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);
