When to choose @RequestParam over @PathVariable and vice-versa?

Question

I know what @RequestParam does and what @PathVariable does on an individual note but my question is when building a URL, when should I go for @RequestParam and when for @PathVariable? What are the pros and and cons of using both these annotations?

I did go through this link When to go for @RequestParam and @PathVariable but did not get a satisfactory answer anywhere.

Answer 1

@PathVariable identifies the pattern that is used in the URI for the incoming request.

Query args (@RequestParam) are used on querying/searching resources exclusively. They contain data that affects the query.

Here are some tips for creating good URLs.

Answer 2

It makes more sense to use @Pathvariable to give the user an idea of what the page means.
twitter.com/{userid}
@RequestParamscan be used to get info as parameter, like twitter.com?search=%23yolo
@Pathvariable will help the user navigate or directly move to certain views/pages.
