WebService学习总结十使用Spring发布WebService并添加拦截器

来源：互联网发布：业务数据分析师要求编辑：程序博客网时间：2024/06/06 00:01

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> *  *  *  *  * * * * */@Overridepublic void handleMessage(SoapMessage msg) throws Fault {List<Header> headers=msg.getHeaders(); //创建Head//创建head里的元素，添加到headDocument 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.xsdhttp://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}@Overridepublic 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;}@Overridepublic String toString() {return "UserBean [id=" + id + ", name=" + name + "]";}}

SEI:

package ws.spring.server;import javax.jws.WebMethod;import javax.jws.WebService;@WebServicepublic interface UserWS {@WebMethodpublic UserBean getUserById(int id);}

SEIImpl

package ws.spring.server;import javax.jws.WebService;@WebServicepublic class UserWSImpl implements UserWS {public UserWSImpl(){System.out.println("初始化 UserWSImpl");}@Overridepublic UserBean getUserById(int id) {System.out.println("server getUserById:"+id);return new UserBean(1, "张三");}}

配置文件

<?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.xsdhttp://cxf.apache.org/jaxws http://cxf.apache.org/jaxws">      <!-- 引cxf的一些核心配置 -->   <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="userWS"      implementor="ws.spring.server.UserWSImpl"      address="/userws">     <jaxws:inInterceptors>     <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>     <bean class="ws.server.interceptor.MyServerInterceptor"></bean>     </jaxws:inInterceptors>    </jaxws:endpoint>     </beans>
