另外有例子给出的slf4j是slf4j-jdk14 (http://mvnrepository.com/artifact/org.slf4j/slf4j-jdk14)的版本，如果用jdk5以上的同学可以将其替换成slf4j-simple实现。


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);
