String method for PatternsRequestCondition#getMatchingCondition [SPR-11484]

[spring-projects-issues]

Christopher Smith opened SPR-11484 and commented

Spring HATEOAS provides a number of convenient reflective methods that will construct a resource URI by inspecting the controller handling a given resource type. I am trying to work on the reverse issue (finding the controller method that matches a particular URI), and the information I need appears to be in RequestMappingHandlerMapping, particularly in the composite PatternsRequestCondition.

However, PatternsRequestCondition only implements the interface getMatchingCondition, which requires an HttpServletRequest. Internally, it immediately extracts the path information from the request and inspects patterns for matches based on that string. It would be helpful for reflection tools to be able to call this method with just a String object, and it would be trivial to Extract Method on getMatchingCondition to add a getMatchingCondition(String) variant.

Spring MVC does as well. Perhaps you've seen MvcUriComponentsBuilder (inspired by the Spring HATEOAS link builder).

I've added a getMatchingPatterns method that returns a collection of sorted, matching patterns. Hopefully that meets your needs. See the commit 801237aec1aba0a2fb8d666fa2d0313dac4aa3aa.
