Apache CXF实战之一 Hello World Web Service

Apache的CXF现在几乎成了Java领域构建Web Service的首选类库，并且它也确实简单易用，下面就通过几篇系列文章做一下简单介绍。

当然首先想到的当然还是那个Hello World示例。这个系列文章中用到的例子都是基于Maven构建的工程，下面是我的pom.xml文件内容

下面来看看HelloWorld的具体例子。

 

1.创建HelloWorld 接口类

 

[java] view plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.helloworld;  
2.   
3. import javax.jws.WebMethod;  
4. import javax.jws.WebParam;  
5. import javax.jws.WebResult;  
6. import javax.jws.WebService;  
7.   
8. @WebService  
9. public interface HelloWorld {  
10.     @WebMethod  
11.     @WebResult String sayHi(@WebParam String text);  
12. }  

2.创建HelloWorld实现类 

 

 

[java] view plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.helloworld;  
2.   
3. public class HelloWorldImpl implements HelloWorld {  
4.   
5.     public String sayHi(String name) {  
6.         String msg = "Hello " + name + "!";  
7.         return msg;  
8.     }  
9. }  

3.创建Server端测试类

 

 

[java] view plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.helloworld;  
2.   
3. import org.apache.cxf.jaxws.JaxWsServerFactoryBean;  
4.   
5. // http://localhost:9000/HelloWorld?wsdl  
6. public class Server {  
7.     public static void main(String[] args) throws Exception {  
8.         JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();  
9.         factory.setServiceClass(HelloWorldImpl.class);  
10.           
11.         factory.setAddress("http://localhost:9000/ws/HelloWorld");  
12.         factory.create();  
13.   
14.         System.out.println("Server start...");  
15.         Thread.sleep(60 * 1000);  
16.         System.out.println("Server exit...");  
17.         System.exit(0);  
18.     }  
19. }  

4.创建Client端测试类

 

 

[java] view plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.helloworld;  
2.   
3. import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;  
4.   
5. public class Client {  
6.     public static void main(String[] args) {  
7.         JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();  
8.         factory.setServiceClass(HelloWorld.class);  
9.         factory.setAddress("http://localhost:9000/ws/HelloWorld");  
10.         HelloWorld helloworld = (HelloWorld) factory.create();  
11.         System.out.println(helloworld.sayHi("xx"));  
12.         System.exit(0);  
13.     }  
14. }  

5.测试

 

首先运行Server类来启动Web Service服务，然后访问http://localhost:9000/ws/HelloWorld?wsdl地址来确定web service启动正确。

运行Client测试类，会在命令行输出Hello xx!的message。
