哪个 OpenFeign 客户端标头有效？

如何解决哪个 OpenFeign 客户端标头有效？

在下面的代码中，唯一包含的头是 D.. 我想包含的标题是静态的，所以我宁愿使用其他方法之一！有什么想法吗？

import feign.Headers;
import feign.Response;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

@RefreshScope
@Headers("A: a")
public interface FeignClientX {

    @Headers("B: b")
    @RequestMapping(value = "/api/",method = RequestMethod.GET,headers = "C: c")
    Response getFee(@RequestHeader("D") String token);
}

日志：
