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。
