篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CXF+Spring+Eclipse简明示例相关的知识，希望对你有一定的参考价值。

Eclipse+CXF+Spring共同开发的示例，供大家赏鉴。

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，为了方便起见特将服务端和客户端写在同一个工程下，实际项目中是不可能的，但是客户端却依赖于服务端的Web Service接口，那么可以通过导出jar的方式。

环境：
Eclipse Mars.1 Release (4.5.1)
JDK 1.7.0_15
Tomcat 7
CXF 2.1.3

Spring3

如上图所示，全部依赖的第三方库都在lib中，下面贴出全部代码。

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);
    }

}
