我正在尝试修改和发送复杂的对象到我的网络服务/从我的网络服务，但我的问题是，我只能接收或发送，没有任何例外。

代码基于本教程的示例

这是我在 Tomcat7 上运行的 Java Webservice：

public class HelloWorldWS
{   
    public Category GetSumOfTwoInts(Category C )
    {
        Category back= new Category();
        back.setCategoryId(112);
        back.setDescription("server");
        back.setName("myNameFromServer");

        System.out.println("For testing only: " + C.getCategoryId() + C.getDescription());

        return back;
    }
}

这是生成的 WSDL 文件：

这是我的 Android 应用程序：

public class WSClientActivity extends Activity {

    private TextView tv;
    private Button bt;
    private EditText et;

    private static final String SOAP_ACTION = "http://WS.androidroleplay.fk4.de.hs_bremen.de/GetSumOfTwoInts";
    private static final String METHOD_NAME = "GetSumOfTwoInts";
    private static final String NAMESPACE = "http://WS.androidroleplay.fk4.de.hs_bremen.de";
    private static final String NAMESPACE2 = "http://WS.androidroleplay.fk4.de.hs_bremen.de/xsd";
    private static final String URL = "http://192.168.178.28:8080/WebProject_DB16/services/HelloWorldWS?wsdl";
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
        /*
         * Create Category with Id to be passed as an argument
         * 
         * */
        Category C = new Category();
        C.setCategoryId(1);
        C.setDescription("Client Desc");
        C.setName("Client Name"); 

        /*
         * Set the category to be the argument of the web service method
         * 
         * */

        PropertyInfo objekt = new PropertyInfo();
        objekt.setName("C");
        objekt.setValue(C);
        objekt.setType(C.getClass());
        objekt.setNamespace(NAMESPACE2);

        Request.addProperty(objekt);

        /*
         * Set the web service envelope
         * 
         * */
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        envelope.setOutputSoapObject(Request);

        envelope.addMapping(NAMESPACE2, "Category",new Category().getClass());

//        envelope.avoidExceptionForUnknownProperty=true;

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        /*
         * Call the web service and retrieve result ... how luvly <3
         * 
         * */
        try
        {
            List<HeaderProperty> headerList = new ArrayList<HeaderProperty>();
            headerList.add(new HeaderProperty("Authorization", "Basic " + org.kobjects.base64.Base64.encode("tomcat:tomcat".getBytes()))); // "username:password"

            androidHttpTransport.call(SOAP_ACTION, envelope, headerList);
            SoapObject response = (SoapObject)envelope.getResponse();
            C.setCategoryId(Integer.parseInt(response.getProperty(0).toString()));
            C.setName(response.getProperty(1).toString());
            C.setDescription(response.getProperty(2).toString());

            TextView tv = (TextView)findViewById(R.id.texthallo);
            tv.setText("CategoryId: " +C.getCategoryId() + " Name: " + C.getName() + " Description: " + C.getDescription()); //"CategoryId: " +C.getCategoryId() + " Name: " + C.getName() + " Description: " + C.getDescription()
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

如果我启动应用程序，我会得到这个异常：

W/System.err(783): java.lang.RuntimeException: Unknown Property: categoryId

如果我将其注释掉，我可以收到复杂的对象：

PropertyInfo objekt = new PropertyInfo();
        objekt.setName("C");
        objekt.setValue(C);
        objekt.setType(C.getClass());
        objekt.setNamespace(NAMESPACE2);

        Request.addProperty(objekt);

还有这个：

envelope.addMapping(NAMESPACE2, "Category",new Category().getClass());

**

或者

**

如果我将其注释掉，我可以发送复杂对象：

SoapObject response = (SoapObject)envelope.getResponse();
            C.setCategoryId(Integer.parseInt(response.getProperty(0).toString()));
            C.setName(response.getProperty(1).toString());
            C.setDescription(response.getProperty(2).toString());

但如果我想要两者，我会得到已经命名的异常。

我想问题可能是，我使用了两个不同的命名空间（NAMESPACE和NAMESPACE2），但如果我只使用NAMESPACE我的网络服务，就会出现这个异常：

[ERROR] Exception occurred while trying to invoke service method GetSumOfTwoInts
org.apache.axis2.AxisFault: Unknow type {http://WS.androidroleplay.fk4.de.hs_bremen.de}Category
    at org.apache.axis2.databinding.utils.BeanUtil.deserialize(BeanUtil.java:349)

或者如果我只使用 NAMESPACE2 我得到这个异常：

[ERROR] Exception occurred while trying to invoke service method GetSumOfTwoInts
org.apache.axis2.AxisFault: namespace mismatch require http://WS.androidroleplay.fk4.de.hs_bremen.de found http://WS.androidroleplay.fk4.de.hs_bremen.de/xsd

编辑：

如果我想发送一个复杂的对象并接收一个像 or 这样的“正常”对象，String或者int如果我发送一个正常的对象并接收一个复杂的对象，它就可以工作。

但是如果我想发送和修改一个复杂的对象，我会遇到麻烦...... :(

正如我之前评论过你的，

W/System.err(783): java.lang.RuntimeException: Unknown Property: categoryId

异常是因为您在 Category 类中的成员变量必须是小写的。

并尝试这个发送和接收复杂的对象：

    SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
    Category C = new Category();
    C.setCategoryId(1);
    C.setDescription("Client Desc");
    C.setName("Client Name"); 

    Request.addProperty(C.getClass().getSimpleName(), C);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(Request);
    envelope.addMapping(NAMESPACE2, C.getClass().getSimpleName(), C.getClass());

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    Category ans = null;
    try {
        androidHttpTransport.call(NAMESPACE + METHOD_NAME, envelope);
        ans = (Category)envelope.getResponse();
        tv.setText("CategoryId: " + ans.getCategoryId() + " Name: " + ans.getName() + " Description: " + ans.getDescription()); 
    }
    catch(Exception e) {
        e.printStackTrace();
    }

在我的情况下 SoapSerializationEnvelope类包含方法readSerializable (XmlPullParser parser, KvmSerializable obj)，有以下条件

.. name.equals(info.name) && parser.getNamespace().equals(info.namespace) ..

所以我检查了我的DataType的类，发现方法getPropertyInfo将不正确的命名空间放入了 Property。

所以属性的命名空间必须与解析器的命名空间相同。
