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;

/**?*//**

?*?
?*/
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="???

??
????<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"?/>???
??

????????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>???
??????????<!--?日志拦截器?-->??????
??????????<bean?src="//img.reader8.com/uploadfile/jiaocheng/2014015/1438/201401140038527562.gif">??????????<!--?自定义拦截器?-->?
??????????<bean?src="//img.reader8.com/uploadfile/jiaocheng/2014015/1438/201401140038527562.gif">??????????</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;
/**?*//**

?*
?*/

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
