mybits-plus插入数据后如何得到自增id

数据库插入成功后，mybits-plus会自动回写对象中的id属性，如下面代码：BillTask对象保存后，可以直接通过billTask.getId()获取到自增id

  1. @Override
  2. @RequestMapping(value = "/save", method = RequestMethod.POST)
  3. @ResponseBody
  4. public ApiResult save(@RequestBody BillTask billTask) {
  5.     LocalDateTime now = LocalDateTime.now();
  6.     billTask.setCreatedAt(now);
  7.     billTask.setUpdatedAt(now);
  8.     int id = this.billTaskService.saveOne(billTask);
  9.     System.out.println("Id："+billTask.getId());
  10.     return ApiResultUtil.ok("保存成功");
  11. }
