SpringBoot——String字符串格式化爲LocalDate

 @PostMapping("/edit")
    public String edit(Long id, String name, @RequestParam @DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate birthday) {

        System.out.println(birthday);
        Customer customer = customerService.getById(id);
        customer.setBirthday(birthday);
        customer.setName(name);
        boolean b = customerService.updateById(customer);
        if (b) {
            return "redirect:/customer/list";
        }
        return null;
    }
