@wonwoo this is a Long attribute so naming it user doesn't feel right. That really is the user identifier, hence the current code is better. Thanks for the PR, in any case.

I think this example is wrong.
Cannot resolve path variable user

@GetMapping("/{user}") 

from

@GetMapping("/{userId}") 

What do you think?

[snicoll]

Thanks for the follow-up. You are right that the mapping is wrong, I overlooked that, sorry.

I don't think that we should rename the variables as I find them a bit confusing. Rather I'd rename the path variable pattern to use {userId} rather than `{user}. Would you be willing to update your PR in that direction?

[wonwoo]

please review again!
thank!
