webservice-demo

webservice开发步骤：

? 服务端开发

—定义服务接口

—实现服务接口

—通过CXF、xfire、axis等框架对外发布服务

?客户端调用

—通过有效途径（双方沟通、UDDI查找等）获取到Webservice的信息

—通过wsdl生成客户端（或者服务提供方提供对应的接口jar包）

—调用服务

?

service接口：

 
 

package?com.ws.jaxws.sayHello.service; ?
  
  
?
  
  
import?javax.jws.WebService; ?
  
  
import?javax.jws.soap.SOAPBinding; ?
  
  
import?javax.jws.soap.SOAPBinding.Style; ?
  
  
?
  
  
@WebService ?
  
  

//@SOAPBinding(style=Style.RPC) ?

  
  
public?interface?SayHelloService?{ ?
  
  
????public?String?sayHello(String?name); ?
  
  
} ?
 
 

service接口的实现类：

package?com.ws.jaxws.sayHello.service.impl; ?
  
  
?
  
  
import?javax.jws.WebService; ?
  
  
?
  
  
import?com.ws.jaxws.sayHello.service.SayHelloService; ?
  
  
?
  
  

@WebService(endpointInterface?=?"com.ws.jaxws.sayHello.service.SayHelloService",?name?=?"sayHelloService",?targetNamespace?=?"sayHello") ?

  
  
?
  
  
public?class?SayHelloServiceImpl?implements?SayHelloService?{ ?
  
  
?
  
  
????@Override ?
  
  
????public?String?sayHello(String?name)?{ ?
  
  
????????//?TODO?Auto-generated?method?stub ?
  
  

????????if("".equals(name)||name==null){ ?

  
  

????????????name="nobody"; ?

  
  
????????} ?
  
  
????????return?"hello?"+name; ?
  
  
????} ?
  
  
?
  
  
}?
 
 

客户端：

package?com.ws.jaxws.sayHello.server; ?
  
  
?
  
  
import?javax.xml.ws.Endpoint; ?
  
  
?
  
  
import?com.ws.jaxws.sayHello.service.impl.SayHelloServiceImpl; ?
  
  
?
  
  
public?class?SayHelloServer?{ ?
  
  
????public?static?void?main(String[]?args)?throws?Throwable{ ?
  
  
????????Endpoint.publish("http://localhost:8888/sayHelloService",?new?SayHelloServiceImpl()); ?
  
  
????????System.out.println("SayHelloService?is?running...."); ?
  
  
????????Thread.sleep(5?*?60?*?1000); ?
  
  
????????System.out.println("time?out...."); ?
  
  
????????System.exit(0); ?
  
  
????} ?
  
  
}?
 
 

运行客户端代码后在浏览器输入http://localhost:8888/sayHelloServoce?wsdl，即可生成wsdl代码，如下所示：

客户端调用：

package?com.ws.jaxws.sayHello.client; ?
  
  
?
  
  
import?java.net.MalformedURLException; ?
  
  
import?java.net.URL; ?
  
  
?
  
  
import?javax.xml.namespace.QName; ?
  
  
import?javax.xml.ws.Service; ?
  
  
?
  
  
import?com.ws.jaxws.sayHello.service.SayHelloService; ?
  
  
?
  
  
public?class?SayHelloClient?{ ?
  
  
????public?static?void?main(String[]?args)?throws?MalformedURLException?{ ?
  
  

????????String?url="http://localhost:8888/sayHelloService?wsdl"; ?

  
  

????????Service?service=Service.create(new?url),?new?QName("sayHello","SayHelloServiceImplService")); //获得webservice的信息 ?

  
  

????????SayHelloService?sayHelloService=service.getPort(SayHelloService.class);//return?a?proxy ?

  
  
????????System.out.println(sayHelloService.sayHello(null));//调用服务 ?
  
  
????????System.out.println(sayHelloService.sayHello("zhangsan")); ?
  
  
????} ?
  
  
}?
 
 

运行客户端代码，控制端输出： hello nobody hello zhangsan
