首先使用Spring方式发布成功WebService,再在客户端和服务器端引入出拦截器和入拦截器，引入的方式是写在配置文件中的。


客户端：

自定义的拦截器

package ws.client.interceptor;

import java.util.List;

import javax.xml.namespace.QName;

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.xml.utils.DOMHelper;
import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class MyClientInterceptor extends AbstractPhaseInterceptor<SoapMessage> {
	//自定义的校验字段，姓名和密码
	private String name;
	private String pwd;
	
	public MyClientInterceptor(String name,String pwd) {
		super(Phase.PRE_PROTOCOL);//配置拦截时机，一定要有，准备协议化得时候拦截
		this.name=name;
		this.pwd=pwd;
	}

	//封装数据到消息里，格式如下
	/*    <Envelop>
	 * 			<head> //里面的标签可以有多个
	 * 				<atguigu>  //自定义标签，随意
	 * 					<name>zhangsan</name>
	 * 					<pwd>123123</pwd>
	 * 				</atguigu>
	 * 				<atguigu1>  //自定义标签，随意
	 * 					<name>zhangsan</name>
	 * 					<pwd>123123</pwd>
	 * 				</atguigu1>
	 * 			</head>
	 * 			<body>
	 * 				<sayHello>
	 * 					<arg0>BOB</arg0>
	 * 				</sayHello>
	 * 			</body>
	 * 	  </Envelop>
	 * 
	 * 
	 * 
	 * 
	 *
	 *
	 *
	 *
	 */
	@Override
	public void handleMessage(SoapMessage msg) throws Fault {
		List<Header> headers=msg.getHeaders(); //创建Head
		//创建head里的元素，添加到head
		Document document=DOMHelper.createDocument();
		Element atguigu=document.createElement("atguigu");
		
		Element name=document.createElement("name");
		name.setTextContent(this.name);
		atguigu.appendChild(name);
		
		Element pwd=document.createElement("pwd");
		pwd.setTextContent(this.pwd);
		atguigu.appendChild(pwd);
		
		headers.add(new Header(new QName("atguigu"), atguigu));//QName里的参数要和标签名一样
		System.out.println("client:handleMessage");
	}

}

wsimport生成的客户端代码：

GetUserById.java
GetUserByIdResponse.java
ObjectFactory.java
package-info.java
UserBean.java
UserWS.java
UserWSImplService.java


客户端的配置：

<?xml version="1.0" encoding="UTF-8"?>
<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/jaxws">
	<jaxws:client id="userClient" 
		serviceClass= "ws.spring.server.UserWS" 
		address= "http://localhost:8080/ws_spring_interceptor_server/userws">	
		<!-- 添加客户端出拦截器 -->
		<jaxws:outInterceptors>
			<bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
			<bean class="ws.client.interceptor.MyClientInterceptor">
				<constructor-arg name="name" value="zhangsan"/>
				<constructor-arg name="pwd" value="123"/>
			</bean>
		</jaxws:outInterceptors>
	</jaxws:client>
</beans>

客户端测试类： 

package ws.spring.server;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestClient {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(
				new String[]{"client-beans.xml"});
		UserWS userWS=(UserWS) context.getBean("userClient");
		UserBean userBean=userWS.getUserById(1);
		System.out.println("Client:"+userBean);
	}

}



服务器端：

自定义的拦截器：

package ws.server.interceptor;

import javax.xml.namespace.QName;

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.w3c.dom.Element;
/**
 * 检查用户名称和密码
 * @author
 *
 */
public class MyServerInterceptor extends AbstractPhaseInterceptor<SoapMessage> {

	public MyServerInterceptor() {
		super(Phase.PRE_PROTOCOL);
		// TODO Auto-generated constructor stub
	}

	@Override
	public void handleMessage(SoapMessage msg) throws Fault {
		// 读header里的数据
		Header header=msg.getHeader(new QName("atguigu"));//参数和客户端传的一样
		if(header!=null){
			Element atguigu=(Element) header.getObject();
			String name=atguigu.getElementsByTagName("name").item(0).getTextContent();
			String pwd=atguigu.getElementsByTagName("pwd").item(0).getTextContent();
			if(name.equals("zhangsan")&&pwd.equals("123")){
				System.out.println("server:check ok");
				return;
			}
		}
		//没通过校验,抛出异常
		System.out.println("没有通过校验");
		throw new Fault(new RuntimeException("用户名或密码不对"));
	}

}


bean:

package ws.spring.server;

public class UserBean {
	private int id;
	private String name;
	
	public UserBean(int id, String name) {
		super();
		this.id = id;
		this.name = name;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@Override
	public String toString() {
		return "UserBean [id=" + id + ", name=" + name + "]";
	}
	
}


SEI:

package ws.spring.server;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface UserWS {
	@WebMethod
	public UserBean getUserById(int id);
}


SEIImpl

package ws.spring.server;

import javax.jws.WebService;

@WebService
public class UserWSImpl implements UserWS {
	public UserWSImpl(){
		System.out.println("初始化 UserWSImpl");
	}
	@Override
	public UserBean getUserById(int id) {
		System.out.println("server getUserById:"+id);
		return new UserBean(1, "张三");
	
	}

}
