Apache CXF实现的SOAP形式的webservices
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：

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";
}
}

<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);
}
}

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

测试
可以发现，最后成功输出了

2
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
