Struts2+Tiles2开始着手

ApacheJavaJSPStrutsServlet 
阅读更多

今天看了一天的Struts 2的资料文档，对Struts 2 简化了部署与减少代码量等更多优点，非常有兴趣去了解，可能的话，可以推广起来的。

读完官方自带的showcase的主配置和主代码框架，依稀的感觉到单论Struts2+Spring2+Hibernate3.2而言，还是能够把老经验顺手沾来直接使用的，就是说可以做到简单的升级到 2.0版本来。但是我们大量采用的tiles部份，目前我了解的较少，单从配置上来说，就已经发生了一些改变，其他文件方面倒是没有什么改变。

这是原Struts1在struts.xml文件当中配置的：tiles相关的配置部份：

xml 代码
  1. <plug-in className="org.apache.struts.tiles.TilesPlugin">  
  2.     <set-property property="definitions-config"  
  3.         value="/WEB-INF/config/tiles-defs.xml" />  
  4.     <set-property property="definitions-parser-validate"  
  5.         value="true" />  
  6.     <set-property property="moduleAware" value="true" />  
  7. </plug-in>  

在struts2当中明显不再采用struts１著名的plugin技术了，直接在web.xml中多了这样的配置：

xml 代码
  1. <listener>  
  2.         <listener-class>  
  3.             org.apache.struts2.tiles.StrutsTilesListener   
  4.         </listener-class>  
  5. </listener>  

然后直接就配置tiles.xml文件，如下：

xml 代码
  1. <!DOCTYPE tiles-definitions PUBLIC   
  2.         "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"   
  3.         "http://struts.apache.org/dtds/tiles-config_2_0.dtd">  
  4.   
  5. <tiles-definitions>  
  6.   
  7.     <definition name="showcase.index" template="/tiles/layout.jsp">  
  8.         <put-attribute name="title" value="Tiles Showcase"/>  
  9.         <put-attribute name="header" value="/tiles/header.jsp"/>  
  10.         <put-attribute name="body" value="/tiles/body.jsp"/>  
  11.     </definition>  
  12.   
  13.     <definition name="showcase.freemarker" template="/tiles/layout.jsp">  
  14.         <put-attribute name="title" value="Tiles/Freemarker Showcase"/>  
  15.         <put-attribute name="header" value="/tiles/header.jsp"/>  
  16.         <put-attribute name="body" value="/tiles/body.ftl"/>  
  17.     </definition>  
  18.   
  19. </tiles-definitions>  

目前看起来，struts2使tiles的应用更加简化和快捷了。单论tiles2而言，还是比较复杂用的，但是struts简化他的部署了。

以下是在struts2中必须有的与tiels2相关的文件，考贝到项目的lib目录就ＯＫ了。

struts2-tiles-plugin.jar、tiles-api-2.0.4.jar、tiles-core-2.0.4.jar、tiles-jsp-2.04.jar

后三个文件，从tiles.apache.org下载tiles工程。

过段时间，我详细写出一些较完整的应用例子。

已经报了：

你用Role标签了吧？你加了一个title标签？

java.lang.ClassNotFoundException: org.apache.tiles.listener.TilesListener

我出现了这个错误,正在找,虽然报了 classnotfoundException , 但相关的jar文件都在lib目录下,所以有点闷
2 楼 beck 2007-11-04  
如果写： 
<definition name="test " extends="showcase.index"">   
   <put-attribute name="title" value="test"/>   
   <put-attribute name="header" value="/tiles/header2.jsp"/>   
    <put-attribute name="body" value="/tiles/body2.jsp"/>   
</definition>

它继承了showcase.index
然后在header2.jsp或者在body2.jsp中取action中传过来的参数，取不到，不知各位有没有发现这样的问题？
1 楼 tczengjin 2007-08-18   
<listener>  
        <listener-class>  
            org.apache.struts2.tiles.StrutsTilesListener   
        </listener-class>  
</listener>

请问当你这样配置的时候没出现严重: Error listenerStart错误吗？？应用无法加载，请问如何解决的？？
