Question

嘿那里，我一直在使用JWSDL来允许我以编程方式使用WSDL文件。我现在想要创建可以发送到服务器的SOAP请求。如何从JWSDL类生成这些请求？有任何想法吗？

谢谢！

你可以这样做：

在这里，我创建了一个带有两个参数的示例Web服务 number1和number2。并将响应作为number3（= number1 + 2号）。 Web服务已部署在localhost：8080（tomcat 服务器）

您的答案从此处开始。

我创建了一个示例java文件...它将两个参数传递给a SOAP请求中的Web服务，并从Web获取SOAP响应服务。您可以从WSDL文件中获取参数（在代码中描述），如getCalculation，m，localhost：8080，number1，number2和url。

示例代码：

package SampleJavaWSDLDemo;

import javax.xml.soap。*;
import java.util。*;
import java.net.URL;
import javax.xml.transform。*;
import javax.xml.transform.stream.StreamResult;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPBody;
import java.net.URL;

public static void main(String[] args) 
{
    try {

    //Create a SOAPMessage
    SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
    SOAPConnection connection = soapConnectionFactory.createConnection();
    SOAPFactory soapFactory = SOAPFactory.newInstance();
    MessageFactory factory = MessageFactory.newInstance();
    SOAPMessage message = factory.createMessage();
    SOAPHeader header = message.getSOAPHeader();
    SOAPBody body = message.getSOAPBody();
    header.detachNode();

    Name bodyName = soapFactory.createName("getCalculation", "m", "http://localhost:8080/");
    SOAPBodyElement bodyElement = body.addBodyElement(bodyName);

            //Insert Content
    Name name = envelope.createName("number1");
    SOAPElement symbol = bodyElement.addChildElement(name);
    symbol.addTextNode("10");
    name = envelope.createName("number2");
    symbol = bodyElement.addChildElement(name);
    symbol.addTextNode("20");

            System.out.println("\n Request: \n");
            message.writeTo(System.out);
            System.out.println();

            // Create an endpint point which is either URL or String type
    URL endpoint = new URL("http://localhost:8080/WebServiceName/OperationName");

            //Send a SOAPMessage (request) and then wait for SOAPMessage (response)
    SOAPMessage response = connection.call(message, endpoint);

    // Get the response from the webservice.                
    SOAPBody soapBody = response.getSOAPBody();

    System.out.println("\n Response: \n");
    TransformerFactory transformerfactory = TransformerFactory.newInstance();
    Transformer transformer = transformerfactory.newTransformer();
    Source sourceContent = response.getSOAPPart().getContent();
    StreamResult result = new StreamResult(System.out);
    transformer.transform(sourceContent, result);
    System.out.println();
    String resp = response.getSOAPBody().getElementsByTagName("return").item(0).getFirstChild().getNodeValue();
    System.out.println("Answer is: " + resp);

    connection.close();

    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

}

尝试运行此代码。它可以为您提供完整的肥皂请求和响应消息。
