SOAP消息格式与处理方式

soap消息的创建
//1、创建消息工厂 
MessageFactory factory = MessageFactory.newInstance(); 
//2、根据消息工厂创建SoapMessage 
SOAPMessage message = factory.createMessage(); 
//3、创建SOAPPart 
SOAPPart part = message.getSOAPPart(); 
//4、获取SOAPENvelope 
SOAPEnvelope envelope = part.getEnvelope(); 
//5、可以通过SoapEnvelope有效的获取相应的Body和Header等信息 
SOAPBody body = envelope.getBody(); 
//6、根据Qname创建相应的节点(QName就是一个带有命名空间的节点) 
//<ns:add xmlns="http://java.zttc.edu.cn/webservice"/> 
QName qname = new QName("http://java.zttc.edu.cn/webservice", "add","ns"); 
//如果使用以下方式进行设置，会见<>转换为&lt;和&gt 
//body.addBodyElement(qname).setValue("<a>1</a><b>2</b>"); 
SOAPBodyElement ele = body.addBodyElement(qname); 
ele.addChildElement("a").setValue("22"); ele.addChildElement("b").setValue("33"); 
//打印消息信息 
message.writeTo(System.out);

消息传递

//1、创建服务(Service) 
URL url = new URL(wsdlUrl); 
QName sname = new QName(ns,"MyServiceImplService"); 
Service service = Service.create(url,sname); 
             
//2、创建Dispatch 
Dispatch<SOAPMessage> dispatch = service.createDispatch(new QName(ns,"MyServiceImplPort"),SOAPMessage.class,Service.Mode.MESSAGE); 
             
//3、创建SOAPMessage 
SOAPMessage msg = MessageFactory.newInstance().createMessage(); 
SOAPEnvelope envelope = msg.getSOAPPart().getEnvelope(); 
SOAPBody body = envelope.getBody(); 
             
//4、创建QName来指定消息中传递数据 
QName ename = new QName(ns,"add","nn");//<nn:add xmlns="xx"/> 
SOAPBodyElement ele = body.addBodyElement(ename); 
ele.addChildElement("a").setValue("22"); 
ele.addChildElement("b").setValue("33"); 
msg.writeTo(System.out); 
System.out.println("\n invoking....."); 
                     
//5、通过Dispatch传递消息,会返回响应消息 
SOAPMessage response = dispatch.invoke(msg); 
response.writeTo(System.out); 
System.out.println(); 
             
//6、响应消息处理,将响应的消息转换为dom对象 
Document doc = response.getSOAPPart().getEnvelope().getBody().extractContentAsDocument(); 
String str = doc.getElementsByTagName("addResult").item(0).getTextContent(); 
System.out.println(str);
