netflix feign issue with query parameters

I am using feign client for some discovery and request.

I am using query parameter in my request

if I hard code like below it works.

@FeignClient("userdetailservice")
public interface UserServiceClient {
@RequestMapping(
            method= RequestMethod.GET,
            value = "/alluser/getmyuser?user=1234")
    String getUserDetails();
    }

But this one does not work, it sending request as 'POST' though I mentioned as GET. Its very strange.

@FeignClient("userdetailservice")
public interface UserServiceClient {
@RequestMapping(
            method= RequestMethod.GET,
            value = "/alluser/getmyuser?user={userid}")
    String getUserDetails(@Param(value = "userid") String userid);
    }

So how to send a query parameters in Feign request.

Solution

  • All Query parameters will automatically be extracted from the url by a split using the & character and mapped to the corresponding @RequestParam in the method declaration.

    So you don't need to specify all the keys the @RequestMapping annotation and there you should only specify the endpoint value.
