java基礎(chǔ)
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.apache.org/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(s).";
????????????serviceHandler.setOption("accesses",?numAccesses);
????????????System.out.println(result);
????????}?catch?(Exception?e)?{
????????????throw?AxisFault.makeFault(e);
????????}
????}
}
3..編寫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.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);
????????}
????}
}
