webservice初级

在学习webservice的时候，经常将ns和url花了好久时间才理解过来，这里备份下！

首先定义接口：

@WebService

public interface IService

{

@WebResult(name = "login")

public User login(@WebParam(name = "username") String username,

@WebParam(name = "password") String password);

}

创建实现类：

@WebService(endpointInterface = "com.cml.soap.IService[这里是实现接口的全路径]", name = "myname")

public class ServiceImpl implements IService

{

@Override

@WebResult(name = "login")

public User login(@WebParam(name = "username") String username,

@WebParam(name = "password") String password)

{

System.out.println("进来登录");

return new User("恭喜你登录成功！", 1);

}

}

发布服务：

String address = "http://localhost:8888/cml";

Endpoint.publish(address, new ServiceImpl());

在浏览器上输入http://localhost:8888/cm?wsdl

创建soap消息：

public void sendSoap() throws Exception

{

String ns = "http://soap.cml.com/";

QName name = new QName(ns, "ServiceImplService");



String url = "http://localhost:8888/cml?wsdl";

// 使用的是url进行服务的创建

Service service = Service.create(new URL(url), name);





Dispatch<SOAPMessage> dispatch = service.createDispatch(new QName(ns,

"mynamePort"), SOAPMessage.class, Service.Mode.MESSAGE);





SOAPMessage msg = MessageFactory.newInstance().createMessage();

SOAPEnvelope ele = msg.getSOAPPart().getEnvelope();

SOAPBody body = ele.getBody();





QName name2 = new QName(ns, "login", "tns");// <tns:login xmlns=""

SOAPBodyElement element = body.addBodyElement(name2);

element.addChildElement("username").setValue("1111");

element.addChildElement("password").setValue("222");

msg.writeTo(System.out);

SOAPMessage response = dispatch.invoke(msg);

System.out.println("\n服务器响应回来");

response.writeTo(System.out);

// 获取返回信息的文档对象

Document document = response.getSOAPPart().getEnvelope().getBody()

.extractContentAsDocument();

System.out.println();



System.out.println(document.getElementsByTagName("login").item(0)

.getTextContent());



}
