配置文件似乎没读到是因为少加了什么

order的配置文件： bootstrap.yml

spring:
  application:
    name: order
  cloud:
    config:
      discovery:
        enabled: true
        service-id: CONFIG

eureka的配置文件：

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
    register-with-eureka: false
  server:
    enable-self-preservation: false
  instance:
    prefer-ip-address: true
spring:
  application:
    name: eureka

下面是product的feign客户端这边我要提供name和value值具体怎么填写，

@FeignClient(name ="",value = "")
public interface ProductClient {
    @GetMapping("/msg")
    String productMsg();
    @PostMapping("/product/listForOrder")
    public List<ProductInfoOutput> list(@RequestBody List<String> productList);
    @PostMapping("/product/decreaseStock")
    public  void decreaseStock(@RequestBody List<DecreaseStockInput> decreaseStockInputList);
}
