Spring boot Request Mapping URI Patterns

Question

There is a request mapping like this:

@DeleteMapping(value = "/{version:.+}")

I not sure what is the .+ does, but from what i know, this delete mapping can accept a value and match to path variable version , something like:

DELETE
/abc

Value abc will map to path variable version

Why the .+ is needed?

Edited Question: What is the difference with just /{version} , is there any special case that requires .+ ?

@DeleteMapping(value = "/{version:.+}")

.+ means "one or more of any characters" - thats standard regex/

version: means - put that match in path variable named version.
