Java 学习 Ant 路径样式

Learning Ant path style

提问by MDK

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

在哪里可以找到学习Ant 路径样式约定的资源？我已经访问了 Ant 站点本身，但找不到有关路径样式的任何信息。

I suppose you mean how to use path patterns

我想你的意思是如何使用路径模式

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

如果是关于使用斜杠还是反斜杠，这些将被转换为执行时使用的平台上的路径分隔符。

Ant-style path patterns matching in spring-framework:

spring-framework 中的Ant 样式路径模式匹配：

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.jspor com/txst.jsp
• com/*.jsp- matches all .jspfiles in the comdirectory
• com/**/test.jsp- matches all test.jspfiles underneath the compath
• org/springframework/**/*.jsp- matches all .jspfiles underneath the org/springframework path
• org/**/servlet/bla.jsp- matches org/springframework/servlet/bla.jspbut also org/springframework/testing/servlet/bla.jspand org/servlet/bla.jsp
• com/{filename:\\w+}.jspwill match com/test.jspand assign the value testto the filenamevariable

映射使用以下规则匹配 URL：

• ?匹配一个字符
• *匹配零个或多个字符
• **匹配路径中的零个或多个“目录”
• {spring:[a-z]+}匹配正则表达式[a-z]+作为名为“spring”的路径变量

一些例子：

• com/t?st.jsp- 匹配 com/test.jsp 但也匹配com/tast.jsp或com/txst.jsp
• com/*.jsp- 匹配目录中的所有.jsp文件com
• com/**/test.jsp- 匹配路径test.jsp下的所有文件com
• org/springframework/**/*.jsp- 匹配.jsp下面的所有文件org/springframework path
• org/**/servlet/bla.jsp- 匹配org/springframework/servlet/bla.jsp但也org/springframework/testing/servlet/bla.jsp和org/servlet/bla.jsp
• com/{filename:\\w+}.jsp将匹配com/test.jsp和的值分配test给filename变量

As @user11153 mentioned, Spring's AntPathMatcherimplements and documents the basics of Ant-style path pattern matching.

正如@user11153 提到的，Spring 的AntPathMatcher实现并记录了 Ant 样式路径模式匹配的基础知识。

In addition, Java 7's nio APIs added some built in support for basic pattern matching via FileSystem.getPathMatcher

此外，Java 7 的 nio API 通过FileSystem.getPathMatcher添加了一些对基本模式匹配的内置支持
