Trailing slash was added while posting to service context path

There are two services, service A and service B.

in Service B, its context path is member and there is a controller defined as follow

@Contoller
public MemberController {
    @PostMapping
    public Member saveMember(Member member){
    }
}

and in Service A, a Feign client is defined to call this endpoint

@FeignClient(name = "service-b", path = "member")
public MemberFeignClient {
    @PostMapping
    public Member saveMember(Member member);
}

While executing the code, feign client print log with location calling to http://service-b/member/, which a trailing slash was added. I tried to add config from code or autoconfig to remove it but it was still added.

As Spring is no longer support trailing slash, it threw error as the path not found.

Version:
Spring Cloud OpenFeign: 5.0.1

Reproduce the request using the Service A Feign client and Service B controller shown in the issue, then trace how @FeignClient(path = "member") and @PostMapping combine into the request URL. Done when the generated POST target omits the trailing slash and a regression test covers this context-path case.
