java - 使用 ksoap2 解析 XML 响应属性时出错返回 ClassCastException

Question

我试图弄清楚如何转换 Web 服务消耗的响应，当将响应 envelope.bodyIn 转换为我的扩展类对象“BiometricConfigurationResponse”时，我收到此错误:

java.lang.ClassCastException:org.ksoap2.serialization.SoapObject 无法转换为 org.tempuri.BiometricConfigurationResponse

该服务响应良好，如果我不转换它，我就会得到正确的转储。有什么想法吗？

这就是我正在做的事情:

BiometricConfigurationResponse response= null;
SoapObject obj = new SoapObject (wsNameSpace, methodName);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.implicitTypes = true;
envelope.dotNet = true;
envelope.setOutputSoapObject(obj);
envelope.addMapping(wsNameSpace, "BiometricConfigurationResponse", new BiometricConfigurationResponse().getClass());

HttpTransportSE androidHttpTransport = new HttpTransportSE(wsURL);
androidHttpTransport.debug = true;

 try {
         String soapAction=wsNameSpace + methodName;
         androidHttpTransport.call(soapAction, envelope);
        System.out.println(androidHttpTransport.requestDump);

        response =  (BiometricConfigurationResponse)envelope.bodyIn;


    } 
    catch (Exception e) {

        e.printStackTrace();
    }

这是我的自定义类

经过几天的研究，我了解到 WSDL 自动生成的代码解析属性而不是属性。所以我所做的是:

首先，我从本网站中的 WSDL 生成 stub 代码:http://www.wsdl2code.com/pages/home.aspx

我的网络服务名称是“nutriment”，当您在 MainActivity 中调用它时，您必须执行以下操作:

        nutriment nws= new nutriment();
        BiometricConfigurationResponse respuesta = nws.GetBiometricConfiguration();

        Log.i(TAG, String.valueOf(respuesta.coderAlgorithm));
        Log.i(TAG, String.valueOf(respuesta.templateFormat));

但它在所有情况下都会响应 0，因为 WDSL stub 文件正在解析属性而不是属性，因此当您打开序列化生成的文件时，您将得到如下内容:

import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;
import java.util.Hashtable;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;

public class BiometricConfigurationResponse implements KvmSerializable {

    public int coderAlgorithm;
    public int templateFormat;


    public BiometricConfigurationResponse(){}

    public BiometricConfigurationResponse(SoapObject soapObject)
    {
        if (soapObject == null)
            return;
        if (soapObject.hasProperty("coderAlgorithm"))
        {
            Object obj = soapObject.getProperty("coderAlgorithm");
            if (obj != null && obj.getClass().equals(SoapObject.class)){
                SoapPrimitive j =(SoapPrimitive) obj;
                coderAlgorithm = Integer.parseInt(j.toString());
               }
           else if (obj!= null && obj instanceof Number){
                coderAlgorithm = (Integer) obj;
            }


        }

        if (soapObject.hasProperty("templateFormat"))
        {
            Object obj = soapObject.getProperty("templateFormat");
            if (obj != null && obj.getClass().equals(SoapPrimitive.class)){
                SoapPrimitive j =(SoapPrimitive) obj;
                templateFormat = Integer.parseInt(j.toString());
            }else if (obj!= null && obj instanceof Number){
                templateFormat = (Integer) obj;
            }

        }

    }
    @Override
    public Object getProperty(int arg0) {
        switch(arg0){
            case 0:
                return coderAlgorithm;
            case 1:
                return templateFormat;

        }
        return null;
    }

    @Override
    public int getPropertyCount() {
        return 15;
    }

    @Override
    public void getPropertyInfo(int index, @SuppressWarnings("rawtypes") Hashtable arg1, PropertyInfo info) {
        switch(index){
            case 0:
                info.type = PropertyInfo.INTEGER_CLASS;
                info.name = "coderAlgorithm";
                break;
            case 1:
                info.type = PropertyInfo.INTEGER_CLASS;
                info.name = "templateFormat";
                break;

    }

    @Override
    public void setProperty(int arg0, Object arg1) {
    }

    @Override
    public String getInnerText() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void setInnerText(String arg0) {
        // TODO Auto-generated method stub

    }

}

技巧是修改解析，而不是获取属性(例如):

if (soapObject.hasProperty("coderAlgorithm")){
     Object obj = soapObject.getProperty("coderAlgorithm");
     if (obj != null && obj.getClass().equals(SoapObject.class)){
        SoapPrimitive j =(SoapPrimitive) obj;
        coderAlgorithm = Integer.parseInt(j.toString());
     }
     else if (obj!= null && obj instanceof Number){
     coderAlgorithm = (Integer) obj;
    }
}

获取属性(例如):

if (soapObject.hasAttribute("coderAlgorithm")) {
    Object obj = soapObject.getAttribute("coderAlgorithm");
    if (obj != null && obj.getClass().equals(SoapObject.class)){
       SoapPrimitive j =(SoapPrimitive) obj;
       coderAlgorithm = Integer.parseInt(j.toString());
    }
    else if (obj!= null && obj instanceof Number){
       coderAlgorithm = (Integer) obj;
   }
   else if (obj!= null && obj instanceof String){
       coderAlgorithm = Integer.parseInt(obj.toString());
  }
}
