详解Spring mvc ant path的使用方法
详解Springmvcantpath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,springMVC也是一样,但SpringMVC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、Springpathmatch
SpringMVC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ApacheAnt的样式路径,ApacheAnt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、Apacheanttype
下面就来描述一下apacheant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 #DoesNotMatch: /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 #DoesNotMatch: /views/index.htm /views/readme.txt
3、/views/index??.cfm
#Matches: /views/index01.cfm /views/index02.cfm /views/indexAA.cfm #DoesNotMatch: /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SpringMVC灵活的配置url映射了。
