Where can I find resources to learn Ant path style conventions? I've gone to the Ant site itself, but couldn't find any information on path styles.

回答1:

Ant-style path patterns matching in spring-framework:

The mapping matches URLs using the following rules:

? matches one character

* matches zero or more characters

** matches zero or more 'directories' in a path

{spring:[a-z]+} matches the regexp [a-z]+ as a path variable named "spring"

Some examples:

com/t?st.jsp - matches com/test.jsp but also com/tast.jsp or com/txst.jsp

com/*.jsp - matches all .jsp files in the com directory

com/**/test.jsp - matches all test.jsp files underneath the com path

org/springframework/**/*.jsp - matches all .jsp files underneath the org/springframework path

org/**/servlet/bla.jsp - matches org/springframework/servlet/bla.jsp but also org/springframework/testing/servlet/bla.jsp and org/servlet/bla.jsp

com/{filename:\\w+}.jsp will match com/test.jsp and assign the value test to the filename variable

回答2:

I suppose you mean how to use path patterns

If it is about whether to use slashes or backslashes these will be translated to path-separators on the platform used during execution-time.

Wildcards

The utility uses three different wildcards.

+----------+-----------------------------------+
| Wildcard |            Description            |
+----------+-----------------------------------+
| *        | Matches zero or more characters.  |
| ?        | Matches exactly one character.    |
| **       | Matches zero or more directories. |
