apache cxf 编写web service接口样例程序

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，下面是个Hello World示例。例子是基于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.yeetrack.cxf;  

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.yeetrack.cxf;  

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.yeetrack.cxf;  

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.yeetrack.cxf;

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。
