springcloud feign傳輸List的坑

無法直接傳輸List

錯誤方法1：

    @RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)
    @ResponseBody
    MerchantCompareTotalInfo getMerchantCompareInfo(
            @RequestParam(value = "licenseNoList")
            List<String> licenseNoList);

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

 

錯誤方法2：

   @RequestMapping(value = "/stat/merchant/get_merchant_compare_info", method = RequestMethod.POST)
    @ResponseBody
    MerchantCompareTotalInfo getMerchantCompareInfo(@RequestBody List<String> licenseNoList);

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

 

錯誤方法3：

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

服務端的數組是null

 

正確方法：

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