简单的webservice开发例子
Axis支持三种web service的部署和开发，分别为：
1、Dynamic Invocation Interface ( DII)
2、Stubs方式
3、Dynamic Proxy方式
二、编写DII(Dynamic Invocation Interface )方式web服务
1.编写服务端程序HelloClient
public class HelloClient
{
public String getName(String name)
{
return 'hello '+name;
}
}
2、将源码拷贝到Axis_HOME下，重命名为 HelloClient.jws
3、访问连接http://localhost:8080/Axis/HelloClient.jws?wsdl，页面显示Axis自动生成的wsdl
4、编写访问服务的客户端 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(endpoint));
String ret = (String) call.invoke(new Object[]
{'zhangsan'});
System.out.println('return value is ' + ret);
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
}
三、编写Dynamic Proxy方式访问服务
1、编写部署服务端程序，同上边DII方式，本次仍使用上边部署的HelloClient
2、编写代理接口
public interface HelloClientInterface
extends java.rmi.Remote
{
public String getName(String name)
throws java.rmi.RemoteException;
}
3、编写并执行客户端程序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(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、编写wsdd发布web服务，编写stub client访问web服务
1、编写服务端程序server,SayHello.java，编译server.SayHello.java
package server;
public class SayHello
{
public String getName(String name)
{
return 'hello '+name;
}
}
2.编写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、编写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='server.SayHello'/>
<parameter name='allowedMethods'
value='*'/>
</service>
</deployment>
3、将编译后的文件拷贝到Axis_HOME/WEB-INF/classes下，如：D:\tomcat\webapps\Axis\WEB-INF\classes
4、发布服务：
java org.apache.Axis.client.AdminClient deploy.wsdd
5、生成client stub文件
a:方式1
将SayHello.java拷贝到Axis_HOME/下，重命名为SayHello.jws，
执行下面的命令生存client stub
java org.apache.Axis.wsdl.WSDL2Java
-p client http://localhost:8080
/Axis/services/SayHello.jws?wsdl
b:方式2
执行如下命令生成SayHello.wsdl
java org.apache.Axis.wsdl.Java2WSDL
-oSayHello.wsdl -lhttp://localhost:8080
/Axis/services/SayHello -nsayhello server.SayHello
执行如下命令生成client stub
java org.apache.Axis.wsdl.WSDL2Java
SayHello.wsdl -p client
生成的stub client文件列表为：
1.SayHello.java
2.SayHelloService.java。
3.SayHelloServiceLocator.java
4.SayHelloSoapBindingStub.java
6、编写客户端程序，编译并执行
public class SayHelloClient
{
public static void main(String[] args)
{
try
{
SayHelloService service = new client.
SayHelloServiceLocator();
client.SayHello_PortType
client = service.getSayHello();
String retValue=client.getName('zhangsan');
System.out.println(retValue);
}
catch (Exception e)
{
System.err.println
('Execution failed. Exception: ' + e);
}
}
}
