spring的强悍之处就在与它能和很多框架进行无缝的结合;在这里讲述一下它和axis的步骤(注意是axis不是axis2);

为了能说明问题,以一个demo为例;说到webservice自然不外乎服务端和客户端的开发了 ,在这里分别说明;

一服务端的开发:

1 把需要的jar放到工程目录下(必须的包为:wsdl4j-1.5.1.jar,spring.jar,saaj.jar,mail-1.4.jar,log4j-1.2.8.jar,

jaxrpc.jar,commons-logging-1.0.4.jar,commons-discovery-0.2.jar,axis-ant.jar,axis.jar,activation-1.1.jar)

2 开发源代码:因为这一步和业务相关,在这里不做讨论,但是必须有一个类继承ServletEndpointSupport,该类将发布成webService

具体的代码形如:

package com.ecgit.eccm.webservice;



import javax.xml.rpc.ServiceException;
import javax.xml.rpc.server.ServiceLifecycle;

import org.springframework.remoting.jaxrpc.ServletEndpointSupport;

import com.skywin.service.MyService;

public class InterchangeDataServiceImpl extends ServletEndpointSupport {

	private MyService service;
	
	protected void onInit() throws ServiceException {
		service=(MyService) getApplicationContext().getBean("MyService");
		
	}

	public String getMonthInterchange(String marketDate) {
		System.out.println("到达了Facade");
		service.doTrans(marketDate);
		return marketDate;
	}

}

业务层代码(仅仅写实现类,接口比较简单,所以省略):

package com.skywin.service;

import com.skywin.dao.MyDao;

public class MyServiceImpl implements MyService{
    private MyDao myDao;
	public void doTrans(String message) {
		myDao.doTrans(message);
		System.out.println("服务层运行了"+this.getClass().getName()+"----"+message);
		
	}
	public MyDao getMyDao() {
		return myDao;
	}
	public void setMyDao(MyDao myDao) {
		this.myDao = myDao;
	}
      
}

持久层代码(仅仅写实现类,接口比较简单,所以省略)

3 在web-inf目录下,建立一个名字为server-config.wsdd的文件,里面指定那些包的哪些类的哪些方法发布成webService,内容如下

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
	xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
	<handler name="URLMapper"
		type="java:org.apache.axis.handlers.http.URLMapper" />

	<!-- 系统服务 -->

	<service name="AdminService" provider="java:MSG">
		<parameter name="allowedMethods" value="AdminService" />
		<parameter name="enableRemoteAdmin" value="false" />
		<parameter name="className" value="org.apache.axis.utils.Admin" />
		<namespace>http://xml.apache.org/axis/wsdd/</namespace>
	</service>
	<service name="Version" provider="java:RPC">
		<parameter name="allowedMethods" value="getVersion" />
		<parameter name="className" value="org.apache.axis.Version" />
	</service>

	<!-- 自定义服务 -->
	<service name="MPSWebService" provider="java:RPC">
		<parameter name="className" value="com.ecgit.eccm.webservice.InterchangeDataServiceImpl" />
		<parameter name="allowedMethods" value="*" />
		 
	</service>
	 <!--  
	<beanMapping languageSpecificType="java:com.skywin.mps.sa.model.SPParamObject"
      			qname="ns1:SPParamObject" xmlns:ns1="urn:BeanService" /> 
   
      <beanMapping languageSpecificType="java:com.skywin.mps.sa.model.OrderSubItem"
      			qname="ns2:OrderSubItem" xmlns:ns2="urn:BeanService" />
      			
     <beanMapping languageSpecificType="java:java.util.List"
      			qname="ns3:List" xmlns:ns3="urn:BeanService" />  
     <beanMapping languageSpecificType="java:java.util.ArrayList"
      			qname="ns4:ArrayList" xmlns:ns4="urn:BeanService" />  
      -->
	<transport name="http">
		<requestFlow>
			<handler type="URLMapper" />
		</requestFlow>
	</transport>
</deployment>

4在web-inf目录下,建立spring配置文件(名字为applicationContext.xml),内容如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

	 <bean id="serviceFace" class="com.ecgit.eccm.webservice.InterchangeDataServiceImpl"></bean>
	 <bean id="MyService" class="com.skywin.service.MyServiceImpl">
	    <property name="myDao" ref="myDao"></property>
	 </bean>
	 <bean id="myDao" class="com.skywin.dao.MyDaoImpl"></bean>
</beans>

