CXF 2.0 学习笔记-3 SOAP Header

基于CXF2.0前2个学习笔记，对原先服务端与客户端进行修改，实现在SOAP Header里面添加自定义的数据进行认证

在做之前，先要理解如下的信息
拦截器(Interceptor)简单说明
Interceptor是CXF架构中一个很有特色的模式。你可以在不对核心模块进行修改的情况下，动态添加很多功能。这对于CXF这个以处理消息为中心的服务框架来说是非常有用的，CXF通过在Interceptor中对消息进行特殊处理，实现了很多重要功能模块，例如：日志记录，Soap消息处理，消息的压缩处。简单的说，可以在收到请求后，还未进行业务处理前，进行处理。或者在请求包发送前，进行报文的处理。
几个的API的介绍
Interceptor

定义两个方法，一个处理消息 handleMessage，一个是处理错误 handleFault。

InterceptorChain
单个的Interceptor功能有限，CXF要实现一个SOAP消息处理，需要将许许多多的Interceptor组合在一起使用。因此设计了 InterceptorChain，在我看了InterceptorChain就像是一个Interceptor的小队长。小队长有调配安置Interceptor的权力（add，remove），也有控制消息处理的权力（doInterceptor，pause，resume，reset，abort），同时也有交付错误处理的权力（ {get|set}FaultObserver）。更有意思的是为灵活控制Interceptor的处理消息顺序（doInterceptStartingAt，doInterceptorStartingAfter），这也是InterceptorChain比较难理解的地方。
Fault
定义了CXF中的错误消息。
InterceptorProvider
　　这里定义了Interceptor的后备保障部队。我们可以在InterceptorProvider中设置In，Out，InFault，OutFault 后备小分队，添加我们所希望添加的Interceptor。而InterceptorChain会根据这些后备小分队，组建自己的小分队实例，完成具体的作战功能任务。
AbstractAttributedInterceptorProvider
   InterceptorProvider实现的抽象类，由于这个类来继承了HashMap，我们可以像这个类中存储一些属性信息。
AbstractBasicInterceptorProvider
   与AbstractAttributedInterceptorProvider不同，这个Interceptor只是简单实现了InterceptorProvider的功能，并不提供对其属性存储的扩展。
Message
   由于Interceptor是针对Message来进行处理的，当你打开Message这个类文件时，你会发现在Message中定义了很多常量，同时你还可以从Message中获取到很多与Message操作相关的信息。可以获取设置的对象有InterceptorChain Exchange Destination，还有获取设置Content的泛型接口，是不是感觉Message和Bus差不多，都成了大杂货铺，一切与消息处理相关的信息都可以放在Message中。

理解了Interceptor功能，下面的修改就很简单了

服务端修改
1.新建一个拦截器(Interceptor)

package hs.cxf.soapHeader;

import javax.xml.soap.SOAPException;

import javax.xml.soap.SOAPHeader;

import javax.xml.soap.SOAPMessage;

import org.apache.cxf.binding.soap.SoapMessage;

import org.apache.cxf.binding.soap.saaj.SAAJInInterceptor;

import org.apache.cxf.interceptor.Fault;

import org.apache.cxf.phase.AbstractPhaseInterceptor;

import org.apache.cxf.phase.Phase;

import org.w3c.dom.NodeList;

/**

* @Title:获取soap头信息

* @Description:

* @Copyright:

* @author zz

* @version 1.00.000

public class ReadSoapHeader extends AbstractPhaseInterceptor < SoapMessage > {

private SAAJInInterceptor saa = new SAAJInInterceptor();

public ReadSoapHeader() {

super(Phase.PRE_PROTOCOL);

getAfter().add(SAAJInInterceptor.class.getName());

}

public void handleMessage(SoapMessage message) throws Fault {

SOAPMessage mess = message.getContent(SOAPMessage.class);

if (mess == null) {

saa.handleMessage(message);

mess = message.getContent(SOAPMessage.class);

