詳解Spring mvc ant path的使用方法
概要：
任何一個WEB都需要解決URL與請求處理器之間的映射，spring MVC也是一樣，但Spring MVC就像Spring所作的一切一樣(靈活，可以配置各種東西，但是也造成了很多復(fù)雜性)，肯定不會只有一種方法來映射URL和 Controller之間的關(guān)系，并且在實(shí)際上，允許你自己創(chuàng)建映射規(guī)則和實(shí)現(xiàn)，而不僅僅依賴URL映射。
1、Spring path match
Spring MVC中的路徑匹配要比標(biāo)準(zhǔn)的web.xml要靈活的多。默認(rèn)的策略實(shí)現(xiàn)了 org.springframework.util.AntPathMatcher，就像名字提示的那樣，路徑模式是使用了Apache Ant的樣式路徑，Apache Ant樣式的路徑有三種通配符匹配方法（在下面的表格中列出)這些可以組合出很多種靈活的路徑模式。
2、Apache ant type
下面就來描述一下apache ant匹配規(guī)則，其實(shí)還是挺簡單的。
Ant通配符描述
| Wildcard | Description |
|---|---|
| ? | 匹配任何單字符 |
| * | 匹配0或者任意數(shù)量的字符 |
| ** | 匹配0或者更多的目錄 |
3、舉例說明：
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
如果知道這些我們就能夠在Spring MVC靈活的配置url映射了。
