webService之（二）java原生态客户端

wsimport -keep -p com.xyj.client http://localhost:8889/ms?wsdl[/code]命令参数说明： 
　　-d:生成客户端执行类的class文件的存放目录

　　-s:生成客户端执行类的源文件的存放目录

　　-p:定义生成类的包名

　　其他命令参数请参照：http://download-llnw.oracle.com/javase/6/docs/technotes/tools/share/wsimport.html

如图：



将上述生成的文件拷贝到项目中，即可使用。

客户端调用有两种方式:

一、利用生成的客户端代码

@Test
public void test001() throws Exception{

QName qname = new QName("http://web.xyj.com/", "PersonServiceService");
URL url = new URL("http://localhost:8889/ms?wsdl");

IPersonService service = new PersonServiceService().getPersonServicePort();

Person person = service.getPersonInfos();

System.out.println("name:" + person.getName() + ",sex:" + person.getSex() + ",email:" + person.getEmail());
}


二、发soap消息

1、java api生成soap消息串

@Test
public void test002() throws Exception {

URL url = new URL("http://localhost:8889/ms?wsdl");

QName qn = new QName("http://web.xyj.com/", "PersonServiceService");

Service service = Service.create(url, qn);

//创建Dispatch
Dispatch<SOAPMessage> dispatch = service.createDispatch(new QName(
"http://web.xyj.com/", "PersonServicePort"),
SOAPMessage.class, Service.Mode.MESSAGE);

//拼装请求消息串
SOAPMessage message = MessageFactory.newInstance().createMessage();

SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();

SOAPBody body = envelope.getBody();

QName eName = new QName("http://web.xyj.com/", "getPersonInfos", "ns");
SOAPBodyElement ele = body.addBodyElement(eName);

//拼装参数
//ele.addChildElement("count").setValue("9");
message.writeTo(System.out);
System.out.println("-------------");

SOAPMessage response = dispatch.invoke(message);
response.writeTo(System.out);
System.out.println();

Document doc =  response.getSOAPBody().extractContentAsDocument();
NodeList nl = doc.getElementsByTagName("person");
JAXBContext ctx = JAXBContext.newInstance(com.xyj.test.Person.class);

for (int i = 0; i < nl.getLength(); i++) {

Node n = nl.item(i);

com.xyj.test.Person person = (com.xyj.test.Person) ctx.createUnmarshaller().unmarshal(n);
System.out.println("name:" + person.getName() + ",sex:" + person.getSex() + ",email:" + person.getEmail());
}

System.out.println("\n================");

for (int i = 0; i < nl.getLength(); i++) {

Element elem = (Element) nl.item(i);

Node name = elem.getElementsByTagName("name").item(0);
Node sex = elem.getElementsByTagName("sex").item(0);
Node email = elem.getElementsByTagName("email").item(0);
System.out.println("name:" + name.getTextContent() + ",sex:" + sex.getTextContent() + ",email:" + email.getTextContent());
}
}


2、直接拼接soap消息串

@Test
public void test003() throws Exception{

URL url = new URL("http://localhost:8889/ms?wsdl");
QName sname = new QName("http://web.xyj.com/", "PersonServiceService");

Service service = Service.create(url, sname);

Dispatch<Source> dispatch = service.createDispatch(new QName("http://web.xyj.com/",
"PersonServicePort"), Source.class, Service.Mode.PAYLOAD);

System.out.println("=====================");

/**
* 封装相应的part getPersonInfos，如有参数，也想应装载
* 可以通过Marshaller列化回 XML数据
* com.xyj.test.Person person = new com.xyj.test.Person();
* person.setName("123");
*
* JAXBContext ctx = JAXBContext.newInstance(com.xyj.test.Person.class);
* Marshaller mar = ctx.createMarshaller();
* mar.setProperty(Marshaller.JAXB_FRAGMENT, true);
* StringWriter writer = new StringWriter();
* mar.marshal(person, writer);
*
*/
String payload = "<ns:getPersonInfos xmlns:ns=\"" + "http://web.xyj.com/" + "\">" + "</ns:getPersonInfos>";
System.out.println(payload);
StreamSource rs = new StreamSource(new StringReader(payload));

//通过dispatch传递payload
Source response = (Source) dispatch.invoke(rs);

//将Source转化为DOM进行操作，使用Transform对象转换
Transformer tran = TransformerFactory.newInstance().newTransformer();
DOMResult result = new DOMResult();
tran.transform(response, result);

//处理相应信息(通过xpath处理)
XPath xpath = XPathFactory.newInstance().newXPath();
NodeList nl = (NodeList) xpath.evaluate("//person", result.getNode(), XPathConstants.NODESET);
JAXBContext ctx = JAXBContext.newInstance(com.xyj.test.Person.class);
com.xyj.test.Person person = (com.xyj.test.Person) ctx.createUnmarshaller().unmarshal(nl.item(0));

System.out.println("name:" + person.getName() + ",sex:" + person.getSex() + ",email:" + person.getEmail());
}

Person.java

//一定要标为XmlRootElement
@XmlRootElement
public class Person {
private String name;
private String sex;
private String email;
//get\set
}
