Axis开发Web Service实例

一、Axis安装 1、环境 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/网站下载Axis安装包

3、解压缩安装包，将Axis_UNZIP_PATH/Axis-version/webapps下的Axis包拷贝到TOMCAT_HOME/webapps/下，以下约定Axis_HOME为该TOMCAT_HOME/webapps/Axis目录

4、启动tomcat,访问http://localhost:8080/Axis 检查安装是否成功

5、以上步骤执行成功，可以开发webservice例子了

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 HelloClientInterfaceextends 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.javaimport 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);        }    }}
