JSF和Struts的区别概述,都采用taglib来处理表示层:在jsp页面中,二者都是采用一套标记库来处理页面的表示和model层的交互. 据说JSF的主要负责人就是struts的主要作者,所以二者的相似点还是有很多的. 都采用taglib来处理表示层:在jsp页面中,二者都是采用一套标记库来处理页面的表示和model层的交互. 二者都采用了bean来作为和jsp页面对应的model层.该model层保存了jsp页面上的数据,同时可以作一些验证工作,在struts中就是FormBean,在JS…

1. JSF入门 藉由以下的几个主题,可以大致了解JSF的轮廓与特性,我们来看看网页设计人员与应用程序设计人员各负责什么. 1.1简介JSF Web应用程序的开发与传统的单机程序开发在本质上存在着太多的差异,Web应用程序开发人员至今不可避免的必须处理 HTTP的细节,而HTTP无状态的 (stateless)本质,与传统应用程序必须维持程序运行过程中的信息有明显的违背,再则Web应用程序面对网站上不同的使用者同时的存取,其执行绪 安全问题以及资料验证.转换处理等问题,又是复杂且难以解决的. 另…

JSF通过定制标签与JSP集成.之前展示过的所有 JSF标签,<h:inputText>.<h:outputText>.<h:form> 和<f:view>等,都是定制标签.根据规范要求,JSF 实现必须通过提供访问所有标准组件.呈现器.验证器和转换器的定制标签来支持JSP.这些标签库(包括在JSF JAR中)列于表3-6中. 表3-6  JSF定制标签库 URI 名   称 通用前缀 说    明 http://java.sun.com/jsf/core…

JSF项目中实现基于RBAC模型的权限管理设计(二) 转 4.3 权限验证模块设计 一个好的权限管理机制在项目中应用时,最好不要让程序员在具体业务代码的方法中来判断用户权限.因为这意味着大量重复的代码.同时,也会导致权限机制的修改造成所有业务代码都需要修改一遍. 最好办法是实现与具体业务代码无关的独立的权限验证模块.这个模块可以拦截用户对资源的访问请求,并且在该请求被实施前做出权限判断,将权限不符的访问导向警告或提示页面. 在普通的JSP项目中,我们往往会利用Tomcat的Servlet fil…
