feign

沒有feign：

public static final String PRODUCT_GET_URL = "http://MICROCLOUD-PROVIDER-PRODUCT/prodcut/get/";

Product product = restTemplate.getForObject(PRODUCT_GET_URL + id,  Product.class);

有了feign 直接注入接口 直接調用

@Resource
private IProductClientService iProductClientService;

Object result =  iProductClientService.getProduct(id);
