结论:
• '/XXX/*' • '*.html' • '/' • 其他都是精确映射 例: '/XXX/Y*.html' 只能映射/XXX/Y*.html 的URL请求. 例: '/XXX' 只可以映射/XXX的URL请求. 引用
10.2 Specification of Mappings In the web application deployment descriptor, the following syntax is used to define mappings: • A string beginning with a '/' character and ending with a '/*' postfix is used as a path mapping. • A string beginning with a '*.' prefix is used as an extension mapping. • All other strings are used as exact matches only • A string containing only the '/' character indicates that servlet specified by the mapping becomes the "default" servlet of the application. 翻译如下: 10.2 映射规则说明 在web应用的部署描述中(web.xml)中, 以下语法结构用于定义映射: • 以'/'开头 并以'/*'结尾的字符串用于做路径的映射. • 以'*.'开头 用于做扩展的映射. • 其他的所有字符串都是只做精确映射. • 一个只是'/'的字符串 将当前这个servlet明确为应用的默认servlet. |
