webservice

以前对axis 生成web service一直比较糊涂，发现个人说个人的，好像有很多方法一样，最近特意查了查资料总结一下。

axis 生成webservice有3 种方式，

1, Dynamic invocation interface

2, Dynamic proxy

3, sub

下面分别做简单介绍

   在开始之前先环境配置：
    下载axis 包解压，把webapps/axis 下的所有文件都拷贝到你的web 工程下，
     这样你就可以在你工程里生成web service和利用一些axis提供的工具.

     打开： http://localhost:9081/TestWebService/index.jsp

      这里去验证你的环境是否建立成功。

     在电脑环境变量里增加

     AXIS_HOME: C:\MyThings\book\program\axis-1_4
     AXIS_LIB : C:\MyThings\book\program\axis-1_4\lib
     AXISCLASSPATH : 
C:\MyThings\book\program\axis-1_4\lib\axis.jar;C:\MyThings\book\program\axis-1_4\lib\axis-ant.jar;C:\MyThings\book\program\axis-1_4\lib\commons-discovery-0.2.jar;C:\MyThings\book\program\axis-1_4\lib\commons-logging-1.0.4.jar;C:\MyThings\book\program\axis-1_4\lib\jaxrpc.jar;C:\MyThings\book\program\axis-1_4\lib\log4j-1.2.8.jar;C:\MyThings\book\program\axis-1_4\lib\saaj.jar;C:\MyThings\book\program\axis-1_4\lib\wsdl4j-1.5.1.jar;C:\MyThings\book\program\axis-1_4\lib\activation.jar;C:\MyThings\book\program\axis-1_4\lib\mail-1.4.jar

这里注意我把mail-1.4.jar 和 activation.jar也加进来了，这两个本来不在lib目录下，但是axis需要依赖我就加进来了

   http://localhost:9081/TestWebService/servlet/AxisServlet
   可以查看现在服务器上都部署了那些服务

   第1种

　　　　动态接口调用，使用及时发布，用户只需提供java类源代码，axis会自动处理的

　　　　heloWorld.java

 public class HelloWorld{
        public String sayHello(){
               return "Hello World";
        }
       }

将hellWorld.java 拷贝到　%TOMCAT_HOME%\webpps\axis下，改名为HelloWorld.jws，　这样就发布成功了。

　测试代码：

　

import java.net.URL;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class CitiCardSericeTest {

	/**
	 * @param args
	 * @throws Exception 
	 */
	public static void main(String[] args) throws Exception {

		String endpoint = "http://localhost:8080/axis/HelloWorld.jws";
		Service service = new Service();
		Call call = (Call) service.createCall();
		call.setTargetEndpointAddress(new URL(endpoint));
		call.setOperationName("sayHello");
		String res = (String) call.invoke(new Object[] {});
		System.out.println(res);

	}

}

如果复杂对象：
QName qn=new QName("urn:beanservice","User");
		call.registerTypeMapping(User.class, qn, new BeanSerializerFactory(User.class,qn), new BeanDeserializerFactory(User.class,qn));
        User user=new User();
        user.setAge("10");
        user.setName("duant");
        String res = (String) call.invoke(new Object[] {user});
        System.out.println(res);

或者
  call.addParameter( "arg1", qn, ParameterMode.IN );

第2种　Dynamic proxy
将HelloWorld.java编译成HelloWorld.class 放到　%TOMCAT_HOME%\webapps\axis\WEB-INF\classe下

　在 %TOMCAT_HOME%\webapps\axis\WEB-INF下建立deploy.wsdd文件，soap服务发布描述文件

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
	xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
	
	
	<service name="HelloWorld" provider="java:RPC">
		<parameter name="className"  value="HelloWorld" />
		<parameter name="allowedMethods" value="*" />

	</service>
	
</deployment>

在doc目录下到 %TOMCAT_HOME%\webapps\axis\WEB-INF,命令
　java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient deploy.wssd

就会发现多了一个servver-config.wsdd文件，这个就是配置文件，
访问　http://localhost:8080/axis/servlet/AxisServlet

测试代码：

import java.net.URL;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class CitiCardSericeTest {

	/**
	 * @param args
	 * @throws Exception 
	 */
	public static void main(String[] args) throws Exception {

		String endpoint="http://localhost:8080/axis/services/HelloWorld"; //和１不同
		Service service = new Service();
		Call call = (Call) service.createCall();
		call.setTargetEndpointAddress(new URL(endpoint));
		call.setOperationName("sayHello");
		String res = (String) call.invoke(new Object[] {});
		System.out.println(res);

	}

}

第3种 stub 方式

package com.webService;

public class OrderService {
	public String orderProduce(String name, String address, String item, int quantity, Card card){
		String orderInfo=name+" "+address+" "+item+" "+card.getName();
		return orderInfo;
	}
}

package com.webService;

public class Card {
	private String name;
	private String age;
	
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

编写完代码后，在WEB-INF 下新建立一个文件 deploy.wsdd

这里需要注意beanMapping,因为card是一个java bean.

