详解Spring mvc ant path的使用方法
概要：
任何一个WEB都需要解决URL与请求处理器之间的映射，spring MVC也是一样，但Spring MVC就像Spring所作的一切一样(灵活，可以配置各种东西，但是也造成了很多复杂性)，肯定不会只有一种方法来映射URL和 Controller之间的关系，并且在实际上，允许你自己创建映射规则和实现，而不仅仅依赖URL映射。
1、Spring path match
Spring MVC中的路径匹配要比标准的web.xml要灵活的多。默认的策略实现了 org.springframework.util.AntPathMatcher，就像名字提示的那样，路径模式是使用了Apache Ant的样式路径，Apache Ant样式的路径有三种通配符匹配方法（在下面的表格中列出)这些可以组合出很多种灵活的路径模式。
2、Apache ant type
下面就来描述一下apache ant匹配规则，其实还是挺简单的。
Ant通配符描述
Wildcard
Description
?
匹配任何单字符
*
匹配0或者任意数量的字符
**
匹配0或者更多的目录
3、举例说明：
1、 /views/products/**/*.cfm
# Matches /views/products/index.cfm /views/products/SE10/index.cfm /views/products/SE10/details.cfm /views/products/ST80/index.cfm /views/products/ST80/details.cfm # Does Not Match: /views/index.cfm /views/aboutUs/index.cfm /views/aboutUs/managementTeam.cfm
2、 /views/**/*.cfm
# Matches: /views/index.cfm /views/aboutUs/index.cfm /views/aboutUs/managementTeam.cfm /views/products/index.cfm /views/products/SE10/index.cfm /views/products/SE10/details.cfm /views/products/ST80/index.cfm /views/products/ST80/details.cfm # Does Not Match: /views/index.htm /views/readme.txt
3、 /views/index??.cfm
# Matches: /views/index01.cfm /views/index02.cfm /views/indexAA.cfm # Does Not Match: /views/index01.htm /views/index1.cfm /views/indexA.cfm /views/indexOther.cfm /views/anotherDir/index01.cfm
如果知道这些我们就能够在Spring MVC灵活的配置url映射了。
