CXF全接触(十) --- 异步调用代码演示

参考：http://www.javaeye.com/topic/305642

如下图所示建立工程：

代码如下：

AsyncCallBackClient.java

AsyncPollingClient.java

Server.java

package server;import org.apache.cxf.jaxws.JaxWsServerFactoryBean;import test.HelloWorldImpl;public class Server {public static void main(String[] args) {JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();factory.setServiceClass(HelloWorldImpl.class);factory.setAddress("http://localhost:8080/HelloWorld");factory.create();}}

HelloWorldImpl.java

package test;import javax.jws.WebService;@WebServicepublic class HelloWorldImpl implements IHelloWorld {public String sayHello(String name) {try{Thread.sleep(1000);}catch(Exception ex) {}System.out.println("sayHello is called by " + name);return "Hello " + name;}}

IHelloWorld.java

package test;import javax.jws.WebService;@WebServicepublic interface IHelloWorld {public String sayHello(String name);}