}

SOAPHeader head = null;

try {

head = mess.getSOAPHeader();

} catch (SOAPException e) {

e.printStackTrace();

}

if (head == null) {

return;

}

try {

//读取自定义的节点

NodeList nodes = head.getElementsByTagName("tns:spId");

NodeList nodepass = head.getElementsByTagName("tns:spPassword");

//获取节点值，简单认证

if (nodes.item(0).getTextContent().equals("wdw")) {

if (nodepass.item(0).getTextContent().equals("wdwsb")) {

System.out.println("认证成功");

}

} else {

SOAPException soapExc = new SOAPException("认证错误");

throw new Fault(soapExc);

}

} catch (Exception e) {

SOAPException soapExc = new SOAPException("认证错误");

throw new Fault(soapExc);

}

2.配置文件中新增拦截器配置

< beans xmlns ="http://www.springframework.org/schema/beans"

xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"

xmlns:jaxws ="http://cxf.apache.org/jaxws"

xsi:schemaLocation ="

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd" >

< import resource ="classpath:META-INF/cxf/cxf.xml" />

< import resource ="classpath:META-INF/cxf/cxf-extension-soap.xml" />

< import resource ="classpath:META-INF/cxf/cxf-servlet.xml" />

< bean id ="jaxWsServiceFactoryBean"

class ="org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean" >

< property name ="wrapped" value ="true" />

< property name ="dataBinding" ref ="aegisBean" />

</ bean >

< bean id ="aegisBean"

class ="org.apache.cxf.aegis.databinding.AegisDatabinding" />

< jaxws:endpoint id ="CollectiveServices"

implementor ="hs.cxf.server.WebServiceSampleImpl" address ="/HelloWorld" >

< jaxws:inInterceptors >

</ jaxws:inInterceptors >

< jaxws:serviceFactory >

< ref bean ="jaxWsServiceFactoryBean" />

</ jaxws:serviceFactory >

</ jaxws:endpoint >

</ beans >

服务端的配置就告一段落了，接下来是客户端的修改
客户端
1.同样新增一个Interceptor

package hs.cxf.client.SoapHeader;

import java.util.List;

import javax.xml.namespace.QName;

import org.apache.cxf.binding.soap.SoapHeader;

import org.apache.cxf.binding.soap.SoapMessage;

import org.apache.cxf.binding.soap.interceptor.AbstractSoapInterceptor;

import org.apache.cxf.headers.Header;

import org.apache.cxf.helpers.DOMUtils;

import org.apache.cxf.interceptor.Fault;

import org.apache.cxf.phase.Phase;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

/**

* @Title:在发送消息前，封装Soap Header 信息

* @Description:

* @Copyright:

* @author zz

* @version 1.00.000

public class AddSoapHeader extends AbstractSoapInterceptor {

private static String nameURI="http://127.0.0.1:8080/cxfTest/ws/HelloWorld";

public AddSoapHeader(){

super(Phase.WRITE);

}

public void handleMessage(SoapMessage message) throws Fault {

String spPassword="wdwsb";

String spName="wdw";

QName qname=new QName("RequestSOAPHeader");

Document doc=DOMUtils.createDocument();

//自定义节点

Element spId=doc.createElement("tns:spId");

spId.setTextContent(spName);

//自定义节点

Element spPass=doc.createElement("tns:spPassword");

spPass.setTextContent(spPassword);

Element root=doc.createElementNS(nameURI, "tns:RequestSOAPHeader");

root.appendChild(spId);

root.appendChild(spPass);

SoapHeader head=new SoapHeader(qname,root);

List<Header> headers=message.getHeaders();

headers.add(head);

System.out.println(">>>>>添加header<<<<<<<");

}

2.客户端调用程序修改

package hs.cxf.client;

import hs.cxf.client.SoapHeader.AddSoapHeader;

import java.util.ArrayList;

import javax.xml.bind.JAXBElement;

import javax.xml.namespace.QName;

import org.apache.cxf.endpoint.Client;

import org.apache.cxf.frontend.ClientProxy;

import org.apache.cxf.interceptor.Interceptor;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import org.apache.cxf.transport.http.HTTPConduit;

import org.apache.cxf.transports.http.configuration.HTTPClientPolicy;

