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***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

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.创建HelloWorld实现类

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

3.创建Server端测试类

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.创建Client端测试类

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.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 kongxx!的message。