5 修改web.xml文件,主要是目的是增加一个和axis相关的servlet和启动spring ,内容大家都很熟悉了,代码如下:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
	xmlns="http://java.sun.com/xml/ns/j2ee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
	<servlet>
		<servlet-name>AxisServlet</servlet-name>
		<servlet-class>
			org.apache.axis.transport.http.AxisServlet
		</servlet-class>
		<load-on-startup>2</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>AxisServlet</servlet-name>
		<url-pattern>/services/*</url-pattern>
	</servlet-mapping>
	
	
	
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationContext.xml</param-value>
	</context-param>
	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>
</web-app>

到这里服务端的开发完毕了,如果每一步都没有问题,则将工程发布到应用服务器,在地址栏中输入:http://localhost:8080/aspring/services/MPSWebService?wsdl 回车就可以看到刚才分布的服务了;

二客户端的开发:

其实客户端没有怎么开发可言的,主要的工作就是利用服务的uri(即上面说的http://localhost:8080/aspring/services/MPSWebService?wsdl) 生成几个类,然后利用生成的类,传入参数就可以了,大体的步骤如下:

1 把需要的jar包引入工程,需要的jar基本上和服务端的一样,只是不需要spring.jar而已,在这里不在赘述;

2 利用服务端提供的uri生成类:

需要输入的命令如下

java org.apache.axis.wsdl.WSDL2Java http://localhost:8080/aspring/services/MPSWebService?wsdl -p com.skywin.mps.webservice.client

其中org.apache.axis.wsdl.WSDL2Java为包axis里面的类,用户需要进入到对应目录执行上述的命令;该类在编译时候需要其他的类,所以在执行上述命令中需要把下面的包加到classpath中 commons-logging-1.0.4.jar,commons-discovery-0.2.jar,jaxrpc.jar,saaj.jar,wsdl4j-1.5.1.jar

3 执行第2步的命令后,在client端可以得到四个类(InterchangeDataServiceImpl,InterchangeDataServiceImplService,InterchangeDataServiceImplServiceLocator,MPSWebServiceSoapBindingStub);

4,传入参数来调用服务端的服务:代码如下:

package aspring;

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;


import com.skywin.mps.webservice.client.InterchangeDataServiceImpl;
import com.skywin.mps.webservice.client.InterchangeDataServiceImplService;
import com.skywin.mps.webservice.client.InterchangeDataServiceImplServiceLocator;


public class Test {
	
	
	public static void main(String[] args) throws ServiceException, RemoteException {
		InterchangeDataServiceImplService server= new InterchangeDataServiceImplServiceLocator();
	    InterchangeDataServiceImpl serverDo=server.getMPSWebService();
	    serverDo.getMonthInterchange("funk");
	}
	
	
	
}

另外客户端也可以直接书写如下程序,运行下面的类也可以得到和上面一样的结果

package aspring;

import javax.xml.namespace.QName;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class Test2 {
	
	public static void main(String[] args) {
		
		

          try 

          {

                 String wsdlUrl= "http://localhost:8080/aspring/services/MPSWebService?wsdl";

                 String nameSpaceUri = "http://localhost:8080/aspring/services/MPSWebService";

                 // 创建调用对象 <o:p> </o:p>

                 Service service = new Service();

                 Call call = null;

                 call = (Call) service.createCall();

                 // 调用 getMessage

                 System.out.println(">>>getMessage");

                 call.setOperationName(new QName(nameSpaceUri, "getMonthInterchange"));

                 call.setTargetEndpointAddress(new java.net.URL(wsdlUrl));

                 String ret = (String) call.invoke(new Object[] { "ABC" });

                 System.out.println("return value is " + ret);

          } 

          catch (Exception e) 

          {

                 e.printStackTrace();

          } 
		
	}

}

三下载说明:asrping为服务端工程,aspringClient为客户端工程;鉴于流量问题,两个工程中的lib目录中都没有jar包,如果想下载的话,只需要把lib_001,lib_002中的包放到工程的lib目录就可以了(由于流量问题spring.jar和axis.jar没有上传)