/**

* @Title:

* @author zz

* @version 1.00.000

public class TestClient {

/**

@SuppressWarnings("unchecked")

public void testSend1() {

try {

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

ArrayList<Interceptor> list = new ArrayList<Interceptor>();

// 添加soap header

list.add(new AddSoapHeader());

// 添加soap消息日志打印

list.add(new org.apache.cxf.interceptor.LoggingOutInterceptor());

factory.setOutInterceptors(list);

factory.setServiceClass(WebServiceSample.class);

factory.setAddress("http://127.0.0.1:8080/cxfTest/ws/HelloWorld");

Object obj = factory.create();

System.out.println(obj == null ? "NULL" : obj.getClass().getName());

if (obj != null) {

WebServiceSample ws = (WebServiceSample) obj;

String str = ws.say("test");

System.out.println(str);

str = ws.say("1111");

System.out.println(str);

User u = new User();

JAXBElement<String> je = new JAXBElement<String>(new QName(

"http://bean.cxf.hs", "name"), String.class, "张三");

u.setName(je);

str = ws.sayUserName(u);

System.out.println(str);

// 通过对象来交互

ReqBean req = new ReqBean();

req.setExp(new JAXBElement<String>(new QName(

"http://bean.cxf.hs", "exp"), String.class,

"<exp>111<exp>"));

req.setSeqId(new JAXBElement<String>(new QName(

"http://bean.cxf.hs", "seqId"), String.class,

"12345678"));

RespBean resp = ws.action(req);

System.out.println("resp_id:" + resp.getRespId().getValue());

System.out.println("resp_exp:" + resp.getExp().getValue());

}

} catch (Exception ex) {

ex.printStackTrace();

}

/**

* 测试2

@SuppressWarnings("unchecked")

public void testSend2() {

String webServiceUrl = "http://127.0.0.1:8080/cxfTest/ws/HelloWorld";

String webServiceConTimeout = "60000";

String webServiceRevTimeout = "60000";

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

ArrayList<Interceptor> list = new ArrayList<Interceptor>();

// 添加soap header 信息

list.add(new AddSoapHeader());

// 添加soap消息日志打印

list.add(new org.apache.cxf.interceptor.LoggingOutInterceptor());

factory.setOutInterceptors(list);

factory.setServiceClass(WebServiceSample.class);

factory.setAddress(webServiceUrl);

WebServiceSample service = (WebServiceSample) factory.create();

//超时时间设置

Client clientP = ClientProxy.getClient(service);

HTTPConduit http = (HTTPConduit) clientP.getConduit();

HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();

httpClientPolicy.setConnectionTimeout(Integer

.valueOf(webServiceConTimeout));

httpClientPolicy.setReceiveTimeout(Integer

.valueOf(webServiceRevTimeout));

httpClientPolicy.setAllowChunking(false);

http.setClient(httpClientPolicy);

// 通过对象来交互

ReqBean req = new ReqBean();

req.setExp(new JAXBElement<String>(new QName(

"http://bean.cxf.hs", "exp"), String.class,

"<exp>111<exp>"));

req.setSeqId(new JAXBElement<String>(new QName(

"http://bean.cxf.hs", "seqId"), String.class,

"12345678"));

System.out.println(">>>>>>发送消息<<<<<<<<<");

RespBean resp = service.action(req);

System.out.println("resp_id:" + resp.getRespId().getValue());

System.out.println("resp_exp:" + resp.getExp().getValue());

}

/**

* @param args

public static void main(String[] args) {

TestClient tc = new TestClient();

tc.testSend1();

System.out.println(">>>>>>>>>>>>2<<<<<<<<<<<<<");

tc.testSend2();

System.out.println(">>>>>>>>>>>>END<<<<<<<<<<<<<");

}
