概况：webservice主要用于跨平台数据共享。

提供一个axis的webservice例子供入门者学习：

1、项目结构

2、项目依赖的jar包：

3、目录说明：

4、webservice的发布配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">  

<globalConfiguration>
  <parameter name="sendMultiRefs" value="true"/>
  <parameter name="disablePrettyXML" value="true"/>
  <parameter name="dotNetSoapEncFix" value="true"/>
  <parameter name="enableNamespacePrefixOptimization" value="false"/>
  <parameter name="sendXMLDeclaration" value="true"/>
  <parameter name="sendXsiTypes" value="true"/>
  <parameter name="attachments.implementation" value="org.apache.axis.attachments.AttachmentsImpl"/>
</globalConfiguration>

  <handler type="java:org.apache.axis.handlers.http.URLMapper" name="URLMapper"/>   
  
  <!-- 参数字符串,返回字符串 -->
  <service name="getString" provider="java:RPC">   
    <parameter name="scope" value="request"/>
    <parameter name="allowedMethods" value="getString"/> 
	<parameter name="className" value="ws.UserWebserviceString"/>		
  </service>
  
  <!-- 参数对象,返回对象-->
  <service name="getUser" provider="java:RPC">   
    <parameter name="scope" value="request"/>
    <parameter name="allowedMethods" value="getUser"/> 
	<parameter name="className" value="ws.UserWebserviceObject"/>	
	
	<beanMapping
			languageSpecificType="java:bean.User"
			qname="ns1:User" xmlns:ns1="local:User" />	
  </service>
  
  <!-- 参数对象,返回对象数组-->
  <service name="getUserArray" provider="java:RPC">   
    <parameter name="scope" value="request"/>
    <parameter name="allowedMethods" value="getUserArray"/> 
	<parameter name="className" value="ws.UserWebserviceArray"/>	
	
	<beanMapping
		languageSpecificType="java:bean.User"
		qname="ns1:User" xmlns:ns1="local:User" />
		
	<arrayMapping innerType="ns1:User"
		xmlns:ns1="local:User"
		languageSpecificType="java:bean.User[]"
		qname="ns3:ArrayOfUser" xmlns:ns3="local:ArrayOfUser" />
		
  </service>
  
  <transport name="http">   
     
     <requestFlow>
		<handler type="URLMapper" />

	<parameter name="qs.wsdl" value="org.apache.axis.transport.http.QSWSDLHandler" />
		  
  </transport>
  
</deployment>

  
  <!-- <beanMapping
			languageSpecificType="bean.User"
			qname="ns1:User" xmlns:ns1="local:User" />
			
	<beanMapping
		languageSpecificType="java:com.mmds.ws.bean.FilterResult"

5、web项目的web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  
  <display-name>WebServiceDemo</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- webservice配置关键点 start -->
   <servlet>
		<servlet-name>AxisServlet</servlet-name>
		<servlet-class>org.apache.axis.transport.http.AxisServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>AxisServlet</servlet-name>
		<url-pattern>/services/*</url-pattern>
	</servlet-mapping>
  <!-- webservice配置关键点 end -->
  
</web-app>
