新建一个User类：

packagecom.zhutulang.soap; importjavax.xml.bind.annotation.XmlRootElement;@XmlRootElementpublic class User {    private String name;   private String pwd;   private int age;   public User() {      super();   }   public User(String name, String pwd, int age) {      super();      this.name = name;      this.pwd = pwd;      this.age = age;   }    @Override   public String toString() {      return "[name:"+name+",pwd:"+pwd+",age:"+age+"]";   }   public String getName() {      return name;   }    public void setName(String name) {      this.name = name;   }   public String getPwd() {      return pwd;   }   public void setPwd(String pwd) {      this.pwd = pwd;   }   public int getAge() {      return age;   }   public void setAge(int age) {      this.age = age;   }}

然后在接口中新增一个方法：

@WebResult(name="user")   public User addUser(@WebParam(name="user")User user);

接口实现很简单，就是把一个user加入list中

packagecom.zhutulang.soap; importjava.util.ArrayList;importjava.util.List; importjavax.jws.WebService; @WebService(endpointInterface="com.zhutulang.soap.MyServiceInter")public class MyServiceInterImpl implements MyServiceInter {    private List<User> users = new ArrayList<User>();     @Override   public int add(int a, int b) {      System.out.println("a+b"+(a+b));      return a+b;   }    @Override   public User addUser(User user) {      users.add(user);      return user;   }}Test方法：   /**    * <p>Title: 通过payload发送消息<／p>    * <p>Description: <／p>    * @throws MalformedURLException    * @throws JAXBException    * @throwsTransformerFactoryConfigurationError    * @throws TransformerException    * @throws XPathExpressionException    * @author zhutulang    * @version 1.0    */   @Test   public void test3() throws MalformedURLException, JAXBException,TransformerFactoryConfigurationError, TransformerException,XPathExpressionException{      //1.创建服务      URL url = new URL(wsdlUrl);      QName qName = new QName(namespaceUrl, "MyServiceInterImplService");      Service service = Service.create(url, qName);           //2.创建dispatch （通过源数据方式传递）      Dispatch<Source> dispatch = service.createDispatch(new QName(namespaceUrl,            "MyServiceInterImplPort"), Source.class, Service.Mode.PAYLOAD);           //3.根据一个User对象创建相应的xml      User user = new User("Lucy", "123456", 26);      JAXBContext ctx = JAXBContext.newInstance(User.class);      Marshaller mar = ctx.createMarshaller();      mar.setProperty(Marshaller.JAXB_FRAGMENT, true);      StringWriter writer = new StringWriter();      mar.marshal(user, writer);           //4、封装相应的part addUser      String payload = "<nn:addUser xmlns:nn=\""+namespaceUrl+"\">"+writer.toString()+"</nn:addUser>";      System.out.println(payload);      StreamSource rs = new StreamSource(new StringReader(payload));           //5.通过dispa传递payload      Source response = dispatch.invoke(rs);           //6.将source转换为DOM      Transformer transformer = TransformerFactory.newInstance().newTransformer();      DOMResult result = new DOMResult();      transformer.transform(response, result);           //7.处理相应的消息      XPath xPath = XPathFactory.newInstance().newXPath();      NodeList nl = (NodeList) xPath.evaluate("//user", result.getNode(), XPathConstants.NODESET);      User ru = (User) ctx.createUnmarshaller().unmarshal(nl.item(0));      System.out.println(ru);   }
