【springcloud|springcloud feign传输List的坑及解决】
错误方法1

@RequestMapping(value = "https://www.it610.com/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo(@RequestParam(value = "https://www.it610.com/article/licenseNoList")List licenseNoList);

错误：

feign.FeignException: status 500 reading MerchantStatRemoteApi#getMerchantCompareInfo(List); content

错误方法2

@RequestMapping(value = "https://www.it610.com/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo(@RequestBody List licenseNoList);

错误：

feign.FeignException: status 500 reading MerchantStatRemoteApi#getMerchantCompareInfo(List); content

错误方法3

@RequestMapping(value = "https://www.it610.com/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo(@RequestBody String[] licenseNoList);

服务端的数组是null
正确方法：

@RequestMapping(value = "https://www.it610.com/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)@ResponseBodyMerchantCompareTotalInfo getMerchantCompareInfo(@RequestParam("licenseNoList") String[] licenseNoList);

feign调用传List接不到值改为传数组 List 改为 Long[] 再用Arrays.asList()变成集合
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
