Java工作Soap客户端示例

我试图在JAVA中找到一个简单的（ha）带有工作服务的SOAP示例，但我似乎找不到的任何例子。

我已经试过这一个，从这个例子，但它只是不工作，它要求我把一个斜杠的，但它在那里并没有什么发生。

那么，有谁知道任何SOAP示例链接，我可以下载/请求并使用它吗？

谢谢你的帮助。

回答：

要用Java实现简单的SOAP客户端，可以使用SAAJ框架（JSE 1.6及更高版本附带）：

带有Java附件API的SOAP（SAAJ）主要用于直接处理任何Web Service API幕后发生的SOAP请求/响应消息。它允许开发人员直接发送和接收肥皂消息，而不是使用JAX-WS。

参见下面使用SAAJ进行SOAP Web服务调用的工作示例（运行它！）。它称为此Web服务。

import javax.xml.soap.*;
public class SOAPClientSAAJ {
    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*
            The example below requests from the Web Service at:
             http://www.webservicex.net/uszip.asmx?op=GetInfoByCity
            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action
            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "http://www.webservicex.net/uszip.asmx";
        String soapAction = "http://www.webserviceX.NET/GetInfoByCity";
        callSoapWebService(soapEndpointUrl, soapAction);
    }
    private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();
        String myNamespace = "myNamespace";
        String myNamespaceURI = "http://www.webserviceX.NET";
        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);
            /*
            Constructed SOAP Request Message:
            <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:myNamespace="http://www.webserviceX.NET">
                <SOAP-ENV:Header/>
                <SOAP-ENV:Body>
                    <myNamespace:GetInfoByCity>
                        <myNamespace:USCity>New York</myNamespace:USCity>
                    </myNamespace:GetInfoByCity>
                </SOAP-ENV:Body>
            </SOAP-ENV:Envelope>
            */
        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("GetInfoByCity", myNamespace);
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("USCity", myNamespace);
        soapBodyElem1.addTextNode("New York");
    }
    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();
            // Send SOAP Message to SOAP Server
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl);
            // Print the SOAP Response
            System.out.println("Response SOAP Message:");
            soapResponse.writeTo(System.out);
            System.out.println();
            soapConnection.close();
        } catch (Exception e) {
            System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
            e.printStackTrace();
        }
    }
    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();
        createSoapEnvelope(soapMessage);
        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", soapAction);
        soapMessage.saveChanges();
        /* Print the request message, just for debugging purposes */
        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");
        return soapMessage;
    }
}
