简单的webservice开发例子

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

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

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、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

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、编写wsdd文件


deploy.wsdd

<?xml version="1.0" encoding="UTF-8"?><ns1:deployment xmlns:ns1="http://xml.apache.org/Axis/wsdd/" xmlns:java="http://xml.apache.org/Axis/wsdd/providers/java">    <ns1:handler name="print" type="java:LogHandler"/>    <ns1:service name="sayhello" provider="java:RPC">        <ns1:requestFlow>            <ns1:handler type="print"/>        </ns1:requestFlow>        <ns1:parameter name="className" value="server.SayHello"/>        <ns1:parameter name="allowedMethods" value="*"/>    </ns1:service></ns1: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);}}}
