="ServiziConcreti">
      <list>
        <ref object="ServizioSanitarioDummyProxy"/>
        <ref object="ServizioSanitarioNetProxy"/>
      </list>
    </property>
  </object>

当我尝试运行 webapp 时，出现以下错误

按照 Spring 教程，它们使用手工创建的接口，而不是从 wsdl.exe 编译的。在http://localhost:2263/ServizioSanitario2.asmx我有另一个项目，来自另一个解决方案，运行一个定义如下的 Web 服务：public class ServizioSanitario2 : System.Web.Services.WebService, IServizioSanitario其中IServizioSanitario再次来自 wsdl .exe 编译。

在我目前的作业中，重要的是清楚地显示接口的使用（= 相同的接口）以允许实现类的可互换性（我将基本上表明可以随时使用远程或本地对象更改提供程序）。

所以我想克服这个错误，而不必手工制作一个基本上是上面显示的没有属性的新界面。

可能吗？考虑到要在SOAP消息中交换的复杂数据类型，因此具有“清除属性”接口实际上并不可行，因为数据对象具有自己的 XML 序列化属性。

谢谢你。
