CXF 增添拦截器+整合Spring

1.自定义拦截器

package com.cxf.interceptor;

import java.util.List;
import javax.xml.soap.SOAPException;
import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.apache.log4j.Logger;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

//AbstractPhaseInterceptor可以指定拦截器在那个阶段起作用
public class UserInterceptor extends AbstractPhaseInterceptor<SoapMessage> {

	Logger logger=Logger.getLogger(UserInterceptor.class);
	
	//显示调用父类的有参数的构造器就不会在隐示调用父类无参构造器
	public UserInterceptor() {
		super(Phase.PRE_INVOKE);//在调用之前拦截soap消息
	}

	@Override//message就是被拦截到的消息
	public void handleMessage(SoapMessage msg) throws Fault {
		//获取所有的头元素
		List<Header> headers=msg.getHeaders();
		if(headers==null || headers.size()==0){
			throw new Fault(new SOAPException("缺少Head 元素"));
		}
		//获取第一个头元素(w3c.dom.Element)
		Header firstHead= headers.get(0);
		Element element= (Element) firstHead.getObject();
		
		NodeList nameList= element.getElementsByTagName("userName");
		NodeList passWordList= element.getElementsByTagName("passWord");
		
		if(nameList.getLength()!=1 || passWordList.getLength()!=1){
			throw new Fault(new SOAPException("用户名密码格式有问题"));
		}
		
//		获取用户名密码
		String userName=nameList.item(0).getTextContent();
		String passWord=passWordList.item(0).getTextContent();
		
		logger.info(userName+":"+passWord);
		
		if(! userName.equals("rain") ||  ! passWord.equals("rain"))
			throw new Fault(new IllegalArgumentException("用户名密错误"));
		
		
	}

}

2.Web.Xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
	<display-name></display-name>

<!-- Spring配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/config/context/*.xml</param-value>
	</context-param>
<!-- Spring监听 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

<!-- CXFServlet 的访问地址-->
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/WebService/*</url-pattern>
	</servlet-mapping>


	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

3.Spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:jaxws="http://cxf.apache.org/jaxws" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.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" />

<!-- Service -->
	<bean id="UserServiceImpl" class="com.cxf.service.impl.UserServiceImp"></bean>
<!-- WebService -->
	<bean id="UserServiceWs" class="com.cxf.ws.impl.UserServiceWs">
		<property name="userService" ref="UserServiceImpl"></property>
	</bean>
<!-- 	拦截器 -->
	<bean id="userInterceptor" class="com.cxf.interceptor.UserInterceptor"/>

<!-- 发布的地址，实现的接口，实现类 ，拦截器-->
	
	<jaxws:server id="userManager" address="/userManager" serviceClass="com.cxf.ws.IUserServiceWs" >
		<jaxws:serviceBean>
			<ref bean="UserServiceWs"/>
		</jaxws:serviceBean>
		<jaxws:inInterceptors>
 			<ref bean="userInterceptor"/>
 		</jaxws:inInterceptors>
