feign传输List的坑

无法直接传输列表。

错误方法1@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo( @RequestParam(value = "licenseNoList") Listlt;Stringgt; licenseNoList);

错误:

假装。FeignException: status 500读取MerchantStatRemoteApi # getMerchantCompareInfo(List)；内容

错误方法2@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo(@RequestBody Listlt;Stringgt; licenseNoList);

错误:

假装。FeignException: status 500读取MerchantStatRemoteApi # getMerchantCompareInfo(List)；内容

错误方法3@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo(@RequestBody String[] licenseNoList);

服务器数组为空。

正确方法:

@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo(@RequestParam("licenseNoList") String[] licenseNoList);

feign调用传List接不到值

请改为传递数组ListltLonggt将其更改为Long[]，然后使用Arrays.asList()成为一个集合。

以上个人经验，希望能给你一个参考
