Axis開發webservice三種方式

一、Axis開發方式

Axis支持三種web service的部署和開發，分別爲：

1、Dynamic Invocation Interface ( DII)

2、Stubs方式

3、Dynamic Proxy方式

二、編寫DII(Dynamic Invocation Interface )方式web服務

1.編寫服務端程序HelloClient

public class HelloClient
{
    public String getName(String name)
    {
        return "hello "+name;
    }
}

2、將源碼拷貝到Axis_HOME下，重命名爲 HelloClient.jws

3、訪問連接http://localhost:8080/Axis/HelloClient.jws?wsdl，頁面顯示Axis自動生成的wsdl

4、編寫訪問服務的客戶端 TestHelloClient.java

import org.apache.Axis.client.Call;
import org.apache.Axis.client.Service;
import javax.xml.namespace.QName;
import javax.xml.rpc.ServiceException;
import java.net.MalformedURLException;
import java.rmi.RemoteException;

public class SayHelloClient2
{
    public static void main(String[] args)
{
        try
  {
String endpoint =
"http://localhost:8080/Axis/HelloClient.jws";

Service service = new Service();
Call call = null;

call = (Call) service.createCall();

            call.setOperationName(new QName(
               "http://localhost:8080/Axis/HelloClient.jws",
      "getName"));
            call.setTargetEndpointAddress
   (new java.net.url(/blog/endpoint));

            String ret = (String) call.invoke(new Object[]
   {"zhangsan"});
            System.out.println("return value is " + ret);
        }
  catch (Exception ex)
  {
       ex.printStackTrace();
        }
    }
}

三、編寫Dynamic Proxy方式訪問服務

1、編寫部署服務端程序，同上邊DII方式，本次仍使用上邊部署的HelloClient

2、編寫代理接口

public interface HelloClientInterface
extends java.rmi.Remote
{
public String getName(String name)
throws java.rmi.RemoteException;
}

3、編寫並執行客戶端程序TestHelloClient.java

import javax.xml.rpc.Service;
import javax.xml.rpc.ServiceFactory;
import java.net.URL;
import javax.xml.namespace.QName;

public class TestHelloClient
{
    public static void main(String[] args)
{
        try
        {
            String wsdlUrl =
   "http://localhost:8080/Axis/HelloClient.jws?wsdl";
            String nameSpaceUri =
   "http://localhost:8080/Axis/HelloClient.jws";
            String serviceName = "HelloClientService";
            String portName = "HelloClient";

            ServiceFactory serviceFactory =
   ServiceFactory.newInstance();
            Service afService =
   serviceFactory.createService(new url(/blog/wsdlUrl),
         new QName(nameSpaceUri, serviceName));
            HelloClientInterface proxy = (HelloClientInterface)
        afService.getPort(new QName(
                    nameSpaceUri, portName),
     HelloClientInterface.class);
            System.out.println
   ("return value is "+proxy.getName("john") ) ;
        }catch(Exception ex)
        {
            ex.printStackTrace() ;
        }
    }
}

四、編寫wsdd發佈web服務，編寫stub client訪問web服務

1、編寫服務端程序server,SayHello.java，編譯server.SayHello.java

package server;
public class SayHello
{
    public String getName(String name)
    {
        return "hello "+name;
    }
}
2.編寫LogHandler.java
import org.apache.Axis.AxisFault;
import org.apache.Axis.Handler;
import org.apache.Axis.MessageContext;
import org.apache.Axis.handlers.BasicHandler;

import java.util.Date;

public class LogHandler
extends BasicHandler
{
public void invoke
(MessageContext msgContext)
throws AxisFault
    {
        /** Log an access each time
  we get invoked.
         */
        try {
            Handler serviceHandler
   = msgContext.getService();

            Integer numAccesses =
(Integer)serviceHandler.getOption("accesses");
            if (numAccesses == null)
                numAccesses = new Integer(0);
numAccesses = new Integer
(numAccesses.intValue() + 1);
Date date = new Date();
String result =
date + ": service " +
msgContext.getTargetService() +
" accessed " + numAccesses + " time(s).";
serviceHandler.setOption
("accesses", numAccesses);
System.out.println(result);
        } catch (Exception e)
  {
            throw AxisFault.makeFault(e);
        }
    }
}

3、編寫wsdd文件

deploy.wsdd
<deployment xmlns=
"http://xml.apache.org/Axis/wsdd/"
xmlns:java=
   "http://xml.apache.org/Axis/wsdd/providers/java">
   <handler name="print" type="java:LogHandler"/>
<service name="sayhello"
provider="java:RPC">
   <requestFlow>
     <handler type="print"/>
   </requestFlow>
<parameter name="className"
value="/blog/server.SayHello"/>
<parameter name="allowedMethods"
value="*"/>
</service>
</deployment>

3、將編譯後的文件拷貝到Axis_HOME/WEB-INF/classes下，如：D:/tomcat/webapps/Axis/WEB-INF/classes

4、發佈服務：

java org.apache.Axis.client.AdminClient deploy.wsdd

5、生成client stub文件

a:方式1

將SayHello.java拷貝到Axis_HOME/下，重命名爲SayHello.jws，

執行下面的命令生存client stub

java org.apache.Axis.wsdl.WSDL2Java
-p client http://localhost:8080
/Axis/services/SayHello.jws?wsdl

b:方式2

執行如下命令生成SayHello.wsdl

java org.apache.Axis.wsdl.Java2WSDL
-oSayHello.wsdl -lhttp://localhost:8080
/Axis/services/SayHello -nsayhello server.SayHello

執行如下命令生成client stub

java org.apache.Axis.wsdl.WSDL2Java
SayHello.wsdl -p client

生成的stub client文件列表爲：

1.SayHello.java

2.SayHelloService.java。

3.SayHelloServiceLocator.java

4.SayHelloSoapBindingStub.java

6、編寫客戶端程序，編譯並執行

public class SayHelloClient
{
    public static void main(String[] args)
{
        try
  {
    SayHelloService service = new client.
       SayHelloServiceLocator();
          client.SayHello_PortType
    client = service.getSayHello();
            String retvalue="/blog/client.getName(""zhangsan");
            System.out.println(retValue);
}
catch (Exception e)
{
System.err.println
("Execution failed. Exception: " + e);
        }
    }
}
