前言：常用的web service有两种形式，SOAP和RESTful。这里先说SOAP的实现步骤，RESTful的形式后面再说
一 建项目，导jar包
（1）项目结构
（2）在eclipse中新建一个动态web项目“CXFDemo”，并导入cxf中的jar包（路径：/WEB-INF/lib/）。当然，可以去官网下载，也可以直接使用我用过的jar包，链接：http://pan.baidu.com/s/1pKyelAV
（3）配置web.xml：
<?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" version="3.0"> <display-name>CXFDemo</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/classes/service-beans.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <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>/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
二 web service服务端类
（1）接口CXFService.java：
package cn.zifangsky;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
@WebService
public interface CXFService {
@WebMethod
public String sayHello(@WebParam(name="name") String name);
}说明：
@WebService：标记表示该接口是一个WebService服务
@WebMethod：标记表示WebService中的方法
@WebParam(name=”paramName”)表示方法中的参数，name属性限制了参数的名称，若没有指定该属性，参数将会被重命名
（2）具体的实现类CXFServiceImpl.java：
package cn.zifangsky.impl;
import cn.zifangsky.CXFService;
public class CXFServiceImpl implements CXFService {
public String sayHello(String name) {
return "Hello," + name + "\n" + Test.getExtraMessage();
}
}注：Test.java类：
package cn.zifangsky.impl;
public class Test {
public static String getExtraMessage(){
return "测试";
}
}（3）配置service-beans.xml：
<?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" xmlns:soap="http://cxf.apache.org/bindings/soap" 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"> <bean id="outLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor" /> <bean id="loggingFeature" class="org.apache.cxf.feature.LoggingFeature" /> <bean id="inLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor" /> <jaxws:server id="sayHelloServices" serviceClass="cn.zifangsky.CXFService" address="/soap/sayHello" > <jaxws:serviceBean> <bean class="cn.zifangsky.impl.CXFServiceImpl" /> </jaxws:serviceBean> <jaxws:outInterceptors> <ref bean="outLoggingInterceptor" /> </jaxws:outInterceptors> <jaxws:inInterceptors> <ref bean="inLoggingInterceptor" /> </jaxws:inInterceptors> <jaxws:features> <ref bean="loggingFeature" /> <wsa:addressing xmlns:wsa="http://cxf.apache.org/ws/addressing" /> </jaxws:features> </jaxws:server> </beans>
说明：
i）3个bean配置的是日志，在这里把日志相关的配置删掉也不影响web service服务的正常使用
ii）address指的是发布后这个服务的路径问题，比如说我这里就是：http://localhost:8080/CXFDemo/soap/sayHello
（4）测试
发布这个项目到tomcat，运行之后的效果如下：
点击那个链接，可以发现sayHello这个服务的地址是：http://localhost:8080/CXFDemo/soap/sayHello?wsdl
到此，这个web service的服务端已经配置完成
三 web service客户端配置
服务端提供服务，而客户端使用服务端提供的服务，因此客户端只需要调用服务端提供的服务就可以了
（1）客户端的项目结构：
（2）同样是新建一个动态web工程，然后引入cxf的jar包，同时需要把服务端的CXFService接口打包成一个jar包，然后导入到客户端的lib中，链接：http://pan.baidu.com/s/1eQVWups
（3）客户端测试类ClientDemo.java：
package cn.zifangsky.client;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import cn.zifangsky.CXFService;
public class ClientDemo {
public static void main(String args[]){
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"client-beans.xml"});
CXFService clientHello = (CXFService) context.getBean("clientHello");
String response = clientHello.sayHello("javaee");
context.close();
System.out.println("Response: " + response);
System.exit(0);
}
}（4）客户端配置文件client-beans.xml：
<?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.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> <bean id="outLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor" /> <bean id="loggingFeature" class="org.apache.cxf.feature.LoggingFeature" /> <bean id="inLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor" /> <jaxws:client id="clientHello" serviceClass="cn.zifangsky.CXFService" address="http://localhost:8080/CXFDemo/soap/sayHello?wsdl"> <jaxws:inInterceptors> <ref bean="inLoggingInterceptor" /> </jaxws:inInterceptors> <jaxws:outInterceptors> <ref bean="outLoggingInterceptor" /> </jaxws:outInterceptors> <jaxws:features> <ref bean="loggingFeature" /> <wsa:addressing xmlns:wsa="http://cxf.apache.org/ws/addressing" /> </jaxws:features> </jaxws:client> </beans>
说明：
这里的address需要填写服务的wsdl绝对地址，因此这里就是：http://localhost:8080/CXFDemo/soap/sayHello?wsdl
（5）测试
直接使用“Java Application”运行ClientDemo，输出如下：

Response: Hello,javaee
测试可以发现，最后成功输出了
Response: Hello,javaee 测试
因为我们在客户端中只引用了CXFService.java这个接口，但是却输出了预期的内容，说明客户端的确是调用了服务端的服务并成功返回信息的
