java WebService例子

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HelloClientpublic 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>4、将编译后的文件拷贝到Axis_HOME/WEB-INF/classes下，如：D:\tomcat\webapps\Axis\WEB-INF\classes 5、发布服务： java org.apache.Axis.client.AdminClient deploy.wsdd 6、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);
???????? }
???? }
}您也可以写server-config.wsdd
<?xml version="1.0" encoding="UTF-8"?>
<deployment xmlns="http://xml.apache.org/axis/wsdd/"
???????? xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<globalConfiguration>? ?? <parameter name="adminPassword" value="admin"/>?
?? <parameter name="attachments.implementation"
?????????? value="org.apache.axis.attachments.AttachmentsImpl"/>?
?? <parameter name="sendXsiTypes" value="true"/>?
?? <parameter name="sendMultiRefs" value="true"/>?
?? <parameter name="sendXMLDeclaration" value="true"/>?
?? <parameter name="axis.sendMinimizedElements" value="true"/>
??
?? <requestFlow>??
??? <handler type="java:org.apache.axis.handlers.JWSHandler">???
???? <parameter name="scope" value="session"/>??
??? </handler>??
??
??? <handler type="java:org.apache.axis.handlers.JWSHandler">???
???? <parameter name="scope" value="request"/>???
???? <parameter name="extension" value=".jwr"/>??
??? </handler>?
??
?? </requestFlow>
?
</globalConfiguration>
<handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/>
<handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/>
<handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/>??
?? <handler name="print" type="java:stub.LogHandler"/>
?
?? <service name="sayhello" provider="java:RPC">
??? <requestFlow>
????? <handler type="print"/>
??? </requestFlow>
?? <parameter name="className"??? value="stub.server.SayHello"/>?
?? <parameter name="allowedMethods"?? value="*"/>?
</service><transport name="http">?
?? <requestFlow>??
??? <handler type="URLMapper"/>??
??? <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/>?
?? </requestFlow>
</transport>
<transport name="local">?
?? <responseFlow>??
??? <handler type="LocalResponder"/>?
?? </responseFlow>
</transport>
</deployment>
这个更好用些
