邮递员使用具有相同键的多个查询参数获取请求返回空列表

Question

I am trying to get a list value of all of my product which corresponds to my research criteria, in my case research criteria are their references and their region by using Postman (GET METHOD):

https://localhost/services/choices/?ref=test1&ref=test2&region=west

But whenever I try to get my references in my code, I receive a list with zero size.

@Path("/choices")
@GET
@Produces(MediaType.APPLICATION_JSON)
@ApiOperation(value = "get products")
@ApiResponses(value = {@ApiResponse(code=200,message = "Success"),
        @ApiResponse(code=500, message = "Server error")
})
public Response getProduct(@QueryParam("ref") final List<String> ref,
                           @QueryParam("region") final String region,
                          @Context final HttpServletRequest request){
    LOGGER.info("Call for references {} and region {}",ref,region);
    try{


        return Response.ok(productBusinessService.getProducts(ref,region)).build();

    }catch (Exception e){

        throw new InternalServerErrorHttpException("Technical Error", e.getMessage(), e);
    }finally {
        LOGGER.info("End of the Call for references {} and region {}",ref,region);
    }
}

My question is : Is it possible to pass multiple query parameters with the same key name in postman,if yes why do I receive empty list while I get the value of region

实际上，我必须重新启动我的邮递员客户端才能使其工作，因此重新启动客户端可以作为解决方案
