feign传输List的坑

无法直接传输List

错误方法1

				?

									@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)

									@ResponseBody

									MerchantCompareTotalInfo getMerchantCompareInfo(

									  @RequestParam(value = "licenseNoList")

									  List<String> licenseNoList);

错误：

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

错误方法2

				?

									@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)

									@ResponseBody

									MerchantCompareTotalInfo getMerchantCompareInfo(@RequestBody List<String> licenseNoList);

错误：

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

错误方法3

				?

									@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)

									@ResponseBody

									MerchantCompareTotalInfo getMerchantCompareInfo(@RequestBody String[] licenseNoList);

服务端的数组是null

正确方法：

				?

									@RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)

									@ResponseBody

									MerchantCompareTotalInfo getMerchantCompareInfo(@RequestParam("licenseNoList") String[] licenseNoList);
