Axis开发Web Service实例（三种方式）
原文：http://blog.csdn.net/lusonglin3g/article/details/4587440
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SayHello.java
public class SayHello {
public String getName(String name) {
return "hello "+name;
}
}
2、将源码拷贝到Axis_HOME下，重命名为SayHello.jws
3、访问连接http://localhost:8080/axis/SayHello.jws?wsdl，页面显示Axis自动生成的wsdl
4、编写访问服务的客户端 SayHelloClient.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 SayHelloClient {
public static void main(String[] args) {
try {
String endpoint = "http://localhost:8080/axis/SayHello.jws";
Service service = new Service();
Call call = null;
call = (Call) service.createCall();
call.setOperationName(new QName("http://localhost:8080/axis/SayHello.jws",
"getName"));
call.setTargetEndpointAddress(new java.net.URL(endpoint));
String ret = (String) call.invoke(new Object[] {"someone's name"});
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/SayHello.jws?wsdl";
String nameSpaceUri = "http://localhost:8080/axis/SayHello.jws";
String serviceName = "SayHelloService";
String portName = "SayHello";
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("someone's name") ) ;
} 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SayHello.java，编译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
<?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">
<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SayHello.class和LogHandler.class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
方式一：jws即时自动部署
将SayHello.java拷贝到Axis_HOME/services目录下，重命名为SayHello.jws，执行下面的命令生成client stub
java org.apache.axis.wsdl.WSDL2Java -p client http://localhost:8080/axis/services/SayHello.jws?wsdl
注意：这种方式要求在你写的类中不能有具体包的信息，因为这正是Axis即时部署不支持的。由于在SayHello.java中特意加入了"package server;"，因此不能采用jws即时自动部署。
自动部署相当简单，但当你需要：
．映射自己的类型时
．不需要暴露源代码时
．需要自己的路径和包管理时
．对用户操作Web Services的事件进行相应时
就需要通过WSDD来自定义部署。
方式二：通过WSDD自定义部署
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
这时在当前目录下生成了client子目录，在client目录中生成的stub client文件列表为:
(1).SayHello_PortType.java
(2).SayHelloService.java
(3).SayHelloServiceLocator.java
(4).SayHelloSoapBindingStub.java
6、编写客户端程序，编译并执行
import client.*;
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("someone's name");
System.out.println(retValue);
} catch (Exception e) {
System.err.println("Execution failed. Exception: " + e);
}
}
}
您也可以编写server-config.wsdd，存放在Axis_HOME/WEB-INF目录下。
<?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:LogHandler"/> <service name="sayhello" provider="java:RPC"> <requestFlow> <handler type="print"/> </requestFlow> <parameter name="className" value="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>
