用于Android开的简易WebService访问框架

因为公司业务需要用Android端能访问WebService开发的服务器接口，在网上找了一些资料拼凑了一简易的网络框架，原理就是每条请求都在子线程上实现，得到响应后再把结果通过Handler消息机制发给主线程，所有的子线程都由线程池来管理，大致意思这就样了。

package com.example.webservice.webservicedemo;import android.os.Handler;import android.os.Message;import android.support.v4.util.SimpleArrayMap;import org.ksoap2.SoapEnvelope;import org.ksoap2.serialization.SoapObject;import org.ksoap2.serialization.SoapSerializationEnvelope;import org.ksoap2.transport.HttpTransportSE;import org.xmlpull.v1.XmlPullParserException;import java.io.IOException;import java.util.concurrent.ExecutorService;import java.util.concurrent.Executors;/** * WebService访问方式的工具类 */public class WebServiceUtils {    // 访问的服务器是否由dotNet开发    public static boolean isDotNet = false;    // 线程池的大小    private static int threadSize = 5;    // 创建一个可重用固定线程数的线程池，以共享的无界队列方式来运行这些线程    private static ExecutorService threadPool = Executors.newFixedThreadPool(threadSize);    // 连接响应标示    public static final int SUCCESS_FLAG = 0;    public static final int ERROR_FLAG = 1;    /**     * 调用WebService接口，此方法只访问过用Java写的服务器     *     * @param endPoint        WebService服务器地址     * @param nameSpace       命名空间     * @param methodName      WebService的调用方法名     * @param mapParams       WebService的参数集合，可以为null     * @param reponseCallBack 服务器响应接口     */    public static void call(final String endPoint,                            final String nameSpace,                            final String methodName,                            SimpleArrayMap<String, String> mapParams,                            final Response reponseCallBack) {        // 1.创建HttpTransportSE对象，传递WebService服务器地址        final HttpTransportSE transport = new HttpTransportSE(endPoint);        transport.debug = true;        // 2.创建SoapObject对象用于传递请求参数        final SoapObject request = new SoapObject(nameSpace, methodName);        // 2.1.添加参数也可以不传        if (mapParams != null) {            for (int index = 0; index < mapParams.size(); index++) {                String key = mapParams.keyAt(index);                String value = mapParams.get(key);                request.addProperty(key, value);            }        }        // 3.实例化SoapSerializationEnvelope，传入WebService的SOAP协议的版本号        final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);        envelope.dotNet = isDotNet; // 设置是否调用的是.Net开发的WebService        envelope.setOutputSoapObject(request);        // 4.用于子线程与主线程通信的Handler，网络请求成功时会在子线程发送一个消息，然后在主线程上接收        final Handler responseHandler = new Handler() {            @Override            public void handleMessage(Message msg) {                super.handleMessage(msg);                // 根据消息的arg1值判断调用哪个接口                if (msg.arg1 == SUCCESS_FLAG)                    reponseCallBack.onSuccess((SoapObject) msg.obj);                else                    reponseCallBack.onError((Exception) msg.obj);            }        };        // 5.提交一个子线程到线程池并在此线种内调用WebService        if (threadPool == null || threadPool.isShutdown())            threadPool = Executors.newFixedThreadPool(threadSize);        threadPool.submit(new Runnable() {            @Override            public void run() {                SoapObject result = null;                try {                    // 解决EOFException                    System.setProperty("http.keepAlive", "false");                    // 连接服务器                    transport.call(null, envelope);                    if (envelope.getResponse() != null) {                        // 获取服务器响应返回的SoapObject                        result = (SoapObject) envelope.bodyIn;                    }                } catch (IOException e) {                    // 当call方法的第一个参数为null时会有一定的概念抛IO异常                    // 因此需要需要捕捉此异常后用命名空间加方法名作为参数重新连接                    e.printStackTrace();                    try {                        transport.call(nameSpace + methodName, envelope);                        if (envelope.getResponse() != null) {                            // 获取服务器响应返回的SoapObject                            result = (SoapObject) envelope.bodyIn;                        }                    } catch (Exception e1) {                        // e1.printStackTrace();                        responseHandler.sendMessage(responseHandler.obtainMessage(0, ERROR_FLAG, 0, e1));                    }                } catch (XmlPullParserException e) {                    // e.printStackTrace();                    responseHandler.sendMessage(responseHandler.obtainMessage(0, ERROR_FLAG, 0, e));                } finally {                    // 将获取的消息利用Handler发送到主线程                    responseHandler.sendMessage(responseHandler.obtainMessage(0, SUCCESS_FLAG, 0, result));                }            }        });    }    /**     * 设置线程池的大小     *     * @param threadSize     */    public static void setThreadSize(int threadSize) {        WebServiceUtils.threadSize = threadSize;        threadPool.shutdownNow();        threadPool = Executors.newFixedThreadPool(WebServiceUtils.threadSize);    }    /**     * 服务器响应接口，在响应后需要回调此接口     */    public interface Response {        public void onSuccess(SoapObject result);        public void onError(Exception e);    }}

然后在程序中只需要按如下方式调用即可。

private void requestLogin(final String userName, final String password) {        // 参数集合        SimpleArrayMap mapParams = new SimpleArrayMap();        mapParams.put("userName", userName + "");        mapParams.put("password", MD5Test.encrypt(password + ""));        mapParams.put("autoKey", "");        final Dialog dlg = DialogUtils.showProgressDialog(this, "正在登录...");        WebServiceUtils.call(ServiceConstants.EP_CHJ_USER_SERVICE,                ServiceConstants.NP_CHJ, ServiceConstants.M_CHJ_USER_LOGIN, mapParams,                new WebServiceUtils.Response() {                    @Override                    public void onSuccess(SoapObject result) {                        LogUtil.i(result + "");                        processLogin(result, userName, password);                        dlg.dismiss();                    }                    @Override                    public void onError(Exception e) {                        e.printStackTrace();                        dlg.dismiss();                    }                });    }
