Apache的CXF現(xiàn)在幾乎成了Java領(lǐng)域構(gòu)建Web Service的***類庫，并且它也確實簡單易用，下面就通過幾篇系列文章做一下簡單介紹。

當(dāng)然首先想到的當(dāng)然還是那個Hello World示例。這個系列文章中用到的例子都是基于Maven構(gòu)建的工程，下面是我的pom.xml文件內(nèi)容

下面來看看HelloWorld的具體例子。

1.創(chuàng)建HelloWorld 接口類

package com.googlecode.garbagecan.cxfstudy.helloworld;  
 
import javax.jws.WebMethod;  
import javax.jws.WebParam;  
import javax.jws.WebResult;  
import javax.jws.WebService;  
 
@WebService 
public interface HelloWorld {  
    @WebMethod 
    @WebResult String sayHi(@WebParam String text);  
} 

2.創(chuàng)建HelloWorld實現(xiàn)類

package com.googlecode.garbagecan.cxfstudy.helloworld;  
 
public class HelloWorldImpl implements HelloWorld {  
 
    public String sayHi(String name) {  
        String msg = "Hello " + name + "!";  
        return msg;  
    }  
} 

3.創(chuàng)建Server端測試類

package com.googlecode.garbagecan.cxfstudy.helloworld;  
 
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;  
 
// http://localhost:9000/HelloWorld?wsdl  
public class Server {  
    public static void main(String[] args) throws Exception {  
        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();  
        factory.setServiceClass(HelloWorldImpl.class);  
          
        factory.setAddress("http://localhost:9000/ws/HelloWorld");  
        factory.create();  
 
        System.out.println("Server start...");  
        Thread.sleep(60 * 1000);  
        System.out.println("Server exit...");  
        System.exit(0);  
    }  
}  

4.創(chuàng)建Client端測試類

package com.googlecode.garbagecan.cxfstudy.helloworld;  
 
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;  
 
public class Client {  
    public static void main(String[] args) {  
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();  
        factory.setServiceClass(HelloWorld.class);  
        factory.setAddress("http://localhost:9000/ws/HelloWorld");  
        HelloWorld helloworld = (HelloWorld) factory.create();  
        System.out.println(helloworld.sayHi("kongxx"));  
        System.exit(0);  
    }  
} 

5.測試

首先運行Server類來啟動Web Service服務(wù)，然后訪問http://localhost:9000/ws/HelloWorld?wsdl地址來確定web service啟動正確。

運行Client測試類，會在命令行輸出Hello kongxx!的message。
