使用 interface + implement 的組合

WEB-INF/ws/MyWs.java

package ws;

import javax.jws.WebMethod;

import javax.jws.WebService;

import javax.jws.soap.SOAPBinding;

import javax.jws.soap.SOAPBinding.Style;

//Service Endpoint Interface

@WebService

@SOAPBinding(style = Style.RPC)

public interface MyWs{

@WebMethod String getHelloWorldAsString();

}

WEB-INF/ws/MyWsImpl.java

package ws;

import javax.jws.WebService;

//Service Implementation Bean

@WebService(endpointInterface = "ws.MyWs")

public class MyWsImpl implements MyWs{

@Override

public String getHelloWorldAsString() {

return "Hello World JAX-WS";

}

}

請在 WEB-INF/classes 編譯

[~/WEB-INF/classes]$ javac -cp . ws/MyWs.java

[~/WEB-INF/classes]$ javac -cp . ws/MyWsImpl.java

使用直接實作的方式

package ws;

import javax.jws.WebMethod;

import javax.jws.WebService;

 import javax.jws.soap.SOAPBinding;

import javax.jws.soap.SOAPBinding.Style;

//Service Implementation Bean

@WebService

@SOAPBinding(style = Style.RPC)

public class MyWs{

@WebMethod

public String getHelloWorldAsString() {

return "Hello World JAX-WS";

}

}

請在 WEB-INF/classes 編譯

[~/WEB-INF/classes]$ javac -cp . ws/MyWs.java

可以用瀏覽器

http ://serviceURI/services/MyWs

Client Side

用 tool 把需要的檔案生出來 (在此為 Linux 環境下)

wsimport -p wsClient -keep http : //serviceURI/services/MyWs?wsdl

這裡的 services/MyWs 與 server-side 的 web.xml 和 sun-jaxws.xml 配置有關

相關檔案指定以 package wsClient 的結構生成

WEB-INF/classes/wsClient/MyWs.java

package wsClient;

import javax.jws.WebMethod;

import javax.jws.WebResult;

import javax.jws.WebService;

import javax.jws.soap.SOAPBinding;

/**

 * This class was generated by the JAX-WS RI.

 * JAX-WS RI 2.1.6 in JDK 6

 * Generated source version: 2.1

 *

 */

@WebService(name = "MyWs", targetNamespace = "http://ws/")

@SOAPBinding(style = SOAPBinding.Style.RPC)

public interface MyWs {

/**

 *

 * @return

 *     returns java.lang.String

 */

@WebMethod

@WebResult(partName = "return")

public String getHelloWorldAsString();

}

WEB-INF/classes/wsClient/MyWsImplService.java

package wsClient;

import java.net.MalformedURLException;

import java.net.URL;

import java.util.logging.Logger;

import javax.xml.namespace.QName;

import javax.xml.ws.Service;

import javax.xml.ws.WebEndpoint;

import javax.xml.ws.WebServiceClient;

import javax.xml.ws.WebServiceFeature;

/**

 * This class was generated by the JAX-WS RI.

 * JAX-WS RI 2.1.6 in JDK 6

 * Generated source version: 2.1

 *

 */

@WebServiceClient(name = "MyWsImplService", targetNamespace = "http://ws/", wsdlLocation = "http://serviceURI/services/MyWs?wsdl")

public class MyWsImplService    extends Service{

private final static URL MYWSIMPLSERVICE_WSDL_LOCATION;

private final static Logger logger = Logger.getLogger(wsClient.MyWsImplService.class.getName());

static {

URL url = null;

try {

URL baseUrl;

baseUrl = wsClient.MyWsImplService.class.getResource(".");

url = new URL(baseUrl, "http://serviceURI/services/MyWs?wsdl");

} catch (MalformedURLException e) {

logger.warning("Failed to create URL for the wsdl Location: 'http://serviceURI/services/MyWs?wsdl', retrying as a local file");

logger.warning(e.getMessage());

}

MYWSIMPLSERVICE_WSDL_LOCATION = url;

}

public MyWsImplService(URL wsdlLocation, QName serviceName) {

super(wsdlLocation, serviceName);

}

public MyWsImplService() {

super(MYWSIMPLSERVICE_WSDL_LOCATION, new QName("http://ws/", "MyWsImplService"));

}

/**

 *

 * @return

 *     returns MyWs

 */

@WebEndpoint(name = "MyWsImplPort")

public MyWs getMyWsImplPort() {

return super.getPort(new QName("http://ws/", "MyWsImplPort"), MyWs.class);

}

/**

 *

 * @param features

 *     A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy.  Supported features not in the <code>features</code> parameter will have their default values.

 * @return

 *     returns MyWs

 */

@WebEndpoint(name = "MyWsImplPort")

public MyWs getMyWsImplPort(WebServiceFeature... features) {

return super.getPort(new QName("http://ws/", "MyWsImplPort"), MyWs.class, features);

}

}

我載了一個 testWS 的 servlet 叫用這個 service

import java.io.*;

import javax.servlet.*;

import javax.servlet.http.*;

import wsClient.*;

public class testWS extends HttpServlet{

PrintWriter out;

public void init(ServletConfig conf) throws ServletException{

super.init(conf);

}

public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException{

out = res.getWriter();

out.print(req.getParameter("doPost"));

}

public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

out = res.getWriter();out.print("doGet");

MyWsImplService myWsImplService = new MyWsImplService();

MyWs myWs = myWsImplService.getMyWsImplPort();

out.println(myWs.getHelloWorldAsString() + System.currentTimeMillis());

}

}

可以用瀏覽器確認執行結果

http://URI/servlet/testWS

後記:

在 server 端

如果提供服務的主體沒有 @SOAPBinding(style = Style.RPC) 的宣告

wsimport 預設會以 @SOAPBinding(style = Style.DOCUMENT) 的方式來生成相關檔案
