2, SOAP消息的创建

  1>前面的一个简单WebService  服务

package com.yangw.soap.service;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

//说明该接口是服务接口,可以指定我们自己的命名空间
@WebServicepublic interface IMyService {

    /**
     * 使用注解指明返回值名,参数名
     */
     @WebResult(name="addResult")
     public int add(@WebParam(name="a")int a,@WebParam(name="b")int b);
}
package com.yangw.soap.service;

import javax.jws.WebService;

//说明该类是服务接口的实现类
@WebService(endpointInterface="com.yangw.soap.service.IMyService")
public class MyServiceImpl implements IMyService {

    @Override
    public int add(int a, int b) {
        System.out.println("a+b="+(a+b));
        return a+b;
    }

}
package com.yangw.soap.service;

import javax.xml.ws.Endpoint;

public class MyService {

    /**
     * @param args
     */
    public static void main(String[] args) {
        //发布服务
        Endpoint.publish("http://localhost:8899/ns", new MyServiceImpl());
    }

}

 2>SOAPMessage的创建

package com.yangw.soap.test;

import java.io.IOException;

import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPBodyElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;

import org.junit.Test;

public class TestSoap {

    /**
     * 自己创建soap协议
     */
    @Test
    public void test() {

        try {
            //1,创建消息工厂
            MessageFactory factory=MessageFactory.newInstance();
            //2,根据消息工厂创建soap消息
            SOAPMessage msg=factory.createMessage();
            //3,创建SOAPPart
            SOAPPart part=msg.getSOAPPart();
            //4,获取soapEnvelope
            SOAPEnvelope envelope=part.getEnvelope();
            //5,通过SOAPEnvelope可以有效的获取相应的Header和Body等
            SOAPBody body=envelope.getBody();
            //6,根据QName创建相应的节点(QName就是一个带有命名空间的节点)
            QName qName=new QName("http://service.soap.yangw.com/",
                    "add", "ns"); //相当于<ns:add xmlns="http://service.soap.yangw.com/" />
            //7,将QName加入到body中
//            body.addBodyElement(qName).setValue("123123");
            /**
             * <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
             *     <SOAP-ENV:Header/>
             *     <SOAP-ENV:Body>
             *         <ns:add xmlns:ns="http://service.soap.yangw.com/">123123</ns:add>
             *     </SOAP-ENV:Body>
             * </SOAP-ENV:Envelope>
             */
            //如果使用下面注释住的这个方式,会将<>转换为&lt;&gt;
            //body.addBodyElement(qName).setValue("<a>11</a><b>22</b>");
            //加子元素
            SOAPBodyElement bodyEle=body.addBodyElement(qName);
            bodyEle.addChildElement("a").setValue("11");

             */
        } catch (SOAPException e) {

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

3, SOAPMessage的传递

    private String ns="http://service.soap.yangw.com/";
    private String wsdlUrl="http://localhost:8899/ns?wsdl";

    /**
     * Soap消息的传递
     */
    @Test
    public void test02() {

        try {
            //1,创建服务
            URL url=new URL(wsdlUrl);
            QName qName=new QName(ns,"MyServiceImplService");
            Service service=Service.create(url, qName);

            //2,创建Dispatch
            Dispatch<SOAPMessage> dispatch=service.createDispatch(new QName(ns,"MyServiceImplPort"),//(创建Port的时候指定名称空间)
                    SOAPMessage.class, Service.Mode.MESSAGE);

            //3, 创建SOAPMessage
             SOAPMessage msg=MessageFactory.newInstance().createMessage();
             SOAPEnvelope envelope=msg.getSOAPPart().getEnvelope();
             SOAPBody body=envelope.getBody();

             //4, 创建QName来指定消息中传递的数据
             QName eName=new QName(ns,"add", "nn"); //前缀必须指定,名字可以任意 <nn:add xmlns="XXX" />
             SOAPBodyElement bodyEle=body.addBodyElement(eName);
             bodyEle.addChildElement("a").setValue("22");
             bodyEle.addChildElement("b").setValue("33");

             msg.writeTo(System.out); //输出消息到控制台
             /**
              * <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
              *     <SOAP-ENV:Header/>
              *     <SOAP-ENV:Body>
              *         <nn:add xmlns:nn="http://service.soap.yangw.com/">
              *             <a>22</a>
              *             <b>33</b>
              *         </nn:add>
              *     </SOAP-ENV:Body>
              * </SOAP-ENV:Envelope>
              */
             System.out.println("\n invoke ...");
             //5, 通过Dispatch传递消息
             SOAPMessage  resMsg= dispatch.invoke(msg);
             resMsg.writeTo(System.out);
             /**
              * <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
              *     <S:Header/>
              *     <S:Body>
              *         <ns2:addResponse xmlns:ns2="http://service.soap.yangw.com/">
              *             <addResult>55</addResult>
              *         </ns2:addResponse>
              *     </S:Body>
              * </S:Envelope>
              */
             //6, 将响应的消息转换为DOM对象
             Document doc=resMsg.getSOAPPart().getEnvelope().getBody().extractContentAsDocument();
             String str=doc.getElementsByTagName("addResult").item(0).getTextContent();
             System.out.println("\n"+str);
        } catch (SOAPException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

