我想从Spring云的客户端服务获得响应FeignClint我编写了一个FeignClient接口

@FeignClient(name = "currencyClient", url = "https://example", configuration = FeignConfig.class)
public interface CurrencyClient {
    @RequestLine(value = "GET /{name}/{date}")
    @Headers("Content-Type: application/json")
    Currency getByNameAndDate(@Param String name, @Param LocalDateTime date);
}

但它没有编译，正在发生此错误

您应该尝试注解@PathVariable和@GetMapping

@GetMapping(path = "/{name}/{date}")
    Currency getByNameAndDate(@PathVariable String name, @PathVariable LocalDateTime date);

客户端应按以下方式设置：

public interface CurrencyClient {
    @RequestMapping(method = RequestMethod.GET, value = "/{name}/{date}")
    @Headers("Content-Type: application/json")
    List<Store> getByNameAndDate(@PathVariable("name") String name, @PathVariable("date") Date date);
}
