Java调用WebService接口--SOAPMessage组装参数

本文主要是介绍Java调用WebService接口--SOAPMessage组装参数，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

使用SOAPMessage进行WebService接口调用需要自己构造请求参数，需要按照一定的顺序，按照一定的层级关系添加组装成xml格式报文。一下是示例代码。

使用demo代码

package cn.hewie.webService.client;import com.sun.xml.internal.ws.client.BindingProviderProperties;
import com.sun.xml.internal.ws.developer.JAXWSProperties;
import org.w3c.dom.Document;import javax.xml.namespace.QName;
import javax.xml.soap.*;
import javax.xml.ws.Dispatch;
import java.net.URL;
import java.util.HashMap;public class SoapRequest {public void execute() throws Exception {String nameSpace = "http://tempuri.org/";String wsdlUrl = "https://infotrack.naqelexpress.com/NaqelAPIServices/NaqelAPIDemo/5.0/XMLShippingService.asmx?WSDL";String serviceName = "XMLShippingService";String portName = "XMLShippingServiceSoap12";String elementName = "IsWaybillExists";String responseName = "IsWaybillExistsResponse";// 1.create serviceURL url = new URL(wsdlUrl);QName sname = new QName(nameSpace, serviceName);javax.xml.ws.Service service = javax.xml.ws.Service.create(url, sname);// 2.create Dispatch objectDispatch<SOAPMessage> dispatch = service.createDispatch(new QName(nameSpace, portName), SOAPMessage.class, javax.xml.ws.Service.Mode.MESSAGE);// 3.create SOAPMessageSOAPMessage msg = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage();msg.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, "UTF-8");// 3.1 create SOAPEnvelopeSOAPEnvelope envelope = msg.getSOAPPart().getEnvelope();envelope.setPrefix("soap");envelope.addNamespaceDeclaration("tem", nameSpace);envelope.removeAttribute("xmlns:env");// 3.2 create SOAPHeaderSOAPHeader header = envelope.getHeader();if (null == header) {header = envelope.addHeader();}header.setPrefix("soap");// 3.3 create SOAPBodySOAPBody body = envelope.getBody();body.setPrefix("soap");SOAPBodyElement clientInfo = body.addBodyElement(new QName(nameSpace, "ClientInfo", "tem"));clientInfo.addChildElement(new QName(nameSpace, "ClientID", "tem")).setValue("1");clientInfo.addChildElement(new QName(nameSpace, "Password", "tem")).setValue("111");clientInfo.addChildElement(new QName(nameSpace, "Version", "tem")).setValue("1.0");SOAPBodyElement ele = body.addBodyElement(new QName(nameSpace, elementName, "tem"));ele.addChildElement(clientInfo);ele.addChildElement(new QName(nameSpace, "WaybillNo", "tem")).setValue("111");// ...msg.writeTo(System.out); // print xmlSystem.out.println("\n----------");// set timeoutdispatch.getRequestContext().put(BindingProviderProperties.CONNECT_TIMEOUT, 2000);dispatch.getRequestContext().put(JAXWSProperties.REQUEST_TIMEOUT, 2000);SOAPMessage response = dispatch.invoke(msg);// 4. get response and transfer to dom objectDocument doc = response.getSOAPPart().getEnvelope().getBody().extractContentAsDocument();String result = doc.getElementsByTagName(responseName).item(0).getTextContent();System.out.println(result);}}

上例中一些变量值的获取肯定让人有点摸不着头脑，我们可以通过wsdl文档获取到其中的参数变量的值。

参数获取途径

以下是使用soapUI打开的wsdl文档，并发送的一条请求，示例代码中的变量标识如下：
SOAP参数获取

样例结果

调用上述execute方法，样例结果如下：

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tem="http://tempuri.org/"><soap:Header/><soap:Body><tem:IsWaybillExists><tem:ClientInfo><tem:ClientID>1</tem:ClientID><tem:Password>111</tem:Password><tem:Version>1.0</tem:Version></tem:ClientInfo><tem:WaybillNo>111</tem:WaybillNo></tem:IsWaybillExists></soap:Body>
</soap:Envelope>
----------
true
