一、axis安裝 1.環(huán)境 J2SE SDK 1.3 or 1.4: 我使用 1.4.2 Servlet Container: 我使用Tomcat 5.0 2.到 http://ws./axis/網(wǎng)站下載axis安裝包 3.解壓縮安裝包，將AXIS_UNZIP_PATH\axis-version\webapps下的axis包拷貝到TOMCAT_HOME\webapps\下， 以下約定AXIS_HOME為該TOMCAT_HOME\webapps\axis目錄 4.啟動(dòng)tomcat,訪問http://localhost:8080/axis 檢查安裝是否成功 5.以上步驟執(zhí)行成功，可以開發(fā)webservice例子了 axis支持三種web service的部署和開發(fā)，分別為： 1。Dynamic Invocation Interface ( DII) 2。 Stubs方式 3。Dynamic Proxy方式 以下逐一講述web service在axis上的部署和開發(fā)，設(shè)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、編寫DII(Dynamic Invocation Interface )方式web服務(wù) 1.編寫服務(wù)端程序HelloClient public class HelloClient { public String getName(String name) { return "hello "+name; } } 2.將源碼拷貝到AXIS_HOME下，重命名為 HelloClient.jws 3.訪問連接http://localhost:8080/axis/HelloClient.jws?wsdl，頁面顯示axis自動(dòng)生成的wsdl 4.編寫訪問服務(wù)的客戶端 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、編寫Dynamic Proxy方式訪問服務(wù) 1.編寫部署服務(wù)端程序，同上邊DII方式，本次仍使用上邊部署的HelloClient 2.編寫代理接口 public interface HelloClientInterface extends java.rmi.Remote { public String getName(String name) throws java.rmi.RemoteException; } 3.編寫并執(zhí)行客戶端程序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/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() ; } } } 四、編寫wsdd發(fā)布web服務(wù)，編寫stub client訪問web服務(wù) 1.編寫服務(wù)端程序server,SayHello.java，編譯server.SayHello.java package server; public class SayHello { public String getName(String name) { return "hello "+name; } } 2.編寫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..編寫wsdd文件 deploy.wsdd <deployment xmlns="http://xml./axis/wsdd/" xmlns:java="http://xml./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.將編譯后的文件拷貝到AXIS_HOME/WEB-INF/classes下，如：D:\tomcat\webapps\axis\WEB-INF\classes 4.發(fā)布服務(wù)： java org.apache.axis.client.AdminClient deploy.wsdd 5.生成client stub文件 a:方式1 將SayHello.java拷貝到AXIS_HOME/下，重命名為SayHello.jws，執(zhí)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 執(zhí)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 執(zhí)行如下命令生成client stub java org.apache.axis.wsdl.WSDL2Java SayHello.wsdl -p client 生成的stub client文件列表為： 1。SayHello.java 2。SayHelloService.java。 3。SayHelloServiceLocator.java 4。SayHelloSoapBindingStub.java 6.編寫客戶端程序，編譯并執(zhí)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); } } } |
