1， SOAPMessage结构图
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<>
//body.addBodyElement(qName).setValue("<a>11</a><b>22</b>");
//加子元素
SOAPBodyElement bodyEle=body.addBodyElement(qName);
bodyEle.addChildElement("a").setValue("11");
bodyEle.addChildElement("b").setValue("22");
//打印消息
msg.writeTo(System.out);
/**
* <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/">
* <a>11</a>
* <b>22</b>
* </ns:add>
* </SOAP-ENV:Body>
* </SOAP-ENV:Envelope>
*/
} catch (SOAPException e) {
e.printStackTrace();
} 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
/**
* Soap消息的传递 --测试 list()方法，不带参数的形式
*/
@Test
public void test04() {
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 (创建Port的时候指定名称空间)
Dispatch<SOAPMessage> dispatch=service.createDispatch(new QName(ns,"MyServiceImplPort"),
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,"list1", "nn"); //前缀必须指定，名字可以任意 <nn:add xmlns="XXX" />
body.addBodyElement(eName);
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:list xmlns:nn="http://service.soap.yangw.com/"/>
* </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);
System.out.println();
/**
*<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
* <S:Header/>
* <S:Body>
* <ns2:listResponse xmlns:ns2="http://service.soap.yangw.com/">
* <user>
* <age>12</age>
* <birthday>2014-03-03T14:21:02.468+08:00</birthday>
* <password>123456</password>
* <userName>yangw</userName>
* </user>
* <user>
* <age>25</age>
* <birthday>2014-03-03T14:21:02.468+08:00</birthday>
* <password>123456</password>
* <userName>awei</userName>
* </user>
* </ns2:listResponse>
* </S:Body>
*</S:Envelope>
*/
//6, 将响应的消息转换为DOM对象
Document doc=resMsg.getSOAPPart().getEnvelope().getBody().extractContentAsDocument();
NodeList nl=doc.getElementsByTagName("user");
JAXBContext ctx=JAXBContext.newInstance(User.class);
for(int i=0;i<nl.getLength();i++){
Node node=nl.item(i); //import org.w3c.dom.Node;
User user=(User) ctx.createUnmarshaller().unmarshal(node);
System.out.println(user.getUserName()+":"+user.getPassword());
}
} catch (SOAPException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JAXBException e) {
e.printStackTrace();
}
}
带参数的list()方法测试
/**
* Soap消息的传递 --测试 list(String)方法，带参数的形式，一般都是把参数放到头信息中作验证
*/
@Test
public void test05() {
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 (创建Port的时候指定名称空间)
Dispatch<SOAPMessage> dispatch=service.createDispatch(new QName(ns,"MyServiceImplPort"),
SOAPMessage.class, Service.Mode.MESSAGE);
//3, 创建SOAPMessage
SOAPMessage msg=MessageFactory.newInstance().createMessage();
SOAPEnvelope envelope=msg.getSOAPPart().getEnvelope();
//3.2 头信息的处理
SOAPHeader header=envelope.getHeader();
if(header==null)
header=envelope.addHeader();
QName hName=new QName(ns,"authInfo", "nn");
header.addHeaderElement(hName).setValue("aabbcc");
SOAPBody body=envelope.getBody();
//4, 创建QName来指定消息中传递的数据
QName eName=new QName(ns,"list2", "nn"); //前缀必须指定，名字可以任意 <nn:add xmlns="XXX" />
body.addBodyElement(eName);
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>
* <nn:authInfo xmlns:nn="http://service.soap.yangw.com/">aabbcc</nn:authInfo>
* </SOAP-ENV:Header>
* <SOAP-ENV:Body>
* <nn:list2 xmlns:nn="http://service.soap.yangw.com/"/>
* </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);
System.out.println();
/**
*<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
* <S:Header/>
* <S:Body>
* <ns2:listResponse xmlns:ns2="http://service.soap.yangw.com/">
* <user>
* <age>12</age>
* <birthday>2014-03-03T14:21:02.468+08:00</birthday>
* <password>123456</password>
* <userName>yangw</userName>
* </user>
* <user>
* <age>25</age>
* <birthday>2014-03-03T14:21:02.468+08:00</birthday>
* <password>123456</password>
* <userName>awei</userName>
* </user>
* </ns2:listResponse>
* </S:Body>
*</S:Envelope>
*/
//6, 将响应的消息转换为DOM对象
Document doc=resMsg.getSOAPPart().getEnvelope().getBody().extractContentAsDocument();
NodeList nl=doc.getElementsByTagName("user");
JAXBContext ctx=JAXBContext.newInstance(User.class);
for(int i=0;i<nl.getLength();i++){
Node node=nl.item(i); //import org.w3c.dom.Node;
User user=(User) ctx.createUnmarshaller().unmarshal(node);
System.out.println(user.getUserName()+":"+user.getPassword());
}
} catch (SOAPException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JAXBException e) {
e.printStackTrace();
}
}
上面头消息的处理是显示消息的处理，用wsimport导出之后，可以看到会“自动生成一个List对象”
接口上的名称空间应该与实现类上的名称空间一致.
