在java中从WS中检索正确的数据

Question

我在这个 WSDL 上运行了 wsimport

http://ws.dati.comune.milano.it/opendata/wsopendata.asmx?WSDL

并生成客户端 JAX-WS 类。

现在我想使用getOpenWifi

使用这个 sn-p ：

        String message = " ";
        WSOpenData wsopendata = new WSOpenData();
        GetOpenWifiResult result = wsopendata.getWSOpenDataSoap().getOpenWifi(" ");
        List<Object> list = result.getContent();
        for (Iterator<Object> iterator = list.iterator(); iterator.hasNext();) {

            message += iterator.next().toString() + " ";
        }

我将message 获取为

 [NewDataSet: null] 

我认为我做错了什么，我该如何检索正确的数据集？

当我用 SoapUI 调用它时，我得到类似的东西

    <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <getOpenWifiResponse xmlns="http://comune.milano.it/">
         <getOpenWifiResult>
            <NewDataSet xmlns="">
               <Table>
                  <ID>3</ID>
                  <Sito>Arco Della Pace</Sito>
                  <Zona>1</Zona>
                  <Attiva>1</Attiva>
                  <Codice>A0044</Codice>
                  <Coordinate>9.172460,45.475670,0.000000</Coordinate>
               </Table>
               <Table>
                  <ID>4</ID>
                  <Sito>Bastioni di Porta Nuova 23</Sito>
                  <Zona>1</Zona>
                  <Attiva>1</Attiva>
                  <Codice>E0725</Codice>
                  <Coordinate>9.192273,45.478577,0.000000</Coordinate>
               </Table>

我认为“NewDataSet”-Object 会有子对象“table”。检查生成的人工制品（我没有）

€dit： 试试看

import it.milano.comune.GetOpenWifiResponse.GetOpenWifiResult;
import it.milano.comune.WSOpenData;

import java.net.URL;

import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;


public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {
        WSOpenData ws = new WSOpenData(new URL("http://ws.dati.comune.milano.it/opendata/wsopendata.asmx?WSDL"));

        GetOpenWifiResult rw = ws.getWSOpenDataSoap().getOpenWifi(" ");
        for (Object o : rw.getContent()) {
            System.out.println(o.getClass().getName());
            Element e = (Element) o;
            NodeList c = e.getChildNodes();

            System.out.println(c);
            for (int i = 0; i < c.getLength(); i++) {
                Node table = c.item(i);

                System.out.println("tab");

                for (int i2 = 0; i2 < table.getChildNodes().getLength(); i2++) {
                    Node property = table.getChildNodes().item(i2);
                    System.out.println("\tp: " + property);
                }

            }

        }

        long x = 1;
    }

}

它给了我

我敢肯定，如果您尝试一下，您将能够解决它
