webservice系统学习笔记6-使用soap的header传递消息
1、显示的使用soap的header传递消息(不推荐使用,会破坏正常的代码结构,推荐使用handler处理)
@WebResult(name="deleteResult") public boolean deleteUser(@WebParam(header=true,name="adminName")String adminName,@WebParam(name="deleteName")String delName);
@Override public boolean deleteUser(String adminName, String delName) { return true; }
wsdl:
xsd文件
调用代码:
/** * 使用了SOAP的hearder来传递消息(缺点:会改变方法的参数定义) */ @Test public void test4(){ try { String namespace = "http://ws01.yzl.com/"; String wsdlUrl = "http://localhost:8888/ws01?wsdl"; //1、创建服务(Service) URL url = new URL(wsdlUrl); QName qname = new QName(namespace,"MyServiceImplService"); Service service = Service.create(url, qname); //2、创建Dispatch //public interface Dispatch<T>extends BindingProviderDispatch 接口提供对动态调用服务端点操作的支持。javax.xml.ws.Service 接口作为创建 Dispatch 实例的工厂。 Dispatch<SOAPMessage> dispatch = service.createDispatch(new QName(namespace,"MyServiceImplPort"), SOAPMessage.class, Service.Mode.MESSAGE); //3.1、创建SOAPMessage SOAPMessage message = MessageFactory.newInstance().createMessage(); SOAPEnvelope envelope = message.getSOAPPart().getEnvelope(); SOAPBody body = envelope.getBody(); //3.2、处理header信息 SOAPHeader header = envelope.getHeader(); if(header==null) header = envelope.addHeader(); QName hname = new QName(namespace,"adminName","nn"); header.addHeaderElement(hname).setValue("administrator"); //4、创建QName来指定消息中传递数据 QName ename = new QName(namespace,"deleteUser","nn"); body.addBodyElement(ename); message.writeTo(System.out);
System.out.println(); //5、通过Dispatch传递消息,并返回响应消息 SOAPMessage returnMessage = dispatch.invoke(message); returnMessage.writeTo(System.out);//打印返回消息 System.out.println(); //5、解析返回的SOAP消息的XML Document doc = returnMessage.getSOAPBody().extractContentAsDocument(); //Document doc = returnMessage.getSOAPPart().getEnvelope().getBody().extractContentAsDocument(); String result = doc.getElementsByTagName("deleteResult").item(0).getTextContent(); System.out.println("result is :" + result); } catch (Exception e) { e.printStackTrace(); } }
结果:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header><nn:adminName xmlns:nn="http://ws01.yzl.com/">administrator</nn:adminName></SOAP-ENV:Header>
<SOAP-ENV:Body><nn:deleteUser xmlns:nn="http://ws01.yzl.com/"/></SOAP-ENV:Body>
</SOAP-ENV:Envelope> <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Header/>
<S:Body>
<ns2:deleteUserResponse xmlns:ns2="http://ws01.yzl.com/"><deleteResult>true</deleteResult></ns2:deleteUserResponse>
</S:Body>
</S:Envelope> result is :true
