Apache CXF实现Web Service（1）——不借助重量级Web容器和Spring实现一个纯的JAX-WS web service
废话少说，先在Eclipse中新建一个Java Project
（可以不是WTP的Dynamic Web Project）
选择Java Project
再看pom.xml
我们使用cxf 3.1.4版本，
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.cnblog.richaaaard.cxfstudy</groupId> <artifactId>cxf-test-standalone-ws-helloworld</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>cxf-test-standalone-ws-helloworld Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- <cxf.version>2.7.18</cxf.version> -->
<!-- 注意使用2.x.x版本的同学，下面例子中引入cxf-bundle-jaxrs是不必要的，因为jaxws启动一个服务需要类JaxWsServerFactoryBean在cxf-rt-frontend-jaxws.jar中-->

CXF Web Service （Annotation）实现，上代码
CXF支持两种方式发布一个web service，一种是Java Annotation（Bottom up），另外一种是先定义好wsdl和xsd schema然后通过工具生成（Top down），我们这里的例子先介绍Java Annotation。
首先我们需要定义一个web service接口类HelloWorld，并加上Annotation
package com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services; import javax.jws.WebMethod; import javax.jws.WebParam; import javax.jws.WebResult; import javax.jws.WebService; @WebService public interface HelloWorld { @WebMethod @WebResult String sayHi(@WebParam String text); } 在此我们先不介绍 @WebService、 @WebMethod、@WebResult还有@WebParam如何工作的。
然后我们需要用HelloWorldImpl来实现这个接口类，
package com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services; public class HelloWorldImpl implements HelloWorld { public String sayHi(String name) { String msg = "Hello " + name + "!"; return msg; } } 发布一个Web Service
我们先用一个最简单的方式，使用javax.xml.ws.Endpoint来发布
package com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.server; import javax.xml.ws.Endpoint; import com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services.HelloWorldImpl; public class SimpleServer { public static void main(String[] args) throws Exception { System.out.println("Starting Server"); HelloWorldImpl implementor = new HelloWorldImpl(); String address = "http://localhost:9000/ws/HelloWorld"; Endpoint.publish(address, implementor); } } 注意：这里的address路径是大小写敏感的，如果发布成"http://localhost:9000/ws/ helloWorld "，而客户端使用/HelloWorld会找不到服务。
直接Run As..-> Java Application
我们可以在Eclipse中看到一个jetty服务正常运行
Starting Server 128 [main] INFO org.apache.cxf.service.factory.ReflectionServiceFactoryBean - Creating Service {http://services.helloworld.ws.standalone.cxftest.richaaaard.cnblog.com/}HelloWorldImplService from class com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services.HelloWorld 487 [main] INFO org.apache.cxf.endpoint.ServerImpl - Setting the server's publish address to be http://localhost:9000/ws/HelloWorld 506 [main] INFO org.eclipse.jetty.server.Server - jetty-8.1.15.v20140411 554 [main] INFO org.eclipse.jetty.server.AbstractConnector - Started SelectChannelConnector@localhost:9000 此时，我们通过浏览器访问http://localhost:9000/ws/HelloWorld?WSDL
如何访问我们发布的这个服务呢？
我们利用jaxws中的JaxWsProxyFactoryBean来消费这个服务
package com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.client; import org.apache.cxf.interceptor.LoggingInInterceptor; import org.apache.cxf.interceptor.LoggingOutInterceptor; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; import com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services.HelloWorld; public class Client { public static void main(String[] args) { JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.getInInterceptors().add(new LoggingInInterceptor()); factory.getOutInterceptors().add(new LoggingOutInterceptor()); factory.setServiceClass(HelloWorld.class); factory.setAddress("http://localhost:9000/ws/HelloWorld"); HelloWorld helloworld = (HelloWorld) factory.create(); String reply = helloworld.sayHi("HI"); System.out.println("Server said: " + reply); System.exit(0); } } 同样右键选择Client.java，Run As.. ->Java Application，我们可以看到运行后台执行的日志最后成功返回“Server said: Hello HI!”
114 [main] INFO org.apache.cxf.service.factory.ReflectionServiceFactoryBean - Creating Service {http://services.helloworld.ws.standalone.cxftest.richaaaard.cnblog.com/}HelloWorldService from class com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services.HelloWorld 531 [main] INFO org.apache.cxf.services.HelloWorldService.HelloWorldPort.HelloWorld - Outbound Message --------------------------- ID: 1 Address: http://localhost:9000/ws/HelloWorld Encoding: UTF-8 Http-Method: POST Content-Type: text/xml Headers: {Accept=[*/*], SOAPAction=[""]} Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:sayHi xmlns:ns2="http://services.helloworld.ws.standalone.cxftest.richaaaard.cnblog.com/"><arg0>HI</arg0></ns2:sayHi></soap:Body></soap:Envelope> -------------------------------------- 748 [main] INFO org.apache.cxf.services.HelloWorldService.HelloWorldPort.HelloWorld - Inbound Message ---------------------------- ID: 1 Response-Code: 200 Encoding: UTF-8 Content-Type: text/xml;charset=UTF-8 Headers: {Content-Length=[258], content-type=[text/xml;charset=UTF-8], Server=[Jetty(8.1.15.v20140411)]} Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:sayHiResponse xmlns:ns2="http://services.helloworld.ws.standalone.cxftest.richaaaard.cnblog.com/"><return>Hello HI!</return></ns2:sayHiResponse></soap:Body></soap:Envelope> -------------------------------------- Server said: Hello HI! 上面Outbound Message和Inbound Message是我们加的两个Logging Interceptor输出的日志，关于Interceptor的原理和更多使用方式，会专题介绍。
这样就完成了一个Web Service的发布和消费
*服务端的扩展
除了用一个最简单的javax.xml.ws.Endpoint来发布CXF web service，我们还可以使用cxf-rt-frontend-jaxws.jar中的JaxWsServerFactoryBean来发布一个web service，它可以让我们更多的控制web service的行为，比如说加Logging Interceptor之类
package com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.server; import org.apache.cxf.interceptor.LoggingInInterceptor; import org.apache.cxf.interceptor.LoggingOutInterceptor; import org.apache.cxf.jaxws.JaxWsServerFactoryBean; import com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services.HelloWorld; import com.cnblog.richaaaard.cxftest.standalone.ws.helloworld.services.HelloWorldImpl; public class Server { public static void main(String[] args) throws Exception { JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean(); factory.setServiceClass(HelloWorld.class); HelloWorldImpl implementor = new HelloWorldImpl(); factory.setServiceBean(implementor); factory.getInInterceptors().add(new LoggingInInterceptor()); factory.getOutInterceptors().add(new LoggingOutInterceptor()); factory.setAddress("http://localhost:9000/ws/HelloWorld"); factory.create(); System.out.println("Server start..."); Thread.sleep(60 * 1000); System.out.println("Server exit..."); System.exit(0); } } 参考：
