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.model.RuntimeModeler.buildRuntimeModel(Unknown Source)     at com.sun.xml.internal.ws.server.EndpointFactory.createSEIModel(Unknown Source)     at com.sun.xml.internal.ws.server.EndpointFactory.createEndpoint(Unknown Source)     at com.sun.xml.internal.ws.api.server.WSEndpoint.create(Unknown Source)     at com.sun.xml.internal.ws.api.server.WSEndpoint.create(Unknown Source)     at com.sun.xml.internal.ws.transport.http.server.EndpointImpl.createEndpoint(Unknown Source)     at com.sun.xml.internal.ws.transport.http.server.EndpointImpl.publish(Unknown Source)     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。