4, 基于PayLoad的方式传递SOAP消息,其实是附件的形式  下面实例是传递了一个自定义User对象 它可以传递字符串

package com.yangw.soap.service;

import java.util.Date;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class User {

    private String userName;
    private String password;
    private int age;
    private Date birthday;

    public User() {
        super();
    }
    public User(String userName, String password, int age, Date birthday) {
        super();
        this.userName = userName;
        this.password = password;
        this.age = age;
        this.birthday = birthday;
    }

    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public Date getBirthday() {
        return birthday;
    }
    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

}
package com.yangw.soap.service;

import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

//说明该接口是服务接口
@WebService
public interface IMyService {

    /**
     * 使用注解指明返回值名,参数名
     */
     @WebResult(name="addResult")
     public int add(@WebParam(name="a")int a,@WebParam(name="b")int b);

     //返回对象是什么类型就写什么值,不区分单个对象还是List
     @WebResult(name="user")
     public User addUser(@WebParam(name="user")User user);
     @WebResult(name="user")
     public User login(@WebParam(name="username")String username,@WebParam(name="password")String password);

     @WebResult(name="user")
     public List<User> list();

}
package com.yangw.soap.service;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import javax.jws.WebService;

//说明该类是服务接口的实现类
@WebService(endpointInterface="com.yangw.soap.service.IMyService")
public class MyServiceImpl implements IMyService {

    private static List<User> users=new ArrayList<User>();
    static{
        users.add(new User("yangw","123456",12,new Date()));
        users.add(new User("awei","123456",25,new Date()));
    }

    @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;
    }

    @Override
    public User login(String username, String password) {
        for(User user:users){
            if(user.getUserName().equals(username)&&user.getPassword().equals(password)){
                return user;
            }
        }
        return null;
    }

    @Override
    public List<User> list() {
        return users;
    }

}

  真正的处理消息的组成,发送和接收

    /**
     * Soap消息的传递,PAYLOAD方式可以传字符串的.
     */
    @Test
    public void test03() {

        try {
            //1,创建服务
            URL url=new URL(wsdlUrl);
            QName qName=new QName(ns,"MyServiceImplService");
            Service service=Service.create(url, qName);

            //2,创建Dispatch ,通过Source的方式传递
            Dispatch<Source> dispatch=service.createDispatch(new QName(ns,"MyServiceImplPort"),
                    Source.class, Service.Mode.PAYLOAD);

            //3, 根据用户对象创建相应的xml(编排)
            User user=new User("ahuang","123321",23,new Date());
            JAXBContext ctx=JAXBContext.newInstance(User.class);
            Marshaller mar=ctx.createMarshaller();
                //去掉文档头和尾
            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='"+ns+"'>"+writer.toString()+"</nn:addUser>";
            System.out.println(payLoad);

            //5,通过Dispatch传递 payLoad
            Source response=dispatch.invoke(new StreamSource(new StringReader(payLoad)));

            //6, 将Source转换为DOM操作,使用Transform对象
            Transformer tran=TransformerFactory.newInstance().newTransformer();
            DOMResult result=new DOMResult();
            tran.transform(response, result);

            //7,处理响应信息
            XPath xpath=XPathFactory.newInstance().newXPath();
            NodeList nl=(NodeList) xpath.evaluate("//user", result.getNode(),XPathConstants.NODESET);
                //反编排
            User u=(User) ctx.createUnmarshaller().unmarshal(nl.item(0));
            System.out.println(u.getUserName());

        } catch (IOException e) {
            e.printStackTrace();
        } catch (JAXBException e) {
            e.printStackTrace();
        } catch (TransformerConfigurationException e) {
            e.printStackTrace();
        } catch (TransformerFactoryConfigurationError e) {
            e.printStackTrace();
        } catch (TransformerException e) {
            e.printStackTrace();
        } catch (XPathExpressionException e) {
            e.printStackTrace();
        }
    }

5, list方法测试

package com.yangw.soap.service;

import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

//说明该接口是服务接口
@WebService
public interface IMyService {

    /**
     * 使用注解指明返回值名,参数名
     */
     @WebResult(name="addResult")
     public int add(@WebParam(name="a")int a,@WebParam(name="b")int b);

     //返回对象是什么类型就写什么值,不区分单个对象还是List
     @WebResult(name="user")
     public User addUser(@WebParam(name="user")User user);
     @WebResult(name="user")
     public User login(@WebParam(name="username")String username,@WebParam(name="password")String password);

     @WebResult(name="user")
     public List<User> list1();

     @WebResult(name="user")
     //设置header为true,让它以头信息的形式传递
     //这是显示的方式传递头部信息的方式
     public List<User> list2(@WebParam(name="authInfo",header=true)String authInfo);

}

  不带参数的list()方法

/**

     */
    @Test
    public void test04() {
