【正文】 tly being added. If you don’t see what you need now, check back in a few months because it might have been added. And if you’re adding a new integration to your own webapplication, consider implementing it as a plugin and sharing it with others. Page Decoration and Layout Developing web applications usually means there is going to be a standard page layout that is used for the entire application, as well as a selection of additional layouts to be used for various modules, pages and wizards. Depending on whether your preference is to specify the layout, or to let the URL specify the layout, you will most likely choose either Struts Tilesxi or SiteMeshxii. Struts2 provides integrations for both these layout technologies. SiteMesh SiteMesh is installed by adding the pluginxiii into your web applications ―/WEBINF/lib‖ directory or by adding a dependency to your Maven2 ―‖ build file: dependency groupId/groupId artifactIdstruts2sitemeshplugin/artifactId version/version /dependency A servlet filter also needs to be configured. This filter enables access to the value stack from the SiteMesh decorators, and ensures that the ActionContext is cleaned up when the decorator has finished (and not before). 2 filter filternamestrutscleanup/filtername filterclass /filterclass /filter If you are using Freemarker or Velocity for page rendering, you will need to add one of these additional filters: filter filternamesitemesh/filtername filterclass /filterclass /filter filter filternamesitemesh/filtername filterclass /filterclass /filter Finally, the order of the filter mappings is important. Both the ―strutscleanup‖ and the ―sitemesh‖ (if used) filter need to be configured before the ―struts‖ (FilterDispatcher) filter: filtermapping filternamestrutscleanup/filtername urlpattern/*/urlpattern /filtermapping filtermapping filternamesitemesh/filtername urlpattern/*/urlpattern /filtermapping … filtermapping filternamestruts/filtername urlpattern/*/urlpattern /filtermapping The specific decorator files for the web application can now be developed, and configured to match specific URL patterns or metadata in ―‖. Tiles Apache Tiles, just like SiteMesh, is installed by adding the plugin xiv into your web applications ―/WEBINF/lib‖ directory or by adding a dependency to your Maven2 ―‖ build file: dependency groupId/groupId artifactIdstruts2tilesplugin/artifactId version/version 3 /dependency In order to load the tiles configuration, a servlet listener needs to be configured: listener listenerclass /listenerclass /listener The listener loads the ―‖ configuration file, which defines each tile for your application, from the ―WEBINF‖ directory. Unlike SiteMesh, Tiles are implemented as a new result type. Each action result that wishes to use a Tiles layout needs to provide the attribute ―type‖ with value ―tiles‖ (or alternately set the Tiles result to be the default), and provide the name of the tile to use. The Tile name needs to be defined in the configuration file ―‖. action name=my class= result type=tiles/result /action Version 2 of Tiles is used in Struts2. This version has not yet had a stable release and could undergo further change. For this reason Tiles support is currently marked as experimental in Struts2. Business Services / Dependency Injection The Spring Framework plugin is the preferred dependency injection (DI) or inversion of control (IoC) container for Struts2, and as such is responsible for providing fully configured business service instances to actions. There are several options available, each at different levels of stability: 雖然最終由于各種原因， Patrick Lightbody的愿望未能實現(xiàn)，但是 WebWork和 Struts Ti卻發(fā)現(xiàn)了二者在技術(shù)與開發(fā)人員這兩個層面上的共同之處，不久之后，兩個項目就在WebWork的技術(shù)基礎(chǔ)上進行了合 指導教師評審意見 1 英文部分： with Other Technologies In previous chapters we have covered the techniques for integrating external technologies with Struts2.
