java - Spring: WebServiceTransportException: Not Found [404] 对于非常简单的 WS 客户端

Question

我正在尝试为公开服务编写一个客户端。我只需要传递原始 XML(作为 Java 字符串)并查看原始响应。无需绑定(bind)。

服务在此公开:http://www.webservicex.net/periodictable

我验证了以下请求 XML 工作正常(通过 Soap UI):

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://www.webserviceX.NET">
   <soapenv:Header/>
   <soapenv:Body>
      <web:GetAtomicWeight>
         <!--Optional:-->
         <web:ElementName>Aluminium</web:ElementName>
      </web:GetAtomicWeight>
   </soapenv:Body>
</soapenv:Envelope>

我在这里使用Spring的WS模板，Maven依赖:

<dependency>
    <groupId>org.springframework.ws</groupId>
    <artifactId>spring-ws-core</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>

现在，这是我的简单“主”应用程序。它只是将 XML 字符串委托(delegate)给 Spring 的 WebServiceTemplate 并期望在 System.out 中看到结果。

package sk.xorty.ws;

import org.springframework.ws.client.core.WebServiceTemplate;
import org.springframework.ws.soap.client.core.SoapActionCallback;
import org.springframework.ws.soap.saaj.SaajSoapMessageFactory;

import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPConstants;
import javax.xml.soap.SOAPException;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import java.io.StringReader;

public class WsTest {

    private static final String REQUEST_PERIODIC =
            "<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:web=\"http://www.webserviceX.NET\">\n" +
            "   <soap:Header/>\n" +
            "   <soap:Body>\n" +
            "      <web:GetAtomicWeight>\n" +
            "         <web:ElementName>Aluminium</web:ElementName>\n" +
            "      </web:GetAtomicWeight>\n" +
            "   </soap:Body>\n" +
            "</soap:Envelope>\n";

    private static final String URL_PERIODIC = "http://www.webservicex.net/periodictable";

    private final WebServiceTemplate webServiceTemplate = new WebServiceTemplate();

    // send to an explicit URI
    public void customSendAndReceive() throws SOAPException {
        MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
        SaajSoapMessageFactory newSoapMessageFactory = new SaajSoapMessageFactory(messageFactory);
        webServiceTemplate.setMessageFactory(newSoapMessageFactory);

        StreamSource source = new StreamSource(new StringReader(REQUEST_PERIODIC));
        StreamResult result = new StreamResult(System.out);
        webServiceTemplate.sendSourceAndReceiveToResult(URL_PERIODIC, source,
                new SoapActionCallback("GetAtomicWeight"), result);
    }

    public static void main(String[] args) throws SOAPException {
        new WsTest().customSendAndReceive();
    }
}

示例是可运行的(它只需要类路径中的上述依赖项)。它抛出以下错误:

INFO: Creating SAAJ 1.3 MessageFactory with SOAP 1.1 Protocol

编辑: 请求的正确值是这个:

private static final String REQUEST_PERIODIC = "<web:GetAtomicWeight xmlns:web=\"http://www.webserviceX.NET\">\n" +
        "         <!--Optional:-->\n" +
        "         <web:ElementName>Aluminium</web:ElementName>\n" +
        "      </web:GetAtomicWeight>";

Answer 1

我认为你的问题与soapActionCallBack有关。您仅调用该操作，而不是使用 uri 调用该操作。以下是来自 here 的示例:

如果您备注命名空间为 http://tempuri.org 并且为soapActionCallback 提供的参数是 http://tempuri.org/SOAPACTION *

 WebServiceTemplate template = new WebServiceTemplate(messageFactory);
 Result result = new DOMResult();
 template.sendSourceAndReceiveToResult(
     new StringSource("<content xmlns=\"http://tempuri.org\"/>"),
     new SoapActionCallback("http://tempuri.org/SOAPAction"),
     result);

就您而言，肥皂操作应该是 http://www.webserviceX.net/GetAtomicWeight (不过我不太确定大小写)
