2019獨角獸企業重金招聘Python工程師標準>>>

多系統（異構系統）進行交互時，一種良好的方式便是調用Web Service，本示例基于Apache組織的CXF，為了方便起見特將服務端和客戶端寫在同一個工程下，實際項目中是不可能的，但是客戶端卻依賴于服務 端的Web Service接口，那么可以通過導出jar的方式。

環境：
MyEclipse10
JDK6
Tomcat7
CXF2.5
Spring3

示例項目結構圖：


如上圖所示，全部依賴的第三方庫都在lib中，下面貼出全部代碼。
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實現類
* </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調用方-客戶端

* @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);
??? }

}

所有項目都已配置完成，可以發布到Tomcat了，在瀏覽器中輸入：http://localhost:8080/CXFDemo/ws，返回如圖：


從上圖中可以看到我們對外發布的WebService接口，點擊藍色超鏈接，返回如圖：

到此，證明我們的Web Service已經發布成功，可以進行調用測試了。運行HelloServiceClient，返回如圖：
