java - KSoap2 和 KvmSerialized - 如何发送复杂的对象，如 Stringarrays

Question

我想将一个复杂的对象从我的 Ksoap 客户端发送到我的 Web 服务。它是我的类别类别的一个对象。该代码基于本教程的示例:

http://seesharpgears.blogspot.de/2010/10/ksoap-android-web-service-tutorial-with.html

Web 服务正在运行，并且 WSDL 文件显示类别对象。但是，如果我将类别对象发送到我的肥皂网络服务，则会显示以下错误:

[ERROR] Exception occurred while trying to invoke service method getCategoryObject org.apache.axis2.AxisFault: Unknow type {http://ws.chathura.com}Category Logcat shows up the following: 06-12 11:08:57.576: W/System.err(777): SoapFault - faultcode: 'soapenv:Server' faultstring: 'Unknow type {http://ws.chathura.com}Category' faultactor: 'null' detail: org.kxml2.kdom.Node@4054a528

这是我在 Tomcat 7 上运行的 Java Web 服务:

package com.chathura.ws;

import java.util.Vector;



public class HelloWorldWS
{


 public Category getCategoryObject(Category obj)
 {
  Category C1 = new Category();


    C1.setCategoryId(1);
    C1.setDescription("server desc");
    C1.setName("server Name");


    System.out.println(obj.getCategoryId());

    return C1;
 }
}

这是我在 Web 服务器上的类别类:

package com.chathura.ws;

public class Category {
 private int CategoryId;
 private String Name;
 private String Description;
 /**
  * @return the categoryId
  */
 public int getCategoryId() {
  return CategoryId;
 }
 /**
  * @param categoryId the categoryId to set
  */
 public void setCategoryId(int categoryId) {
  CategoryId = categoryId;
 }
 /**
  * @return the name
  */
 public String getName() {
  return Name;
 }
 /**
  * @param name the name to set
  */
 public void setName(String name) {
  Name = name;
 }
 /**
  * @return the description
  */
 public String getDescription() {
  return Description;
 }
 /**
  * @param description the description to set
  */
 public void setDescription(String description) {
  Description = description;
 }

}

这是 WSDL 文件:

    This XML file does not appear to have any style information associated with it. The document tree is shown below.

这是我的 Android 测试应用程序:

            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
            /*
             * Create Category with Id to be passed as an argument

            objekt.setValue(C);

            Request.addProperty(objekt);

这是来自 Android 客户端的类别类:

package de.bachelor.marcel;

import java.util.Hashtable;

import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;

public class Category implements KvmSerializable 
{

 public int CategoryId;
 public String Description;
    public String Name;

    public Category(){}


    public Category(int categoryId, String description, String name) 
    {

        CategoryId = categoryId;
        Name = name;
        Description = description;
    }

 @Override
 public Object getProperty(int arg0) 
 {
  switch(arg0)
        {
        case 0:
            return CategoryId;
        case 1:
            return Description;
        case 2:
         return Name;
        }
  return null;
 }

 @Override
 public int getPropertyCount() 
 {
  return 3;
 }

 @Override
 public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) 
 {
  switch(arg0)
        {
        case 0:
            arg2.type = PropertyInfo.INTEGER_CLASS;
            arg2.name = "CategoryId";
            break;
        case 1:
            arg2.type = PropertyInfo.STRING_CLASS;
            arg2.name = "Description";
            break;
        case 2:
            arg2.type = PropertyInfo.STRING_CLASS;
            arg2.name = "Name";
            break;
        default:break;
        }

 }

 @Override
 public void setProperty(int arg0, Object arg1) 
 {
  switch(arg0)
        {
        case 0:
            CategoryId = Integer.parseInt(arg1.toString());
            break;
        case 1:
         Description = arg1.toString();
            break;
        case 2:
            Name = arg1.toString();
            break;
        default:
            break;
        }

 }

}

Answer 1

尝试使用

private static final String NAMESPACE = "http://ws.chathura.com/xsd";

在您的 Android Activity 中，并将 getter 和 setter 添加到客户端中的 Category 类中。
