首先在服务器和客户端都导入CXF和Spring相关的jar包

服务器端实现：

实体类：

public class Order {    private int id;    private String name;    private double price;    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;    }    public double getPrice() {        return price;    }    public void setPrice(double price) {        this.price = price;    }    public Order(int id, String name, double price) {        super();        this.id = id;        this.name = name;        this.price = price;    }    public Order() {        super();    }    @Override    public String toString() {        return "Order [id=" + id + ", name=" + name + ", price=" + price + "]";    }}

WS接口

@WebServicepublic interface OrderWS {    @WebMethod    public Order getOrderById(int id);}

WS实现类

@WebServicepublic class OrderWSImpl implements OrderWS {    public OrderWSImpl() {        System.out.println("OrderWSImpl()");    }    @Override    public Order getOrderById(int id) {        System.out.println("Server getOrderById()"+id);        return new Order(id,"飞机",1000000);    }}

自定义检查用户拦截器

package com.lin.ws.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;//检查用户拦截器public class CherkUserInterceptor extends AbstractPhaseInterceptor<SoapMessage> {    public CherkUserInterceptor() {        super(Phase.PRE_PROTOCOL);        System.out.println("CherkUserInterceptor()...");    }    /*    <Envelope>        <head>            <sea>                <name>jack</name>                <password>123</password>            <sea>        </head>        <Body>            <sayHello>                <arg0>KOK</arg0>            </sayHello>        </Body>    </Envelope>  */    @Override    public void handleMessage(SoapMessage message) throws Fault {        Header header= message.getHeader(new QName("sea"));        if(header!=null){            Element seaEle=(Element) header.getObject();            String name=seaEle.getElementsByTagName("name").item(0).getTextContent();            String password=seaEle.getElementsByTagName("password").item(0).getTextContent();            if("jack".equals(name)&&"123".equals(password)){                System.out.println("Server 通过拦截器...");                return;            }           }        //不能通过        System.out.println("Server 没有通过拦截器...");        throw new Fault(new RuntimeException("请求需要一个正确的用户名和密码"));    }}

bean.xml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/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" />    <jaxws:endpoint      id="orderWS"      implementor="com.cxf_spring.ws.OrderWSImpl"      address="/orderws">        <jaxws:inInterceptors>            <bean class="com.lin.ws.interceptor.CherkUserInterceptor"></bean>        </jaxws:inInterceptors>     </jaxws:endpoint></beans>

web.xml添加CXF框架和Spring配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">  <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:beans.xml</param-value>   </context-param>   <listener>      <listener-class>         org.springframework.web.context.ContextLoaderListener      </listener-class>   </listener>   <!--     所有请求都会经过CXF框架    -->   <servlet>      <servlet-name>CXFServlet</servlet-name>      <servlet-class>         org.apache.cxf.transport.servlet.CXFServlet      </servlet-class>      <load-on-startup>1</load-on-startup>   </servlet>   <servlet-mapping>      <servlet-name>CXFServlet</servlet-name>      <url-pattern>/*</url-pattern>   </servlet-mapping></web-app>

客户端实现：
新建一个web工程
创建一个

<?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/schemas/jaxws.xsd">    <jaxws:client id="orderClient"         serviceClass="com.cxf_spring.ws.OrderWS"         address="http://localhost:8080/WS_cxf_spring/orderws" >        <jaxws:outInterceptors>            <bean class="com.lin.ws.interceptor.AddUserInterceptor">                <constructor-arg name="name" value="jack"/>                <constructor-arg name="password" value="123"/>            </bean>        </jaxws:outInterceptors>    </jaxws:client></beans>

cmd进入客户端的src目录下，运用wsimport -keep http://localhost:8080/WS_cxf_spring/orderws 生成客户端代码
这里写图片描述

客户端拦截器：

package com.lin.ws.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.helpers.DOMUtils;import org.apache.cxf.interceptor.Fault;import org.apache.cxf.phase.AbstractPhaseInterceptor;import org.apache.cxf.phase.Phase;import org.w3c.dom.Document;import org.w3c.dom.Element;//自定义拦截器public class AddUserInterceptor extends AbstractPhaseInterceptor<SoapMessage> {    private String name;    private String password;    public AddUserInterceptor(String name,String password) {        super(Phase.PRE_PROTOCOL);//准备协议化时拦截        this.name=name;        this.password=password;        System.out.println("AddUserInterceptor()....");    }    /*        <Envelope>            <head>                <sea>                    <name>jack</name>                    <password>123</password>                <sea>            </head>            <Body>                <sayHello>                    <arg0>KOK</arg0>                </sayHello>            </Body>        </Envelope>      */    @SuppressWarnings("deprecation")    @Override    public void handleMessage(SoapMessage message) throws Fault {        /*         <sea>            <name>jack</name>            <password>123</password>        <sea>         * */        List<Header> headers=message.getHeaders();        Document document=DOMUtils.createDocument();        Element rootEle=document.createElement("sea");        Element nameEle=document.createElement("name");        System.out.println(name);        nameEle.setTextContent(name);        rootEle.appendChild(nameEle);        Element passwordEle=document.createElement("password");        System.out.println(password);        passwordEle.setTextContent(password);        rootEle.appendChild(passwordEle);        headers.add(new Header(new QName("sea"), rootEle));        System.out.println("Client handleMessage()....");    }}

编写测试类

import org.springframework.context.support.ClassPathXmlApplicationContext;import com.cxf_spring.ws.Order;import com.cxf_spring.ws.OrderWS;public class ClientTest {    public static void main(String[] args) {         ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]  {"client-beans.xml"});         OrderWS client = (OrderWS) context. getBean("orderClient");         Order order=client.getOrderById(24);         System.out.println(order);    }}

运行结果：
