环境：axis2 1.4, spring1.2 或者 spring2.0， tomcat6.0, windows vista

由于项目需要搭建一个良好的架构，我选择了用axis2和spring整合。不过再还没有做的时候，就听同事和网上的朋友说axis2和spring整合是多么难的事，使得我有一种极度想挑战它的心理，哈，其实整合起来非常的容易，不过网上介绍axis2的不多。我是用axis2官方网站的方法做整合的。地址：http://ws.apache.org/axis2/1_4_1/spring.html
官方网站上介绍两种方式整合，一种是我们所熟悉的applicationContext.xml放在和web.xml同一级的目录下,第二种是放在aar里面。因为任务上的一些因素，我选用第一种方式，而且我也只记录第一种，第二种我没有研究，我怕说错了误人子弟，好啦，开始。

1、首先，需要axis2.war，根据它的目录结构我们修改自己的web应用。只需拷贝axis2/WEB-INF/目录下的所有文件到自己的web项目下就可以了，记得要覆盖所有（axis2-web这个文件夹是包含axis2整个的管理界面，可有可无，不过要用的话，记得它是放在和WEB-INF的同级目录下），其实我们就是有点像在整个的axis2工程上做二次开发。
(第一步的作用主要是COPY包文件和WEB.XML配置文件)

2、我们像做所有其它的Web项目一样，用到spring的时候拷贝spring.jar到WEB-INF/lib目录下，然后在web.xml同级的目录下建立一个 applicationContext.xml，并且在applicationContext.xml引用相应的DTD或XSD（spring1.2引用的是DTD，spring2.0引用的是XSD），然后会在web.xml中加入这一段（当然，你可以选择用其它方式配置spring对web项目的支持）。

  <listener >       <listener-class > org.springframework.web.context.ContextLoaderListener </ listener-class >  </listener >  <context-param >       <param-name > contextConfigLocation </ param-name >       <param-value > /WEB-INF/applicationContext.xml </ param-value >  </context-param >

将上述代码插入Axis2的web.xml后出现一下错误：The content of element type "web-app" must match "(icon?,display-
name?,description?,distributable?,context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-
mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-env-
ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)".
- No grammar constraints (DTD or XML schema) detected for the document.
原因: 由于我用的是 Axis2-1.6.2，采用的web-app版本是2.3，所以web.xml里面会出现<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> 我当时将上述代码插入的是web.xml最后，上面都是定义的是servlet，所以会报错。

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app>    <display-name>DeviceRestration</display-name>         <servlet>        <servlet-name>AxisServlet</servlet-name>        <display-name>Apache-Axis Servlet</display-name>        <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>        <!--<init-param>-->        <!--<param-name>axis2.xml.path</param-name>-->        <!--<param-value>/WEB-INF/conf/axis2.xml</param-value>-->        <!--<param-name>axis2.xml.url</param-name>-->        <!--<param-value>http://localhost/myrepo/axis2.xml</param-value>-->        <!--<param-name>axis2.repository.path</param-name>-->        <!--<param-value>/WEB-INF</param-value>-->        <!--<param-name>axis2.repository.url</param-name>-->        <!--<param-value>http://localhost/myrepo</param-value>-->        <!--</init-param>-->        <load-on-startup>1</load-on-startup>    </servlet>        <servlet>        <servlet-name>AxisAdminServlet</servlet-name>        <display-name>Apache-Axis AxisAdmin Servlet (Web Admin)</display-name>        <servlet-class>            org.apache.axis2.webapp.AxisAdminServlet</servlet-class>    </servlet>        <!-- servlet>        <servlet-name>SOAPMonitorService</servlet-name>        <display-name>SOAPMonitorService</display-name>        <servlet-class>org.apache.axis2.soapmonitor.servlet.SOAPMonitorService</servlet-class>        <init-param>            <param-name>SOAPMonitorPort</param-name>            <param-value>5001</param-value>        </init-param>        <init-param>            <param-name>SOAPMonitorHostName</param-name>            <param-value>localhost</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet -->        <servlet-mapping>        <servlet-name>AxisServlet</servlet-name>        <url-pattern>/servlet/AxisServlet</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>AxisServlet</servlet-name>        <url-pattern>*.jws</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>AxisServlet</servlet-name>        <url-pattern>/services/*</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>AxisAdminServlet</servlet-name>        <url-pattern>/axis2-admin/*</url-pattern>    </servlet-mapping>    <!-- servlet-mapping>        <servlet-name>SOAPMonitorService</servlet-name>        <url-pattern>/SOAPMonitor</url-pattern>    </servlet-mapping -->        <mime-mapping>        <extension>inc</extension>        <mime-type>text/plain</mime-type>    </mime-mapping>   <welcome-file-list>      <welcome-file>index.jsp</welcome-file>      <welcome-file>index.html</welcome-file>      <welcome-file>/axis2-web/index.jsp</welcome-file>    </welcome-file-list>    <error-page>      <error-code>404</error-code>      <location>/axis2-web/Error/error404.jsp</location>    </error-page>    <error-page>        <error-code>500</error-code>        <location>/axis2-web/Error/error500.jsp</location>    </error-page>         <span style="color:#ff0000;"> <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></span>  </web-app>

