本文详细介绍了CXF的SimpleFrontend概念，与JAX-WS前端的区别，以及如何通过反射映射类到WSDL模型。并通过具体代码展示了如何实现HelloService接口和服务实现类HelloServiceImpl，并通过Apache CXF客户端调用服务。

关于CXF中的Simple Frontend 的官方网站如下：

http://cxf.apache.org/docs/simple-frontend.html

CXF includes a simple frontend which builds services from reflection. This is in contrast to the JAX-WS frontend which requires you to annotate your web service classes or create a WSDL first. The simple frontend will use reflection to intelligently map your classes to a WSDL model.

By default CXF uses the JAXB databinding. If you are interested in a databinding which does not require annotations, please see the documentation on the Aegis Databinding (2.0.x).

上面的意思如下：

CXF的包括一个简单的前端建立在反射的基础上的服务。这是在对比了JAX - WS的前端，需要你来注释的web服务类或创建一个WSDL。简单的前端会使用反射类映射到上一个WSDL模型中。默认情况下使用了JAXB CXF的数据绑定。如果你是在一个数据绑定不感兴趣。

具体代码如下：

package com.easyway.cxf.service;

import java.util.List;

import com.easyway.cxf.model.User;
/**
* 服务的类
* @author longgangbai
*
*/
public interface HelloService {
/**
* @param name
* @return
*/
public String hello(String name);

/**
   * Advanced usecase of passing an Interface in. JAX-WS/JAXB does not
   * support interfaces directly. Special XmlAdapter classes need to
   * be written to handle them
   */
public String sayHi(User user);

public String[] getAllUseNames(List<User> userList);
}

package com.easyway.cxf.service;

import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;

import com.easyway.cxf.model.User;
/**
* 服务的实现类
* @author longgangbai
*
*/
public class HelloServiceImpl implements HelloService {

Map<Integer, User> users = new LinkedHashMap<Integer, User>();

public String hello(String username) {
return "Hello " + username;
}

public String sayHi(User user) {
         users.put(users.size() + 1, user);
         return "Hello " + user.getUsername();
}
public String[] getAllUseNames(List<User> userList) {
  String[] userListArr=new String[userList.size()];
  for (int i=0;i<userList.size();i++) {
   userListArr[i]=userList.get(i).getUsername();
  }
  return userListArr;
}

}

package com.easyway.cxf.test.client;

import org.apache.cxf.frontend.ClientProxyFactoryBean;

import com.easyway.cxf.service.HelloService;
import com.easyway.cxf.test.server.ApacheCFXServer;
/**
*
*
* @author longgangbai
*
*/
public class ApacheCFXClient {
public static void main(String[] args) {
  ClientProxyFactoryBean factory = new ClientProxyFactoryBean();
     factory.setServiceClass(HelloService.class);
     factory.setAddress(ApacheCFXServer.WS_ADDRESS);
     HelloService client = (HelloService) factory.create();
     System.out.println("Invoke sayHi()....");
     System.out.println(client.hello(System.getProperty("user.name")));

}
}

package com.easyway.cxf.test.server;

import org.apache.cxf.frontend.ServerFactoryBean;

import com.easyway.cxf.service.HelloService;
import com.easyway.cxf.service.HelloServiceImpl;

public class ApacheCFXServer {
public static final String WS_ADDRESS="http://localhost:8080/cxf/services/helloService";
public static void main(String[] args) {
HelloServiceImpl helloWorldImpl = new HelloServiceImpl();
// Create our Server
ServerFactoryBean svrFactory = new ServerFactoryBean();
svrFactory.setServiceClass(HelloService.class);
svrFactory.setAddress(WS_ADDRESS);
svrFactory.setServiceBean(helloWorldImpl);
svrFactory.create();
}
}
