Spring MVC @PathVariable with dot (.) is getting truncated

Question

This is continuation of question Spring MVC @PathVariable getting truncated

Spring forum states that it has fixed(3.2 version) as part of ContentNegotiationManager.

Answer 1

For me the

@GetMapping(path = "/a/{variableName:.+}")

does work but only if you also encode the "dot" in your request url as "%2E" then it works. But requires URL's to all be that...which is not a "standard" encoding, though valid. Feels like something of a bug :|

The other work around, similar to the "trailing slash" way is to move the variable that will have the dot "inline" ex:

@GetMapping(path = "/{variableName}/a")

now all dots will be preserved, no modifications needed.
