axis 实现webservice实例

一、Axis安装 1、环境 J2SE SDK 1.5 or 1.6: 我使用 1.6 Servlet Container: 我使用的Tomcat 6.02、到 /Axis/网站下载Axis安装包3、先在eclipse下新建web project为WebServiceDemo.在Tomcat的配置xml 配置上：<Context path="/webservice"docBase="D:\workspace\WebServiceDemo\WebRoot"/>.解压下载的axis安装包，将webapps\axis下的lib文件夹和web.xml文件拷到工程对应目录4、启动tomcat,访问http://localhost/webservice检查安装是否成功，我的端口设置为80，页面index.html自动跳转后出错，是因为没把类拷入，先不管。

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.新建包com.qdl.server,编写服务端程序SayHellopackage com.qdl.server;public class SayHello{public String getName(String name){return "hello "+name;}}2、将源码拷贝到WebRoot下，重命名为 SayHello.jws (注意不用拷上面的package ...行)3、访问连接http://localhost/webservice/SayHello.jws?wsdl，页面显示Axis 自动生成的wsdl，同时会在WEB-INF下创建jwsClasses文件夹，在此生成SayHello.class文件4、新建包com.qdl.client,编写访问服务的客户端 SayHelloClient.javaimport space.QName;import org.apache.axis.client.Call;import org.apache.axis.client.Service;public class SayHelloClient {public static void main(String[] args){//程序访问即时发布的服务try{//创建访问点String endpoint = "http://localhost/webservice/SayHello.jws";//创建serviceService service = new Service();Call call = null;//创建callcall = (Call) service.createCall();//设置操作名call.setOperationName(newQName("http://localhost/webservice/SayHello.jws","getName"));//设置访问点call.setTargetEndpointAddress(new .URL(endpoint));//调用服务，返回值String ret = (String) call.invoke(new Object[]{"zhangsan"});System.out.println("返回的信息是：" + 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SayHello2、新建包com.qdl.dao编写代理接口package com.qdl.dao;import java.rmi.Remote;public interface HelloClientInterface extends Remote {public String getName(String name) throws java.rmi.RemoteException; }3、编写并执行客户端程序TestHelloClient.javapackage com.qdl.client;import .URL;import space.QName;import javax.xml.rpc.ServiceFactory;import javax.xml.rpc.Service;import com.qdl.dao.HelloClientInterface;public class TestHelloClient {public static void main(String[] args) {try {String wsdlUrl ="http://localhost/webservice/SayHello.jws?wsdl";String nameSpaceUri ="http://localhost/webservice/SayHello.jws";//注意下面的serviceName和portName,//http://localhost/webservice/SayHello.jws?wsdl页面的xml最下端有String serviceName = "SayHelloService";String portName = "SayHello";ServiceFactory serviceFactory = ServiceFactory.newInstance();Service afService = serviceFactory.createService(newURL(wsdlUrl), new QName(nameSpaceUri, serviceName));HelloClientInterface proxy = (HelloClientInterface)afService.getPort(new QName(nameSpaceUri, portName), HelloClientInterface.class);System.out.println("返回信息是：" + proxy.getName("zhangsan"));} catch (Exception ex) {ex.printStackTrace();}}}四、编写wsdd发布web服务，编写stub client访问web服务(定制发布服务)1、编写服务端程序SayHellopackage com.qdl.server;public class SayHello{public String getName(String name){return "hello "+name;}}2.编写LogHandler.java(好像这个并没什么用)import java.util.Date;import org.apache.axis.AxisFault;import org.apache.axis.Handler;import org.apache.axis.MessageContext;import org.apache.axis.handlers.BasicHandler;public class LogHandler extends BasicHandler {public void invoke(MessageContext msgContext) throws AxisFault { 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、先在WEB-INF目录下编写server-config.wsdd文件：文件名server-config.wsdd:<?xml version="1.0" encoding="UTF-8"?><deployment xmlns="/axis/wsdd/"xmlns:java="/axis/wsdd/pr oviders/java"><globalConfiguration><parameter name="adminPassword" value="admin"/><parameter name="attachments.Directory" value="./attachments"/><parameter name="attachments.implementation"value="org.apache.axis.attachments.Attachmen tsImpl"/><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.LocalRe sponder"/><handler name="URLMapper"type="java:org.apache.axis.handlers.http.URLMapper "/><handler name="Authenticate"type="java:org.apache.axis.handlers.SimpleAuthenti cationHandler"/><service name="AdminService" provider="java:MSG"><parameter name="allowedMethods" value="AdminService"/><parameter name="enableRemoteAdmin" value="false"/><parameter name="className" value="org.apache.axis.utils.Admin"/><namespace>/axis/wsdd/</namespace></service><service name="Version" provider="java:RPC"><parameter name="allowedMethods" value="getVersion"/><parameter name="className" value="org.apache.axis.Version"/></service><transport name="http"><requestFlow><handler type="URLMapper"/><handlertype="java:org.apache.axis.handlers.http.HTTPAuthHandler"/></requestFlow></transport><transport name="local"><responseFlow><handler type="LocalResponder"/></responseFlow></transport></deployment>然后在WEB-INF下再编写deploy.wsdd文件：文件名deploy.wsdd<deployment xmlns="/axis/wsdd/"xmlns:java="/axis/wsdd/providers/java"><service name="MyService" provider="java:RPC"><parameter name="className" value="com.qdl.server.SayHello"/> <parameter name="allowedMethods" value="*"/></service></deployment>4、发布服务：java org.apache.axis.client.AdminClient -lhttp://地址:端口/context模块/services/AdminService deploy.wsdd这一命令主要是把deploy.wsdd的service配置到server-config.wsdd中,同时更新内存注意：上面命令的前提是要把axis的jar包配置到系统classpath环境变量中，否则报找不到类的错误5、生成client stub文件a:方式1(本人用得此种方式)将SayHello.java拷贝到WebRoot下(前面已经拷贝)，重命名为SayHello.jws，执行下面的命令生存client stubjava org.apache.axis.wsdl.WSDL2Java -p com.qdl.clienthttp://localhost/webservice/SayHello.jws?wsdlb:方式2执行如下命令生成SayHello.wsdljava org.apache.axis.wsdl.Java2WSDL -oSayHello.wsdl-lhttp://localhost/webservice/SayHello -nsayhellocom.qdl.server.SayHello执行如下命令生成client stubjava org.apache.axis.wsdl.WSDL2Java SayHello.wsdl -p com.qdl.client此时在文件夹WEB-INF下com.qdl.client下生成的stub client文件列表为：1.SayHello.java2.SayHelloService.java。
