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。
