Question

任何人都可以帮我开发一个与web服务交互的java程序。

我在netbeans中创建了一个简单的web服务。它会生成wsdl文件，然后从中获取url。

通过使用在netbeans中创建的wsdl文件，我必须在java程序中发送soap请求并获取响应。

我有以下编码，但我不知道如何实现我的要求

import javax.xml.soap.*;

public class SOAPClientSAAJ2 {
    public static void main(String args[]) throws Exception {
        // 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);

        // print SOAP Response
        System.out.print("Response SOAP Message:");
        soapResponse.writeTo(System.out);

        soapConnection.close();
    }

    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;
    }
}

我建议使用JAX-WS而不是手工制作SOAP消息。使用JAX-WS，您可以生成用于创建SOAP / XML以及发送/接收消息/响应的代码。您剩下要做的就是设置您需要传递的内容的值。在这种情况下，将创建一个VerifyEmail对象，设置其两个属性并调用生成的Web服务客户端的send方法：

ObjectFactory factory = new ObjectFactory;
VerifyEmailRequest request = objectFactory.createVerifyEmailRequest();
VerifyEmail msg = objectFactory.createVerifyEmail();
msg.setEmail("myemail@provider.com");
msg.setLicenseKey("myKey");
request.setVerifyEmail(msg);
VerifyEmailResponse response = myClient.verifyEmail(reques);

这里提到的所有类都将由JAXB为您生成，JAXB使用它。您可以找到更详细的信息here。
