Spring與axis結合調用 WebService

在這篇文章中http://xace.iteye.com/blog/687457 ，
我們使用XFire發佈了Web Service，現在我們使用axis作爲客戶端，調用這個服務

因爲Web服務是平臺無關的，每個WSDL文件即能描述服務的全部信息，我們首先借助axis的WSDL2Java工具，將WSDL文件轉化爲java類
java -cp lib\axis.jar;lib\commons-logging.jar;lib\commons-discovery.jar;lib\jaxrpc.jar;lib\saaj.jar;lib\wsdl4j.jar org.apache.axis.wsdl.WSDL2Java -v -W -o src -p demo.webservice.client http://localhost:8888/BookService?wsdl
pause

生成的代碼在/demo/webservice/client目錄中

我們觀察http://localhost:8888/BookService?wsdl地址的WSDL文件，其中關鍵部分：

<wsdl:definitions targetNamespace="http://server.webservice.demo">

  <wsdl:service name="BookService">
    <wsdl:port name="BookServiceHttpPort" binding="tns:BookServiceHttpBinding">
      <wsdlsoap:address location="http://localhost:8888/BookService"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

  public static void main(String[] args) 
  throws ServiceException, MalformedURLException, RemoteException {
    // 客戶端調用代碼符合標準JAX-RPC接口，不會和具體底層框架綁定
    String wsdl = "http://localhost:8888/BookService?wsdl";
    String namespaceUri = "http://server.webservice.demo";
    String serviceName = "BookService";
    String portName = "BookServiceHttpPort";
    QName serviceQN = new QName(namespaceUri, serviceName);
    QName portQN = new QName(namespaceUri, portName);
    ServiceFactory factory = ServiceFactory.newInstance();
    Service srv = factory.createService(new URL(wsdl), serviceQN);
    BookServicePortType service = 
      (BookServicePortType) srv.getPort(portQN, BookServicePortType.class);
    SearchResponse search = service.search(new Search("j2ee"));
    System.out.println(Arrays.toString(search.getOut()));

    // 通過Spring JaxRpcPortProxyFactoryBean 取得
    ApplicationContext context =
      new ClassPathXmlApplicationContext("config.xml");
    MyService springService = (MyService) context.getBean("bookService");
    search = springService.search(new Search("j2ee"));
    System.out.println(Arrays.toString(search.getOut()));
  }

  <bean id="bookService"   
      class="org.springframework.remoting.jaxrpc.JaxRpcPortProxyFactoryBean">
    <!-- 
      BookServicePortType遠程調用方法都將拋出RemoteException，可以自定義一個具有
      相同方法簽名的接口，不拋出異常。這樣客戶端不知道自己調用的是Web服務，解耦
    -->
