Trailing slash was added while posting to service context path

[simonlkh]

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

I figured out what's happened in my issue.
Servlet would redirect POST call without trailing slashto context path with a GET call. I believe that's why OpenFeign adding trailing slash by default if it is making POST call to context path.
And unfortunately in my Spring Boot UrlHandlerFilter, it was mis-configured and context path was excluded from the trailing slash handling pattern.
It was returning 302 in the case that misled me that was OpenFeign issue.

Please help to close this issue as I think everything was fine. Just some mis-configuration and misunderstanding.
