'+'(Plus sign) interpreted as a ' ' (space) when using RestTemplate

[morDevelop]

Hi,
I'm using Spring version: 5.0.6.RELEASE.
I have exactly the same issue as described here: Stackoverflow#54294843

I'm sending the following GET request using the RestTemplate:
GET http://localhost:9092/sites/?email=test+f@gmail.com
When I'm using RestTemplate in attempt to send the request above,
test+f@gmail.com is being interpreted astest f@gmail.com ('+' interpreted as ' ')

I'm looking for a solution that doesn't involve workarounds.

Bests.

Hello @morDevelop

See this part of the reference documentation for the full picture.

See this particular issue for a similar case and this other issue which improves things.

In your particular case, you could go:

URI uri = UriComponentBuilder.fromHttpUrl("http://localhost:9092/sites/")
    .queryParam("email", "{email}").encode().buildAndExpand("test+f@gmail.com"); 

Feel free to submit a better answer to this question on StackOverflow.

Thanks!
