WebService CXF学习（进阶篇3）：CXF整合Spring框架

 通过前面两节的讲解，相信你对CXF框架开始有一些认识了。在当今项目开发中，Spring框架基上都用到过，那么它怎么与CXF结合呢，这就是我们这一间要讲的内容。好了，闲话少说。
    首先，在前面基础上再导入几个spring要用到的几个.jar包：
               1、spring-asm.jar
               2、spring-beans.jar
               3、spring-context.jar
               4、spring-core.jar
               5、spring-expression.jar
               6、spring-aop.jar
               7、spring-web.jar
第一步：新建一个服务端web project,导入要用到的cxf和spring的.jar包，修改web.xml。配置如下

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"><!-- Spring 容器加载的配置文件 设置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:/applicationContext-server.xml</param-value></context-param>         <!-- Spring 配置 -->         <listener>                  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>         </listener>         <listener>                  <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>         </listener><!-- WebServices设置 --><servlet><servlet-name>CXFServices</servlet-name><servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class><load-on-startup>0</load-on-startup></servlet><servlet-mapping><servlet-name>CXFServices</servlet-name><url-pattern>/services/*</url-pattern></servlet-mapping>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

第二步：新建一个接口类和接口实现类

package com.ms.services;import java.util.List;import javax.jws.WebService;import com.ms.model.UserInfo;@WebServicepublic interface IHelloServices {public String sayHello(String name);public String sayHelloToAll(List<UserInfo> users);}

package com.ms.services.impl;import java.util.List;import javax.jws.WebService;import com.ms.model.UserInfo;import com.ms.services.IHelloServices;@WebService(endpointInterface="com.ms.services.IHelloServices")public class HelloServicesImpl implements IHelloServices {public String sayHello(String name) {return "Hello "+name+" .";}public String sayHelloToAll(List<UserInfo> users) {String hello = "hello ";for(UserInfo user:users){hello += user.getUserName()+" ,";}hello += " ,everybody.";return hello;}}

第三步：新建一个spring Bean的xml文件，配置CXF webservices的服务

<?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-3.0.xsd          http://cxf.apache.org/jaxws          http://cxf.apache.org/schemas/jaxws.xsd"><!-- Import apache CXF bean definition 固定--><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" /><!-- services接口配置 --><bean id="helloServicesBean" class="com.ms.services.impl.HelloServicesImpl" /><!-- CXF 配置WebServices的服务名及访问地址 --><jaxws:server id="helloServices" address="/HelloServices" serviceClass="com.ms.services.IHelloServices"><jaxws:serviceBean><ref bean="helloServicesBean"/></jaxws:serviceBean></jaxws:server></beans>

第四步：将工程部署到Tomcat中运行，在IE中输入"http://localhost:8090/CxfServer_Spring/services",测试服务是否发布成功
第五步：新建一个客户端web project,导入要用到的cxf和spring的.jar包
第六步：将服务端的接口类及JavaBean对象类copy到客户端工程中，且路径要与服务端路径一致
第七步：新建一个spring Bean的xml配置文件，配置CXF webservices的客户端

<?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-3.0.xsd          http://cxf.apache.org/jaxws          http://cxf.apache.org/schemas/jaxws.xsd"><!-- Import apache CXF bean definition --><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" /><!-- CXF webservices 客户端配置 --><jaxws:client id="helloClient" serviceClass="com.ms.services.IHelloServices" address="http://localhost:8090/CxfServer_Spring/services/HelloServices"></jaxws:client></beans>

第八步：新建一个测试类进行测试，代码如下

package com.test;import java.util.ArrayList;import java.util.List;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.ms.model.UserInfo;import com.ms.services.IHelloServices;public class Client {public static void main(String[] args) {invokeBySpring();}/** * 通过Spring测试webservices */public static void invokeBySpring(){ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");IHelloServices helloServices = context.getBean("helloClient",IHelloServices.class);List<UserInfo> users = new ArrayList<UserInfo>();users.add(new UserInfo("vicky",23));users.add(new UserInfo("caty",23));users.add(new UserInfo("ivy",23));users.add(new UserInfo("kelly",23));String helloAll = helloServices.sayHelloToAll(users);System.out.println(helloAll);}public static void invoke(){//创建WebService客户端代理工厂   JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();   //注册WebService接口   factory.setServiceClass(IHelloServices.class);   //设置WebService地址   factory.setAddress("http://localhost:8090/CxfServer_Spring/services/HelloServices");        IHelloServices helloServices = (IHelloServices)factory.create();   System.out.println("invoke helloServices webservice...");String hello = helloServices.sayHello("vicky");System.out.println(hello);}}
