axis2通过城市名称调用.net写的asmx WebService查询天气实例

注释是自己的理解。。

package com.jielan.axis2;

public class Client01 {
   private static String url = "http://webservice.webxml.com.cn/WebServices/WeatherWebService.asmx";
   //端点引用指接口位置
   private static EndpointReference targetEpr = new EndpointReference(url);
   //有抽象OM工厂获取OM工厂，创建request SOAP包
   private static OMFactory fac = OMAbstractFactory.getOMFactory();

   public static OMElement getOMMethod(String methodStr,String namespace,String tns,String[] pars,String[] vals){
       //创建命名空间
       OMNamespace nms = fac.createOMNamespace(namespace, tns);
       //创建OMElement方法元素，并指定其在nms指代的名称空间中
       OMElement method = fac.createOMElement(methodStr, nms);
       //添加方法参数名和参数值
       for(int i=0;i<pars.length;i++){
           //创建方法参数OMElement元素
           OMElement param = fac.createOMElement(pars[i],nms);
           //设置键值对参数值
           param.setText(vals[i]);
           //讲方法元素添加到method方法元素中
           method.addChild(param);
       }
       return method;
   }

   public static Options getClientOptions(String action){
       //创建request soap包请求选项
       Options options = new Options();
       //设置options的soapAction
       options.setAction(action);
       //设置request soap包的端点引用(接口地址)
       options.setTo(targetEpr);
       //如果报错提示Content-Length，请求内容长度
       options.setProperty(HTTPConstants.CHUNKED,"false");//把chunk关掉后，会自动加上Content-Length。
       return options;

}

   public static OMElement getWeather(String action,String methodStr,String namespace,String tns,String[] pars,String[] vals){
       OMElement result = null;
       try {
           ServiceClient client = new ServiceClient();
           client.setOptions(getClientOptions(action));
           result = client.sendReceive(getOMMethod(methodStr,namespace,tns,pars,vals));
       } catch (AxisFault e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
       return result;

}

  public static void main(String[] args) {
       String action = "http://WebXml.com.cn/getWeatherbyCityName";
       String methodStr = "getWeatherbyCityName";
       String namespace = "http://WebXml.com.cn/";
       String tns = "xsd";
       String[] pars = {"theCityName"};
       String[] vals = {"杭州"};
       OMElement result = null;
       result = getWeather(action, methodStr, namespace, tns, pars, vals);
       System.out.println(result);
   }

}

查看namespace

查看端点引用指接口位置接口地址

查看调用方法名和 soapAction的action地址

另外OMElement method = fac.createOMElement(methodStr, nms);第二个参数nms 具体是什么好像随便填，""也行

不过查了很多看到有人说这是服务名。。

这里只要不填已有的变量名，遇到变量重复定义错误，就都可以。。

结果:

index.jsp上调用

<body>
    <%
       //out.print(InvokeExercise.invokeWucan().replaceAll("</string>", "</string>\r<br/>"));
       //out.print(InvokeExercise.invokeYouCan());
       out.print(Client01.getWeather(
               "http://WebXml.com.cn/getWeatherbyCityName",
               "getWeatherbyCityName","http://WebXml.com.cn/",
               "xsd",new String[]{"theCityName"},
               new String[]{"台州"}).toString().replaceAll("。", "。<br/>").replaceAll("今日天气实况", "<br/>今日天气实况"));
    %>
</body>

web上调用结果 :
