Java6自带的WebService

只需要在一个类上标注@WebService就可以了，当然这个类需要有服务方法，否则会报下面的错误：

Exception in thread "main" com.sun.xml.internal.ws.model.RuntimeModelerException: The web service defined by the class java6.webservice.HelloWorldService does not contain any valid WebMethods.

at com.sun.xml.internal.ws.spi.ProviderImpl.createAndPublishEndpoint(Unknown Source)

at javax.xml.ws.Endpoint.publish(Unknown Source)

at java6.webservice.HelloWorldService.main(HelloWorldService.java:13)

 

再使用Endpoint.publish()方法发布服务即可。

示例：

import javax.jws.WebService;

import javax.xml.ws.Endpoint;

 

@WebService

publicclass HelloWorldService {

 

public String sayHello(String name) {

return"hello" + name;

}

 

/**

* @param args

*/

publicstaticvoid main(String[] args) {

Endpoint.publish("http://localhost:8080/java6/webservice/HelloWorldService", new HelloWorldService());

}

 

}

这样服务端就写好了。

Endpoint.publish是一个后台线程，一旦发布了就会一直等待处理Web服务的请求。

在浏览器中输入http://localhost:8080/java6/webservice/HelloWorldService?wsdl，就可以看到发布的服务了。

客户端：

使用jdk的wsimport命令生成客户端代码：

编写我们调用服务的类：

 

import java6.webservice.client.*;

publicclass HelloWorldClient {

 

/**

* @param args

*/

publicstaticvoid main(String[] args) {

// TODO Auto-generated method stub

HelloWorldServiceService hwss = new HelloWorldServiceService();

java6.webservice.client.HelloWorldService hws = hwss.getHelloWorldServicePort();

String result = hws.sayHello("webservice");

System.out.println(result);

}

 

}

 

 

运行结果：hellowebservice。
