如果对WebService一无所知的话,建议先看看这两篇博客,对你WebService很有帮助。

本人也是菜鸟一名,WebService已经是很老的技术了,但现在仍有使用,刚开始接触的时候,是无从入手呀,看了上面几篇文章以后,渐渐的会使用了,这里感谢网上开源的作者和文章,网上基本没有封装的,这里通过这个项目下来,学会了封装,虽然不难,但对于我这种刚出道的菜鸟来说,还是很不容易的,这里记录下来,希望也能帮助到其他的同行。实践才是检验真理的唯一标准,全部代码如下,有注释:

package com.example.applicationicon;

import java.io.IOException;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpResponseException;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;
import android.os.Handler;
import android.os.Message;

public class WebServiceUtils {
public static final String WEB_SERVER_URL = "";
// 含有3个线程的线程池
private static final ExecutorService executorService = Executors
.newFixedThreadPool(3);
// 命名空间
private static final String NAMESPACE = "";


/**

*/
public static void callWebService(String url, final String methodName,
HashMap<String, String> properties,
final WebServiceCallBack webServiceCallBack) {
// 创建HttpTransportSE对象,传递WebService服务器地址
final HttpTransportSE httpTransportSE = new HttpTransportSE(url);
// 创建SoapObject对象
SoapObject soapObject = new SoapObject(NAMESPACE, methodName);

// SoapObject添加参数

//写真实的变量名也没有用,传递参数必须是arg开头,必须是arg0 ,arg1 一直拍下去

if (properties != null) {
for (Iterator<Map.Entry<String, String>> it = properties.entrySet()
.iterator(); it.hasNext();) {
Map.Entry<String, String> entry = it.next();
soapObject.addProperty(entry.getKey(), entry.getValue());
}
}
// 实例化SoapSerializationEnvelope,传入WebService的SOAP协议的版本号 

//tomcat 7.055 for 64  jdk 1.6 for 64  web3.0 这里写 ver12 ,如果是ver11会报 http 415错误
final SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
SoapEnvelope.VER12);
// 设置是否调用的是.Net开发的WebService
soapEnvelope.bodyOut = soapObject;
soapEnvelope.dotNet = false;//如果调用的是.Net的WebService,这里为true,否则为false,不然调用会不成功
soapEnvelope.setOutputSoapObject(soapObject);
httpTransportSE.debug = true;
// 用于子线程与主线程通信的Handler
final Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
// 将返回值回调到callBack的参数中
webServiceCallBack.callBack((Object) msg.obj);
}
};

// 开启线程去访问WebService
executorService.submit(new Runnable() {
@Override
public void run() {
Object resultSoapObject = null;
try {
httpTransportSE.call(WEB_SERVER_URL + methodName, soapEnvelope);
if (soapEnvelope.getResponse() != null) {
// 获取服务器响应返回的SoapObject
resultSoapObject = (Object) soapEnvelope.bodyOut;
}
} catch (HttpResponseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
} finally {
// 将获取的消息利用Handler发送到主线程
mHandler.sendMessage(mHandler.obtainMessage(0,
resultSoapObject));
}
}
});
}
