WebService

采用的免费webservice接口：

http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl

客户端代码如下：

package com.web.hh.constroller;import javax.xml.namespace.QName;import org.apache.axis2.AxisFault;import org.apache.axis2.addressing.EndpointReference;import org.apache.axis2.client.Options;import org.apache.axis2.rpc.client.RPCServiceClient;import org.apache.axis2.transport.http.HTTPConstants;public class ClientWeatherRPC {    /*     * 第三种方式，RPC     */    public static void main(String[] args) throws AxisFault {        //使用RPC方式调用WebService                 RPCServiceClient serviceClient = new RPCServiceClient();            Options options = serviceClient.getOptions();    //        options.setExceptionToBeThrownOnSOAPFault(false);          options.setSoapVersionURI(org.apache.axiom.soap.SOAP12Constants.SOAP_ENVELOPE_NAMESPACE_URI);         options.setProperty(HTTPConstants.CHUNKED, "false");        //指定调用WebService的URL            EndpointReference targetEPR = new EndpointReference("http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl");            options.setTo(targetEPR);            options.setAction("http://WebXml.com.cn/getWeather");          //指定方法的参数值            Object[] opAddEntryArgs = new Object[] {"昌平",""};            //指定要调用的方法及WSDL文件的命名空间            QName opAddEntry = new QName("http://WebXml.com.cn/", "getWeather");            //调用法并输出该方法的返回值    //        System.out.println(serviceClient.invokeBlocking(opAddEntry, opAddEntryArgs));          Object[] result=serviceClient.invokeBlocking(opAddEntry, opAddEntryArgs, new Class[]{String.class});         for (Object object : result) {             System.out.println(object.toString());         }     }}
