简介

整个Spring（SpringBoot）框架的路径解析都是按照Ant的风格来的，比如：Controller的请求路径、文件路径、包的路径。所以，掌握Ant的路径匹配很重要。

Spring中的具体实现： org.springframework.util.AntPathMatcher。其注释里边有解释，翻译成中文如下表：

符号

作用

示例

?

匹配一个字符。

不能匹配目录：这个字符不能是代表路径分隔符的/

/dir/app?

匹配：/dir/app1、/dir/app2

不匹配：/dir/app、/dir/app12、index/

*

匹配0到多个字符。

/dir/app*

匹配：/dir/app、/dir/app1、/dir/app12、/dir/appa/

不匹配：/dir/app/a

**

匹配多级目录。

/dir/**/app*

匹配：/dir/xxx/app* /dir/xxx/yyy/app*

 

/dir/app/**

匹配：dir/app/aa/bcd/e

{spring:[a-z]+}

将正则表达式[a-z]+匹配到的值，赋值给名为 spring 的路径变量。

必须是完全匹配才行，在SpringMVC中只有完全匹配才会进入controller层的方法

@RequestMapping("/index/{username:[a-b]+}")
@ResponseBody
public String index(@PathVariable("username") String username){
    System.out.println(username);
    return username;
}

结果

index/ab           true  输出 ab
index/abbaaa    true  输出 abbaaa
index/a             false 404错误
index/ac            false 404错误

        摘录自Spring的官网测试，不得不说 Spring 的测试用例写的实在是太完善了。 其网址为：https://github.com/spring-projects/spring-framework/blob/main/spring-core/src/test/java/org/springframework/util/AntPathMatcherTests.java

        其测试太长了，本处将其分类。下边这行是公共代码：

private final AntPathMatcher pathMatcher = new AntPathMatcher();
