Question

使用Spring Security时，您会将一系列过滤器映射到URL模式，以指定这些URL的安全性。这些模式可以包含通配符，例如

/foo/*/bar
/foo/**/bar

我找不到这些通配符的任何文档，但我的猜测是第一个模式匹配

/foo/baz/bar

但不是

/foo/baz/baz/bar

而第二种模式（/foo/**/bar）将匹配这两种模式

Answer 2

你的假设是正确的。单个通配符*匹配url树的特定级别中的任何内容，而双通配符**匹配任何字符串模式。

所以

/foo/*/bar

会匹配

/foo/abc/bar and /foo/xyz/bar but not /foo/abc/xyz/bar

而

/foo/**/bar

会匹配以上所有内容。