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
	xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
	
	
	<service name="OrderService" provider="java:RPC">
		<parameter name="className"  value="com.webService.OrderService" />
		<parameter name="allowedMethods" value="*" />

               <beanMapping languageSpecificType="java:com.webService.Card"
		qname="myNsn:Card" xmlns:myNsn="urn:BeanService" />
	</service>
	
</deployment>

这个时候已经完成了代码编写，如果你的环境是好的，就可以进入发布环节，如果环境没好，请参考环境建立部分。

在WEB-INF下面执行命令

java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient -lhttp://localhost:9081/TestWebServices/services/orderService  deploy.wsdd

系统提示 <Admin>Done processing </Admin>

就说明发布成功，可以去 http://localhost:9081/TestWebService/servlet/AxisServlet 查看已经部署结果，

可以用 http://localhost:9081/TestWebServices/services/orderService?wsdl

获得这个service 的wsdl 文件

测试这个webservice时可以用 WSDL2Java 生成测试的类，

执行命令：

java -cp %AXISCLASSPATH% org.apache.axis.wsdl.WSDL2Java -o c:\\temp -p com.webService orderService.wsdl

就可以根据wsdl文成生成客户端调用代码类，

card.java, OrderService_PortType.java, OrderServiceService.java, OrderServiceServiceLocator.java, OrderServiceSoapBindingStub.java

调用类

package com.webService;

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

public class Client {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		OrderServiceServiceLocator locator=new OrderServiceServiceLocator();
		try {
			OrderService_PortType service=locator.getOrderService();
Card card=new Card():
card.setName("laoslais");
			String res=service.orderProduce("one", "two", "three", 2, card);
			System.out.println(res);
		} catch (ServiceException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (RemoteException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

}

执行就的到结果： one two three

handler:

package com.webService.haddler;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;

import javax.xml.soap.SOAPException;

import org.apache.axis.AxisFault;
import org.apache.axis.Handler;
import org.apache.axis.MessageContext;
import org.apache.axis.handlers.BasicHandler;

public class LogHandler extends BasicHandler {


	private static final long serialVersionUID = 1L;

	public void invoke(MessageContext context) throws AxisFault {
		Handler handler=context.getService();
		String filename=(String) this.getOption("filename");
		

		try {
			FileOutputStream fos=new FileOutputStream(filename,true);
			PrintWriter write=new PrintWriter(fos);
			Integer counter=(Integer)handler.getOption("accesses");
			if(counter==null){
				counter=new Integer(1);
			}
			
			counter=new Integer(counter.intValue()+1);
			Date date=new Date();
			context.getMessage().writeTo(System.out);
			String result="date web service:"+context.getTargetService()+" call "+counter;
			
			handler.setOption("accesses", counter);
			write.println(result);
			write.close();
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (SOAPException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

}

deploy.wsdd:

<service name="OrderService" provider="java:RPC">
		<parameter name="className"  value="com.webService.OrderService" />
		<parameter name="allowedMethods" value="*" />
		<requestFlow>
		<handler name="logging" type="java:com.webService.haddler.LogHandler">
		 <parameter name="filename" value="c:\\temp\\myservice.log" />
		</handler>
		</requestFlow>
	</service>

客户端代码：

private static Logger logger=Logger.getLogger(AbstractServiceInvoke.class);
	private GbLogger m_gblog;
	private URL endPoint;
	protected Call call;
	
	public AbstractServiceInvoke(URL endPoint) throws ServiceException{
		this.endPoint = endPoint;
		Service service = new Service();

		this.call = (Call) service.createCall();
		this.call.setTargetEndpointAddress(this.endPoint);
		this.setCommonlPropety();
	}
	
	public URL getEndPoint() {

	}
	
	protected void setCommonlPropety(){

		call.setProperty(org.apache.axis.client.Call.SEND_TYPE_ATTR, Boolean.FALSE);
	    call.setProperty(org.apache.axis.AxisEngine.PROP_DOMULTIREFS, Boolean.FALSE);
	    call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS);
	}
	
	protected void registerTypeMapping(Class cls,QName qn){
		call.registerTypeMapping(cls, qn, new BeanSerializerFactory(cls,qn), new BeanDeserializerFactory(cls,qn)); 
	}
	
	protected void registerTypeMapping(String name,Class cls){
		QName qn=new QName("urn:beanservice",name);
		call.registerTypeMapping(cls, new QName("urn:beanservice",name), new BeanSerializerFactory(cls,qn), new BeanDeserializerFactory(cls,qn)); 
	}
	
	protected void registerTypeMapping(Class cls){
		String name=cls.getSimpleName();
		this.registerTypeMapping(name, cls);
	}
	
	
	protected void setInputType(QName qn,Class cls){
		call.addParameter(qn.getLocalPart(), qn,cls, ParameterMode.IN );
	}
	
	protected void setInputType(String name,Class cls){
		QName qn=new QName("urn:beanservice",name);
		call.addParameter(name, qn,cls, ParameterMode.IN );
	}
	
	protected void setInputType(Class cls){
		String name=cls.getSimpleName();
		this.setInputType(name, cls);
	}
	
	protected void setReturnType(Class cls){
		this.call.setReturnClass(cls);
	}
	
	protected Object invokeMethod(Object input,Class output,String operationName) throws RemoteException{
		String DEBUG_HDR = Utilities.getMethodInfo();
		
		try{

			Class inputCls=input.getClass();
			
			if(m_gblog != null){
				m_gblog.info(DEBUG_HDR + " input class:"+inputCls.getSimpleName());
			}else{
				logger.debug(DEBUG_HDR + " input class:"+inputCls.getSimpleName());
			}
			this.registerTypeMapping(inputCls);
			this.setInputType(inputCls);
			
			this.registerTypeMapping(output);
			this.setReturnType(output);
			if(m_gblog != null){
				m_gblog.info(DEBUG_HDR + " return class:"+output.getSimpleName());
			}else{
				logger.debug(DEBUG_HDR + " return class:"+output.getSimpleName());
			}
			
			this.call.setOperationName(operationName);
			if(m_gblog != null){

			}else{
				logger.debug(DEBUG_HDR + " operationName:"+operationName);
			}
			
			Object res=this.call.invoke(new Object[] {input});
			return res;
		}finally{
			this.printDebugInfo();
		}
	}
