一、Axis安裝 1、環(huán)境 J2SE SDK 1.3 or 1.4: 我使用 1.4.2 Servlet Container: 我使用的Tomcat 5.0
2、到 http://ws.apache.org/Axis/網(wǎng)站下載Axis安裝包
3、解壓縮安裝包，將Axis_UNZIP_PATH\Axis-version\webapps下的Axis包拷貝到TOMCAT_HOME\webapps\下，以下約定Axis_HOME為該TOMCAT_HOME\webapps\Axis目錄
4、啟動tomcat,訪問http://localhost:8080/Axis 檢查安裝是否成功
5、以上步驟執(zhí)行成功，可以開發(fā)webservice例子了
Axis支持三種web service的部署和開發(fā)，分別為：
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(wù)
1.編寫服務(wù)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，重命名為 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(wù)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(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(wù)
1、編寫部署服務(wù)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、編寫并執(zhí)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(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(fā)布web服務(wù)，編寫stub client訪問web服務(wù)
1、編寫服務(wù)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="server.SayHello"/>
<parameter name="allowedMethods"
value="*"/>
</service>
</deployment> |
3、將編譯后的文件拷貝到Axis_HOME/WEB-INF/classes下，如：D:\tomcat\webapps\Axis\WEB-INF\classes
4、發(fā)布服務(wù)：
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，重命名為SayHello.jws，
執(zhí)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(zhí)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(zhí)行如下命令生成client stub
java org.apache.Axis.wsdl.WSDL2Java
SayHello.wsdl -p client |
生成的stub client文件列表為：
1.SayHello.java
2.SayHelloService.java。
3.SayHelloServiceLocator.java
4.SayHelloSoapBindingStub.java
6、編寫客戶端程序，編譯并執(zhí)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);
}
}
} |
