Can you provide a complete, minimal, verifiable sample that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.

In my case it look like
Send via feign client Preprocess phone=[+123]
Get on recipient Cannot find by phone=[ 123]

Feign Client Send
@RequestMapping(value = "/api/user/user/getUserByUsernamePwd", method = RequestMethod.GET)
public UserDTO getUserByUsernamePwd(
@RequestParam("username")String username,
@RequestParam("password")String password);
username ="aa"
password = “a+123456” [a+123456]

Feign Server Receive
username ="aa"
password = “a 123456” [a 123456]

@ryanjbaxter
I made fork from https://github.com/spring-cloud-samples/feign-eureka and add example with "+".
Commit with current test: https://github.com/mdavydau/feign-eureka/commit/e64c8010ee781a0b45d39839b00724a9679093db
Code example: feign-eureka.zip
Please send on your local env
http://localhost:7211/phone
and check response from server with whitespace
Hello World: 123 | HelloServer:MY_IP:7111

Note: looks like URL encoding issue, I add two cases:
https://github.com/mdavydau/feign-eureka/commit/43db27a16cb7f8972647b4eab411a03f070f4a34
encoded url instead of "+"
http://localhost:7211/phoneplusencoded
and @PathVariable mapping for request
http://localhost:7211/phone/+333
both working well.
