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.


1.    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:
2.    以'/'开头 并以'/*'结尾的字符串用于做路径的映射.
3.    以'*.'开头 用于做扩展的映射.
4.    一个只是'/'的字符串 将当前这个servlet明确为应用的默认servlet.
