速度 + Struts2 + Sitemesh + Spring +Hibernate 集成 如何配置 web.xml？

Question

我需要创建一个应用程序，使用 Struts2 作为 MVC，使用 Hibernate 进行数据访问，并在业务逻辑中使用 Spring。 我还需要使用 Velocity 进行演示，使用 sitemesh 进行模板化。

集成 Hibernate 和 Spring 很容易，但将 spring、sitemesh 和 Velocity 与 Struts2 集成在一起 我不清楚，但我可以在 Struts2 中单独使用速度、弹簧和 sitemsh。

当然，如本示例所示 http://www.rkcole.com/articles /struts/crudTutorial/step4.html sitemesh和spring可以与struts2集成，配置web.xml为

<listener> 
<listener-class> 
org.springframework.web.context.ContextLoaderListener 
</listener-class> 
</listener> 

<filter> 
<filter-name>sitemesh</filter-name> 
<filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class> 
</filter> 


<filter-mapping> 
<filter-name>sitemesh</filter-name> 
<url-pattern>/*</url-pattern> 
<dispatcher>FORWARD</dispatcher> 
</filter-mapping> 

现在我的任务是将velocity与这个组合集成............

通常要集成Velocity和struts2我使用以下

<servlet-class> 
org.apache.velocity.tools.view.servlet.VelocityViewServlet 
</servlet-class> 
<load-on-startup>10</load-on-startup> 
</servlet> 
<servlet-mapping> 
<servlet-name>velocity</servlet-name> 
<url-pattern>*.vm</url-pattern> 
</servlet-mapping> 

.. ...................................................... .........................................

现在我的问题是如何设置`

 <servlet-mapping>

` ，它仅适用于速度，或 simemesh 或必须进行不同的设置，

请让我知道如何继续，如果可以，请回复完整的 web.xml 和其他要遵循的步骤。

是的，经过大量阅读和搜索，我终于得到了这个 web.xml......

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>
</context-param>



<!-- All the filters starts here-->

<filter>
    <filter-name>struts-cleanup</filter-name>
    <filter-class>org.apache.struts2.dispatcher.StrutsPrepareFilter</filter-class>
</filter>


<!-- This is used to integrate sitemesh with Struts2-->

<!-- 
I am using Velocity to create sitemesh decorators so I have to use 

  VelocityPageFilter    to integrate

  Sitemesh  (i.e. Sitemesh in velocity)  +  Struts2    
In the web.xml, the VelocityPageFilter should be placed between the
  ActionContextCleanUp (StrutsPrepareFilter since 2.1.3  )  and
and the    FilterDispatcher (StrutsExecuteFilter  since 2.1.3)  
 -->

<filter>
    <filter-name>sitemesh</filter-name>
    <filter-class>org.apache.struts2.sitemesh.VelocityPageFilter</filter-class>

<!-- Spring Integration-->

    <!--Finally since I am velocity pages in struts2 MVC I am using

    <param-name>org.apache.velocity.properties</param-name>
    <param-value>/WEB-INF/velocity.properties</param-value>
  </init-param>
  </servlet>


<!-- Map *.vm files to Velocity -->
<servlet-mapping>
  <servlet-name>velocity</servlet-name>
  <url-pattern>*.vm</url-pattern>
</servlet-mapping>



    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>


    <welcome-file-list>
        <welcome-file>index.vm</welcome-file>
    </welcome-file-list>


   </web-app>

希望这很好，将测试并让你知道。

干杯............
