英文:
Regular expression in spring security context for query
问题
我尝试在我的Spring安全上下文XML中匹配这个URL：
/settings/folder_0+folder_1+folder_2.yaml?tag=test
我尝试了：
<s:intercept-url pattern="/settings/(.)([+]?).yaml?tag=test" access="hasAnyRole('ROLE')"/>
但它不起作用。我无法找出我犯了哪个错误。
有人能帮助我吗？
如果可能的话，我想改进这个正则表达式，以接受不同的格式，比如yaml、json等，以及接受任何标签名称。
谢谢

But it doesn't works. I can't figure out where I made a mistake.
Can someone help me ?
If it's possible I want to improve this regex in order to accept different format like yaml, json, ... and in order to accept any tag name.
Thank you

您的Spring Security上下文XML中的正则表达式存在一些问题。
其次，模式中的问号（?）在正则表达式中也有特殊含义，因此也应该进行转义。
以下是一个经过修订的正则表达式，应该可以匹配您提供的URL：
<intercept-url pattern="/settings/.*\\.(yaml|json)\\?tag=.*" access="hasAnyRole('ROLE')" />
英文:
There are a couple of issues with the regular expression in your Spring Security context XML.
Second, the question mark (?) in the pattern also has a special meaning in regular expressions and should be escaped as well.
Here's a revised regex that should match the URL you provided:
<intercept-url pattern="/settings/.*\\.(yaml|json)\\?tag=.*" access="hasAnyRole('ROLE')" />
