在JAVA中，如何从SOAP Web服务请求、将SOAP响应转换为XML并将其与另一个SOAP响应进行比较

Question

我完全不熟悉这三个步骤，所以你能一步一步地帮我吗。（我懂Java语言，在这里和那里编写了两个脚本，但从未接触过SOAP内容）。 我需要这样做：

1）从两个SOAP服务请求并将响应存储在两个对象中

2）转换XML中的响应（可能，可能不，取决于输出是否为 <；标签></标签>； 那么不需要转换，但如果是 <；n32：标签>&书信电报；n32：标签>； 然后我会想摆脱“n32”

3）比较这两个响应，看看节点/标记和内部标记级别的差异在哪里（可能使用XMLUnit）

4）在控制台中报告差异。（不是JUnit中的错误）

谢谢

1. 由于您有webservice端点，我建议您为每个服务创建webservice客户端

您可以使用JDK附带的wsimport来实现这一点：

wsimport.bat -d "D:\WS" -keep -verbose endpoint_ws.wsdl
pause

执行此命令后，您将有java对象来访问Web服务

将这些对象放在项目中并访问webservice

以下是如何操作的参考：

JAXWS

1. 既然已经有了响应的对象，就可以对每个属性进行编码和比较了。 如果需要再次将这些对象转换为xml进行比较（我再说一遍，因为SOAP消息已经是xml），可以使用xstream（http://x-stream.github.io/tutorial.html）

如果您不需要处理java客户机对象，可以遵循以下内容：

How to do a SOAP Web Service call from Java class?

在文章的第二部分中，展示了如何直接与请求/响应消息进行交互：

import javax.xml.soap.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;

public class SOAPClientSAAJ {

    /**
     * Starting point for the SAAJ - SOAP Client Testing
     */
    public static void main(String args[]) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server
            String url = "http://ws.cdyne.com/emailverify/Emailvernotestemail.asmx";
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);

            // Process the SOAP Response
            printSOAPResponse(soapResponse);

            soapConnection.close();
        } catch (Exception e) {
            System.err.println("Error occurred while sending SOAP Request to Server");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest() throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String serverURI = "http://ws.cdyne.com/";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration("example", serverURI);

        /*
        Constructed SOAP Request Message:
        <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:example="http://ws.cdyne.com/">
            <SOAP-ENV:Header/>
            <SOAP-ENV:Body>
                <example:VerifyEmail>
                    <example:email>mutantninja@gmail.com</example:email>
                    <example:LicenseKey>123</example:LicenseKey>
                </example:VerifyEmail>
            </SOAP-ENV:Body>
        </SOAP-ENV:Envelope>
         */

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("VerifyEmail", "example");
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("email", "example");
        soapBodyElem1.addTextNode("mutantninja@gmail.com");
        SOAPElement soapBodyElem2 = soapBodyElem.addChildElement("LicenseKey", "example");
        soapBodyElem2.addTextNode("123");

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", serverURI  + "VerifyEmail");

        soapMessage.saveChanges();

        /* Print the request message */
        System.out.print("Request SOAP Message = ");
        soapMessage.writeTo(System.out);
        System.out.println();

        return soapMessage;
    }

    /**
     * Method used to print the SOAP Response
     */
    private static void printSOAPResponse(SOAPMessage soapResponse) throws Exception {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        Source sourceContent = soapResponse.getSOAPPart().getContent();
        System.out.print("\nResponse SOAP Message = ");
        StreamResult result = new StreamResult(System.out);
        transformer.transform(sourceContent, result);
    }

}

要直接从字符串创建soap消息，首先创建InputStream

InputStream is = new ByteArrayInputStream(send.getBytes());
SOAPMessage request = MessageFactory.newInstance().createMessage(null, is);
