webservice 入门笔记三通过payload发送消息

新建一个User类：

packagecom.zhutulang.soap;
 
importjavax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public 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

    * @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);
   }
