Spring UriComponentsBuilder doesn't encode + in the query param value

UriComponentsBuilder doesn't encode + in the value .. here is the test which it fails

UriComponents components = UriComponentsBuilder.fromHttpUrl("http://localhost/path")
                .queryParam("p","{v}")
                .buildAndExpand("a+b=")
                .encode();
assertEquals("p=a%2Bb%3D", components.getQuery());

Expected :p=a%2Bb%3D Actual :p=a+b%3D

Affects: org.springframework:spring-web:5.3.18

Closing as invalid as this has been done on purpose in #23025, see this comment in particular and the reference documentation on URI encoding.

@bclozel - Thank you! I also got the usage of RestTemplate from above thread.
