@FeignClient("hf-user-server")
@RequestMapping("user-api")
public interface UserServiceApi {


    @PostMapping("user-api/code")
    String testApi(@RequestParam(value = "code") String code);

}

但是我把接口层的class的@RequestMapping("user-api")下放到方法上就正常了

/**
 * @author xugm
 */
@FeignClient("hf-user-server")
public interface UserServiceApi {


    @PostMapping("user-api/code")
    String testApi(@RequestParam(value = "code") String code);

}

请问老师怎么解决，谢谢
