Spring Cloud 服務A通過feign呼叫服務B;之前是好好的，但今天突然就不好了，拋以下異常

服務A中定義的feign介面如下：
/** * @author zhangboqing * @date 2018/11/2 * * 商品相關的服務介面 * */ //定義一個feign介面，通過@ FeignClient（“服務名”），來指定呼叫哪個服務 //@FeignClient(value = "common-wx",fallback = XcautoCommonWXApiHystric.class) @FeignClient(name = "merchant-backend",fallback = XcautoMerchantBackendGoodsApiHystric.class) @Component public interface XcautoMerchantBackendGoodsApiService { /** * 商品出庫介面 * @param deliverySaleDTO * @return */ @PostMapping(value = "/goods/delivery/sale/v1") public Object saleGoods(@RequestBody DeliverySaleDTO deliverySaleDTO); }
二、解決方法：
在呼叫方介面方法，指定消費型別就可以了。
將 @PostMapping(value = "/goods/delivery/sale/v1")
替換為：@PostMapping(value = "/goods/delivery/sale/v1",consumes = MediaType.APPLICATION_JSON_VALUE)
