补充点基础知识. Path mappings are used to map a URI to a contexts, handlers and servlets.
The following types of mapping are supported and applied in the order presented.
Absolute Mapping Path Spec: /path
Will match: /path path=/path info=<null>
Will not match: / /path/ /path/info /path/info.jsp /other</null>
Prefix Mapping Path Spec: /path/*
Will match: /path path=/path info=<null> /path/ path=/path info=/ /path/info path=/path info=/info /path/info.jsp path=/path info=/info.jsp
Will not match: / /other</null>
Suffix Mapping Path Spec: *.jsp
Will match: /path/info.jsp path=info=/path/info.jsp
Will not match: / /path /path/ /path/info /other
Default Mapping Path Spec: /
Will match: / path= info=/ /path path= info=/path /path/ path= info=/path/ /path/info path= info=/path/info /path/info.jsp path= info=/path/info.jsp /other path= info=/other
Will not match:
Typical examples
Context and Servlet with path Context Path Spec : /context/* Servlet Path Spec : /servlet/*
URI ContextPath ServletPath PathInfo ========================================================= /context/servlet /context /servlet null /context/servlet/ /context /servlet / /context/servlet/x /context /servlet /x
Default Context Context Path Spec : / Servlet Path Spec : /servlet/*
URI ContextPath ServletPath PathInfo ========================================================= /servlet "" /servlet null /servlet/ "" /servlet / /servlet/x "" /servlet /x
Context and Suffix Servlet Context Path Spec : /context/* Servlet Path Spec : *.txt
URI ContextPath ServletPath PathInfo ========================================================= /context/xxx.txt /context "" /xxx.txt
Context and Default Servlet Context Path Spec : /context/* Servlet Path Spec : /
URI ContextPath ServletPath PathInfo ========================================================= /context/xxx /context "" /xxx
Default Context and Servlet Context Path Spec : / Servlet Path Spec : /
URI ContextPath ServletPath PathInfo ========================================================= /xxx "" "" /xxx
