CXF+Spring+Tomcat 案例

多系统（异构系统）进行交互时，一种良好的方式便是调用Web Service，本示例基于Apache组织的CXF

环境：
Eclipse
JDK6
Tomcat6
CXF2.6.1
Spring3

示例项目结构图：

IHelloService.java

package bing.server;

import javax.jws.WebService;

/**
 * <p>
 * WebService接口
 * </p>
 * 
 * @author IceWee
 * @date 2012-7-6
 * @version 1.0
 */
@WebService
public interface IHelloService {

    public String sayHello(String username);
    
}

HelloServiceImpl.java

package bing.server;

import javax.jws.WebService;

/**
 * <p>
 * WebService实现类
 * </p>
 * 
 * @author IceWee
 * @date 2012-7-6
 * @version 1.0
 */
@WebService(endpointInterface = "bing.server.IHelloService", serviceName = "HelloService")
public class HelloServiceImpl implements IHelloService {

    @Override
    public String sayHello(String username) {
        return "hello, " + username;
    }

}

HelloServiceClient.java

package bing.client;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import bing.server.IHelloService;

/**
 * <p>
 * WebService调用方-客户端
 * </p>
 * 
 * @author IceWee
 * @date 2012-7-6
 * @version 1.0
 */
public class HelloServiceClient {

    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");
        IHelloService helloService = (IHelloService) context.getBean("client");
        String response = helloService.sayHello("Peter");
        System.out.println(response);
    }

}
