我正在尝试将 SOAP 调用集成到我的 Java 应用程序中。我已经在线学习了各种教程，但是当我运行应用程序时，它会给出错误，sm.saveChanges()如果该行被注释掉，它会给出错误sm.writeTo(System.out)。

下面是代码：

//Create a SOAPConnection   
          SOAPConnectionFactory sfc = SOAPConnectionFactory.newInstance();
          SOAPConnection connection = sfc.createConnection();

          MessageFactory mf = MessageFactory.newInstance();
          SOAPMessage sm = mf.createMessage();
          SOAPPart sp = sm.getSOAPPart();
          SOAPEnvelope sv = sp.getEnvelope();

          SOAPHeader sh = sm.getSOAPHeader();
          //SOAPHeaderElement headerElement = sh.addHeaderElement(sv.createName("Signature", "SOAP-SEC", "http://schemas.xmlsoap.org/soap/security/2000-12"));

          SOAPBody sb = sm.getSOAPBody();

          //sh.detachNode();


          MimeHeaders headers = sm.getMimeHeaders();
          headers.addHeader("SOAPAction", "\"\""); 
          //QName bodyName = new QName("http://quoteCompany.com", "GetQuote", "d");
          //QName bodyName = new QName(msisdn, "GetRioInformationsRequest", "ser");
          //QName bodyName = new QName("http://schemas.xmlsoap.org/soap/encoding/", "GetRioInformationsRequest", XMLConstants.DEFAULT_NS_PREFIX);
          QName bodyName = new QName("http://quoteCompany.com/", "GetQuote", "ser");
          //QName bodyName = sv.createQName("http://quoteCompany.com/", "GetQuote", "ser");
          Name  bodyName2 = sv.createName("GetQuote","ser", "http://quoteCompany.com/");
          SOAPBodyElement bodyElement = sb.addBodyElement(bodyName2);
          //QName qn = new QName("aName");
          //Name qn = sv.createName("rioSearchRequest");
          QName qn = new QName("returnCode");

          SOAPElement quotation = bodyElement.addChildElement(qn);
          //quotation.addChildElement(qn2);

          //Name qn2 = sv.createName("msisdn");
          //qn2.
          //quotation.addAttribute(qn2, msisdn);
          //quotation.addTextNode("TextMode");
          quotation.addTextNode(msisdn);

          System.out.println("Saving SOAP message.");
          sm.saveChanges();
          System.out.println("\n Soap Request:\n");
          sm.writeTo(System.out);
          System.out.println("Request Outputted for viewing.");

          //URL endpoint = new URL("http://yourServer.com");
          URL endpoint = new URL("http://127.0.0.1:8088/mockSoapBinding");
          System.out.println("URL entered.");
          SOAPMessage response = connection.call(sm, endpoint);
          System.out.println("Resquest Sent!");
          System.out.println(response.getContentDescription());
          System.out.println("Response obtained!");

相应的错误是：

有什么建议么？

您真的不想手动执行此操作。生成一个 Web 服务客户端并使用该客户端。

您可以使用Apache Axis WSDL2Code。还有其他选项可以生成客户端。例如 Eclipse 有一个内置的工具可以做到这一点。

同意 Udo Held 等人的观点。只想提一下，如果您真的想在如此低的级别上集成 SOAP 调用，您可以首先使用 Apache Axis 来完成，而不是使用调试和 http 数据包跟踪工具进行一些调查以找出您遗漏的内容。例如，当您尝试使用 XPath 从 SOAP 响应中拉出单个节点而不首先将其绑定到 POJO 对象时，这种方式对于某些特定情况来说是值得的。

正如@Udo Held 所提到的，您不想手动构建SOAP 请求。

请参阅此问题的答案：如何从 SOAP 获得响应？

您可以使用该wsimport工具自动生成连接到 SOAP 服务所需的所有代码。

wsimport随 JDK 一起提供，因此您已经在系统上安装了它（无需额外下载）并假设 Java 在您的路径上，您可以转到任何终端并键入：

wsimport http://www.url.to.wsdl.asmx?wsdl -p com.whateveruwant -Xnocompile -d . -keep

完成此操作后，您将能够非常简单地使用自动生成的代码调用 Web 服务，例如：

CustomInterface soap = new CustomEndpoint().getCustomInterface();
System.out.println(soap.getAnswerFromWs("ParamValue"));
