axis 的施用
一、axis安装
1.环境
JDK1.5
Servlet Container: 我使用Tomcat 5.5
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
以下逐一讲述web service在axis上的部署和开发,设置classpath
set CLASSPATH=.;%AXIS_HOME%\lib\axis.jar;%AXIS_HOME%\lib\axis-ant.jar;%AXIS_HOME%\lib\commons-discovery-0.2.jar;%AXIS_HOME%\lib\commons-logging-1.0.4.jar;%AXIS_HOME%\lib\jaxrpc.jar;%AXIS_HOME%\lib\saaj.jar;%AXIS_HOME%\lib\wsdl4j-1.5.1.jar;%AXIS_HOME%\lib\log4j-1.2.8.jar;E:/thirdparty/activation/activation.jar;E:/thirdparty/activation/mail.jar
二、编写DII(Dynamic Invocation Interface )方式web服务
1.编写服务端程序HelloClient
public 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
四、编写wsdd发布web服务,编写stub client访问web服务
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() ; } } }
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."; serviceHandler.setOption("accesses", numAccesses); System.out.println(result); } catch (Exception e) { throw AxisFault.makeFault; } } }
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>
3.将编译后的文件拷贝到AXIS_HOME/WEB-INF/classes下,如:D:\tomcat\webapps\axis\WEB-INF\classes
4.发布服务:
java org.apache.axis.client.AdminClient deploy.wsdd
5.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); } } }