解决办法：将这段代码粘贴到第一个servlet标签前面，问题就不会出现了，如下：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app>    <display-name>DeviceRestration</display-name>    <span style="background-color: rgb(255, 0, 0);"> <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>         </span>    <servlet>        <servlet-name>AxisServlet</servlet-name>        <display-name>Apache-Axis Servlet</display-name>        <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>        <!--<init-param>-->        <!--<param-name>axis2.xml.path</param-name>-->        <!--<param-value>/WEB-INF/conf/axis2.xml</param-value>-->        <!--<param-name>axis2.xml.url</param-name>-->        <!--<param-value>http://localhost/myrepo/axis2.xml</param-value>-->        <!--<param-name>axis2.repository.path</param-name>-->        <!--<param-value>/WEB-INF</param-value>-->        <!--<param-name>axis2.repository.url</param-name>-->        <!--<param-value>http://localhost/myrepo</param-value>-->        <!--</init-param>-->        <load-on-startup>1</load-on-startup>    </servlet>        <servlet>        <servlet-name>AxisAdminServlet</servlet-name>        <display-name>Apache-Axis AxisAdmin Servlet (Web Admin)</display-name>        <servlet-class>            org.apache.axis2.webapp.AxisAdminServlet</servlet-class>    </servlet>        <!-- servlet>        <servlet-name>SOAPMonitorService</servlet-name>        <display-name>SOAPMonitorService</display-name>        <servlet-class>org.apache.axis2.soapmonitor.servlet.SOAPMonitorService</servlet-class>        <init-param>            <param-name>SOAPMonitorPort</param-name>            <param-value>5001</param-value>        </init-param>        <init-param>            <param-name>SOAPMonitorHostName</param-name>            <param-value>localhost</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet -->        <servlet-mapping>        <servlet-name>AxisServlet</servlet-name>        <url-pattern>/servlet/AxisServlet</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>AxisServlet</servlet-name>        <url-pattern>*.jws</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>AxisServlet</servlet-name>        <url-pattern>/services/*</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>AxisAdminServlet</servlet-name>        <url-pattern>/axis2-admin/*</url-pattern>    </servlet-mapping>    <!-- servlet-mapping>        <servlet-name>SOAPMonitorService</servlet-name>        <url-pattern>/SOAPMonitor</url-pattern>    </servlet-mapping -->        <mime-mapping>        <extension>inc</extension>        <mime-type>text/plain</mime-type>    </mime-mapping>   <welcome-file-list>      <welcome-file>index.jsp</welcome-file>      <welcome-file>index.html</welcome-file>      <welcome-file>/axis2-web/index.jsp</welcome-file>    </welcome-file-list>    <error-page>      <error-code>404</error-code>      <location>/axis2-web/Error/error404.jsp</location>    </error-page>    <error-page>        <error-code>500</error-code>        <location>/axis2-web/Error/error500.jsp</location>    </error-page>          </web-app><span style="font-weight: bold;"></span>

3、发布整个项目发部到tomcat上，测试起动服务有没有问题。（一般不会是有问题，我们现在做的只是在axis2这个工程里添加了spring的jar包和在原有的axis2工程的web.xml加上了对spring的支持）。起动没问题的话就访问下http://<host>:<port>/<project name>/services/Version?wsdl，只要成功就可以了，下面进入正题。

4、写一个接口。（体现spring面向接口编程的好处）

package com.hp.bean;public   interface  MyBean {     public  String echo();}

5.实现这个接口

package com.hp.bean;public   class  MyBeanImpl implements MyBean {     public  String echo() {                 return   "Merry" ;    }}

6、写一个Web Service

package com.hp.service;import com.hp.bean.MyBean;public   class  SpringAwareService {     private  MyBean myBean;     public   void  setMyBean(MyBean myBean) {         this .myBean = myBean;    }         public  String response(){                 return  myBean.echo() +  " Christmas!" ;    }}

7、编写applicationContext.xml.（记住第一个bean,也就是applicationContext那个一定要有）

    <bean id= "applicationContext"         class = "org.apache.axis2.extensions.spring.receivers.ApplicationContextHolder"  />    <bean id= "springAwareService"         class = "com.hp.service.SpringAwareService" >        <property name= "myBean"   ref = "myBean"  />    </bean>    <bean id= "myBean"   class = "com.hp.bean.MyBeanImpl" ></bean>

8、在WEB-INF/services/下新建一个文件夹，这个名字可以起的随便，我们就起做test吧，然后在WEB-INF/services/test/下建立META-INF这个目录，最后在WEB-INF/services/test/META-INF/下建立services.xml,文件内容是：

<service name= "SpringAwareService" >    <description>simple spring example</description>    <parameter name= "ServiceObjectSupplier" >        org.apache.axis2.extensions.spring.receivers.SpringAppContextAwareObjectSupplier    </parameter>    <parameter name= "SpringBeanName" >springAwareService</parameter>    <messageReceivers>        <messageReceiver mep= "http://www.w3.org/2004/08/wsdl/in-only"             class = "org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"  />        <messageReceiver mep= "http://www.w3.org/2004/08/wsdl/in-out"             class = "org.apache.axis2.rpc.receivers.RPCMessageReceiver"  />    </messageReceivers></service>

这回再发布一下，在没有异常的情况下。访问一下http://<host>:<port>/<project name>/services/SpringAwareService?wsdl 看看
