当处理 requestDispatcher 和资源路径时,路径是否主要以
For example: I have on servlet defined under:
<url-pattern>/handlers/FrontHandler</url-pattern>
和 lt;url-patern>/ handlers/ sub/ secondHandler</ url-patrtern> 中的另一种资源, 即使两个类别在不同的软件包中存在, 此资源还是与前一种资源相对的?
我是否理解正确? 我是否也必须使用 < code>. / 才能像普通 paht 导航一样提升一个级别?
谢谢 谢谢
The javadoc 说:
The pathname specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root.
因此路径与类名称无关, 与给定路径所在的资源( 静态, 如 html 文件, 或动态, 如 用于给定 URL 模式的服务器) 有关的一切 。
我将避免使用相对路径:很难知道他们解决了哪条绝对路径,它们又变得脆弱,因为如果你将您的服务器映射到另一个 URL 上,它们就会断裂。
