4.如何使用已经定义?Schema
如何使用已经定义?Schema
(tng) (tng) Ofbiz 遵@ MVC 的设计模式，?View 端，?JSP 端主要?Ofbiz 定义?Tag 来显C或
(tng) (tng) 提取数据QControl 是一?Controller ServletQ我们在 Controller Servlet ?URI mapping
(tng) (tng) 配置文g中定义各 URL 应该指向什么程序，q样Q通过q个 mapping 配置文gQ可以保证我们各个页?br /> (tng) (tng) ?qing)具体处理程序之间的独立性，例我们可以通过修改q个配置文g可以改变某?Form ?Post Action
(tng) (tng) ?URLQ而不需要修改实际的 HTML ?JSP 代码?/p>
(tng) (tng) Ofbiz 中定义了(jin) Regions 的概念，卛_一?HTML 面分成几个区域Q像 Top, Left, Right, Main
(tng) (tng) {，通过q些 Regions 我们可以方便的组?UI 界面Qƈ且可以方便改变各部分所处的位置Q如我们可以
(tng) (tng) 把菜单很Ҏ(gu)的从上方Ud下方Q只需要改变(sh)个配|文件。Regions cM?HTML 中的 FrameQ但它是
(tng) (tng) 通过一个页面来l合界面QFrame 是通过几个面昄在不同的帧中QFrame 的控制比较复杂，而且需?br /> (tng) (tng) 改变相关的程序?/p>
(tng) (tng) ?Ofbiz 中，我们可以直接?JSP 中操?Schema 定义?ObjectQ即我们刚定义的 StudyCustomerQ?br /> (tng) (tng) CZ如下Q?/p>

(tng) q段E序挺容易理解，先是通过 delegator 创徏一?ObjectQ该 Object 会(x)?Ofbiz 自动同步?br />数据库中。然后通过 delegator ?findAll 取到所有已保存?ObjectQ最后通过一?Iterator 对象

?regions.xmlQ这两个文g是我们上面提到?mapping ?regions 配置文g?/p>
(tng) q两个文仉在：(x)c:\ofbiz\ofbiz\partymgr\webapp\WEB-INF 下，?controller.xml 中加入下?/p>
