springboot导入excel文件信息到数据库（上传或更新）

有校验手机号和邮箱以及其他的枚举校验。可以参考

Controller ：

/**
     * 导入用户数据
     * @param file
     * @return
     */
    @RequestMapping(value = "/import", method = RequestMethod.POST)
    public UserCentreResponse importUser(@RequestPart("file") FilePart file) {
        UserCentreResponse userCentreResponse = new UserCentreResponse();
        List<String> errorList = new ArrayList<>();
        String fileName = null;
        if (file != null) {
            fileName = file.filename();//getOriginalFilename();

            try {
                errorList = userService.batchImport(fileName, file);
            } catch (Exception e) {
                log.error(e.getMessage(), e);
            }
            userCentreResponse.setValue("导入成功！", errorList);
            return userCentreResponse;
        }else {
            return userCentreResponse.setError(400, "请导入文件！");
        }
    }
