Review path matching options and defaults in the new path matching algorithms [SPR-14993]

[spring-projects-issues]

Rob Winch opened SPR-14993 and commented

We should review options and defaults we would like to have as part of the new path matching refinements work under #19112. Especially on the reactive side we can choose different defaults and there be an opportunity to do that for existing code if the switch (from AntPathMatcher to the new one) is explicit.

For example, does the pattern /foo match /foo, /foo/, /foo.html, / foo.

As part of this we should also consider default options for the strategy for determining what the path that is being matched on is, i.e. HttpRequestPathHelper in terms of normalizing the path by removing .., ., path parameters (i.e. semi-colon content), etc.

This has been resolved by the related issues linked in this one.

Quick summary of those changes:

• With Favor query parameters for content negotiation in WebFlux [SPR-15639] #20198, we now favor query parameters instead of path file extensions for alternate ways of dealing with content type negotiation (which should focus on the accept/content-type headers first)
• With Use undecoded path for request mapping in WebFlux [SPR-15640] #20199, the matching process of a request path against a path pattern is now done on the undecoded request path
• and with Replace ParsingPathMatcher with PathPattern registry [SPR-15608] #20167, the suffix matching options are now gone and the only remaining matching options at the handler mapping level are: case sensitive matching and trailing slash match
