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>
