axis2 tutorial--2种方法实现调用webservice

天气预报：

endpoint:  http://www.webxml.com.cn/WebServices/WeatherWebService.asmx

wsdl:          http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl


方法1：用axis2\bin\wsdl2java生成stub。

1、到http://ws.apache.org/axis2下载axis-binary.zip

2、设置Axis2的Home环境:

变量名：AXIS2_HOME

值：D:\axis2\axis2-1.4.1-bin\axis2-1.4.1 就是你下下来的安装目录。

3、进入命令行：出入 %AXIS2_HOME%\bin\wsdl2java -uri http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl -p cn.com.webxml -s -o stub

参数:uri ---你要生成JAVA代码需要的wsdl文件，可以是网上的，也可以是本地的。

      -p  生成出的stub的包的生命    -o创建出的文件夹名。

完成后会在相对应的目录生成该JAVA文件，目录结构就是stub/src/cn.com.webxml

4、把该JAVA文件导入到ECLIPSE,注意eclipse的java project的buildpath加入%AXIS2_HOME%/lib下所有的JAR。不然会编译出错。

5、写自己的客户端

package com.citigroup.ws.client;

import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axiom.soap.SOAP11Constants;
import org.apache.axis2.AxisFault;
import org.apache.axis2.Constants;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;

import cn.com.webxml.WeatherWebServiceStub;
import cn.com.webxml.WeatherWebServiceStub.ArrayOfString;

public class WeatherTest {

    /**
     * @param args
     * @throws Exception
     * @throws AxisFault
     */
    public static void main(String[] args) throws Exception {
        
        //2nd method to get weather
        WeatherWebServiceStub stub = new WeatherWebServiceStub();

        WeatherWebServiceStub.GetWeatherbyCityName getWeatherByCityName = new WeatherWebServiceStub.GetWeatherbyCityName();
        getWeatherByCityName.setTheCityName("上海");
        WeatherWebServiceStub.GetWeatherbyCityNameResponse rs = stub
                .getWeatherbyCityName(getWeatherByCityName);
        ArrayOfString arry = rs.getGetWeatherbyCityNameResult();
        String[] weatherArr = arry.getString();
        for (String result : weatherArr) {
            System.out.println(result);
        }

    }

方法2：不生成stub代码，通过OMElement 和endpoint访问


1、导入所需的axis2的jar

2、直接写客户端

package com.citigroup.ws.client;

import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axiom.soap.SOAP11Constants;
import org.apache.axis2.AxisFault;
import org.apache.axis2.Constants;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;

import cn.com.webxml.WeatherWebServiceStub;
import cn.com.webxml.WeatherWebServiceStub.ArrayOfString;

public class WeatherTest {

    /**
     * @param args
     * @throws Exception
     * @throws AxisFault
     */
    public static void main(String[] args) throws Exception {
        //first method to get weather
//        WeatherTest s = new WeatherTest();
//          s.getResult();
          System.out.println("---------------------------");
     

    }

    private static EndpointReference targetEPR = new EndpointReference(
            "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx");

    public void getResult() throws Exception {
        ServiceClient sender = new ServiceClient();
        sender.setOptions(buildOptions());
        OMElement result = sender.sendReceive(buildParam());
        System.out.println(result);
    }

    private static OMElement buildParam() {
        OMFactory fac = OMAbstractFactory.getOMFactory();
        OMNamespace omNs = fac.createOMNamespace("http://WebXml.com.cn/", "");
        OMElement data = fac.createOMElement("getWeatherbyCityName", omNs);
        OMElement inner = fac.createOMElement("theCityName", omNs);
        inner.setText("成都");
        data.addChild(inner);
        return data;
    }

    private static Options buildOptions() {
        Options options = new Options();
        options.setSoapVersionURI(SOAP11Constants.SOAP_ENVELOPE_NAMESPACE_URI);
        options.setAction("http://WebXml.com.cn/getWeatherbyCityName");
        options.setTo(targetEPR);
        // options.setProperty 如果不是通过代理上网，此句可省
        // options.setProperty(HTTPConstants.PROXY, buildProxy());
        options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
        return options;
    }
}
