Question

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

以下是代码：

//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：

有什么建议吗？

Answer 1

你真的不想亲手做到这一点。生成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built in tool这样做。

Answer 2

同意Udo Held和其他人的意见。只是想提一下，如果你真的想要在如此低级别上集成SOAP调用，你可以先使用Apache Axis进行调查，而不是使用调试和http数据包跟踪工具进行一些调查，以找出你错过的内容。这种方式值得在某些特定情况下遇到麻烦，例如，您尝试使用XPath从SOAP响应中提取单个节点，而不是首先将其绑定到POJO对象。

Answer 3

正如@Udo Held所提到的，你不想手工构建SOAP请求。

请参阅此问题的答案：How to get response from SOAP?

您可以使用wsimport工具自动生成连接SOAP服务所需的所有代码。

wsimport附带JDK，因此您已经在系统上安装了它（没有额外的下载）并且假设Java在您的路径上，您可以转到任何终端并输入：

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

这样做，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"));
