Apacha Cocoon Web applications differ from conventional websites in that web applications can create a dynamic response.Many websites deliver only static pages.A web application can interact with databases and business logic engines to customize a response. Web applications based on JavaServer Pages sometimes commingle database code,page design code,and control flow code.In practice,we find that unless these concerns are Java 5 for Struts 1 separated,larger applications become difficult to maintain. See Also One way to separate concems in a software application is to use a Model-View-Controller(MVC)architecture.The Model represents the business or database code,the View represents the page design code,and the Controler represents the navigational code.The Struts framework is designed to help developers create web applications that utilize a MVC architecture maven The framework provides three key components: .A 'request'handler provided by the application developer that is mapped to a standard URI. .A 'response'handler that transfers control to another resource which completes the response. .A tag library that helps developers create interactive form-based applications with server pages The framework's architecture and tags are buzzword compliant.Struts works well with conventional REST applications and with nouveau technologies like SOAP and AJAX. The Apache Struts Project The Apache Struts Project is the open source community that creates and maintains the Apache Struts framework.The project consists of a diverse group of volunteers who share common values regarding collaborative,community-based open source development.The Apache Struts Project is proud to share these values with our parent organization: The Apache Software Foundation. that joins the vanous elements of the standard Java platform into a coherent whole.Our goal is to leverage existing standards by producing the missing pieces we need to create enterprise-grade applications that are easy to maintain over time. The Apache Struts Project offers two major versions of the Struts framework.Struts 1 is recognized as the most popular web application framework for Java.The 1.x framework is mature,well-documented,and widely supported.Struts 1 is the best choice for teams who value proven solutions to commo probiems. Struts 2 was originally known as Webwork 2.After working independently for several years,the Webwork and Struts communities joined forces to create Struts 2.The 2.x ■问宽模式合E打开B000零下莱，司国国Q10%

OVAL ·Bid o Easy startup -Jumpstart new projects with our bootstrap tutorial and template application or Sitegraph Maven archetype. Sitemesh o Improved Design-Code clean against HTTP-independant framework interfaces o Enhanced Tags -Code less with stylesheet-driven form tags that provide their own markup. o Stateful Checkboxes -Avoid special handling with smart checkboxes that know when they are toggled. r3 ft Doc o Flexible Cancel Buttons-Go directly to a different action on cancel. How to Help FAO First-class AJAX support -Add interactivity and flexibility with AJAX tags that look and feel just like standard Struts tags. o Easy Spring integration-Inject dependencies into Actions using Spring without glue code or red tape.(Plexus support also available. PMC Charter o Enhanced Results -Do more with speciality results for JasperReports,JFreeChart,Action Sandbox Source Repository chaining,and file downloading. Modules o PoJO forms-No more ActionForms!Use any JavaBean to capture form input or put properties XWork:Core directly on an Action class.Use both binary and String properties! o POJO Actions-Use any class as an Action class -even the interface is optional! ·Deploy o Easy plugins -Add framework extensions by dropping in a JAR.No manual configuration required! Struts 2 Maven Bundled plugins add support for JavaServer Faces,JasperReports,JFreechart,Tiles,and more . o Integrated profiling-Peek inside Struts2 to find where the cycles are going! Project Documentation o Precise Error Reporting-Flip directly to the location and line of an error ·aintain! o Easy-to-test Actions Test Struts2 Actions directly,without resorting to mock HTTP objects. Integration o Intelligent Defaults -Skip obvious and redundant settings.Most framework configuration Dependencies Dependency elements have a default value that we can set and forget.Say it once! o Easy-to-customize controller-Customize the request handling per action,if desired.Struts2 only does what you want it to do! Distribution o Integrating Debugging-Research problem reports with built-in debugging tools. o Easy-to-tweak tags-Customize tag markup by editing a FreeMarker template.No need to grok e Tracking the taglib API!JSP,FreeMarker,and Velocity tags are fully supported. agement 完毕 □切换浏览模式©打开d@●○四南下载·同日0)Q100%·
