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 6.0
2、到http://ws.apache.org/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SayHello
package 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.java
import javax.xml.namespace.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service Service service = new Service(); Call call = null; //创建call call = (Call) service.createCall(); //设置操作名 call.setOperationName(new QName(" http://localhost/webservice/SayHello.jws","getName")); //设置访问点 call.setTargetEndpointAddress(new java.net.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SayHello
2、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.java
package com.qdl.client; import java.net.URL; import javax.xml.namespace.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(new URL(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SayHello
package 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=" 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.Directory" value="./attachments"/> <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"/> <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>http://xml.apache.org/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"/> <handler type="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=" http://xml.apache.org/axis/wsdd/" xmlns:java=" http://xml.apache.org/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 stub
java org.apache.axis.wsdl.WSDL2Java -p com.qdl.client http://localhost/webservice/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/webservice/SayHello -nsayhello com.qdl.server.SayHello
执行如下命令生成client stub
java 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.java
2.SayHelloService.java。
3.SayHelloServiceLocator.java
4.SayHelloSoapBindingStub.java
把com包整体剪到src下编译
6、编写客户端程序，编译并执行
package com.qdl.client; public class SayHelloClient2 { public static void main(String[] args){ //访问定制发布的服务 try{ SayHelloService service = new SayHelloServiceLocator(); SayHello_PortType client = service.getSayHello(); String retValue = client.getName("zhangsan"); System.out.println("返回的信息是："+retValue); }catch (Exception e){ System.err.println("Execution failed. Exception: " + e); } } }
