1.报错场景

前端POST表单提交，后台服务报错 Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported

2.解决方法
application/x-www-form-urlencoded;charset=UTF-8 是以键值对拼接的形式，如 name=abc&phone=123456，并不是application/json那样的json格式{"name":"abc","phone":"123456"}

所以做以下修改：

将原本的接收形式@RequestBody改成@RequestParam，同时用Map来接收参数。

原代码示例:

  @PostMapping("/checkInvoiceInfo")
    public Response checkInvoiceInfo(@RequestBody CheckInvoiceInfoReqDTO checkInvoiceInfoReqDTO) {
        return receiptService.checkInvoiceInfo(checkInvoiceInfoReqDTO);
    }

修改后：

   @PostMapping("/checkInvoiceInfo")
    public Response checkInvoiceInfo(@RequestParam Map<String, String> params) {
        log.info("checkInvoiceInfo接口params入参：" + params);
        String checkInvoiceTitle = params.get("checkInvoiceTitle");
        String invoiceTitle = params.get("invoiceTitle");
        String checkDealerName = params.get("checkDealerName");
        String dealerName = params.get("dealerName");
        CheckInvoiceInfoReqDTO build = CheckInvoiceInfoReqDTO.builder().checkInvoiceTitle(checkInvoiceTitle).invoiceTitle(invoiceTitle)
                .checkDealerName(checkDealerName).dealerName(dealerName).build();
        return receiptService.checkInvoiceInfo(build);
    }
