我正试图在spring boot+thymeleaf中开发一个应用程序，我能够从mysql数据库的profile选项卡中检索登录用户的详细信息，但是，当我尝试更改一个或两个字段详细信息（更新）并点击更新按钮时，会显示一条错误消息-fri sep 04 20:39:47 ist 2020出现意外错误（type=method not allowed，status=405）。不支持请求方法“post”
查看我的控制器代码（我在类的顶部使用@restcontroller注解）-

@RequestMapping(value = "/profile", method = RequestMethod.PUT)
    public ModelAndView updateProfile(@ModelAttribute Customer customer, HttpSession session) {

        ModelAndView model = new ModelAndView();

        Customer exist = cRepo.findByCustEmail(customer.getCustEmail());

        if(exist != null) {
            if(exist.getCustEmail().equals(session.getAttribute("emailsession"))) {

                cRepo.save(customer);
                model.addObject("msg", "User Details has been successfully updated!!");
                model.setViewName("profile");
            }

        }else {

            model.addObject("exist", "Please enter correct email address!");
            String email = (String) session.getAttribute("emailsession");
            Customer cust = cRepo.findByCustEmail(email);
            model.addObject("customer", cust);
            model.setViewName("profile");

        }

        return model;
    }

文件页代码（html）-

<div align="center" class="alert alert-danger" th:if="${exist}" th:utext="${exist}"></div>

我想当用户登录和访问他/她应该能够检查他/她的个人资料（我可以做工作代码），当用户想更新几个字段（1-2根据选择）和点击更新，他/她应该能够更新的细节（不创建新的用户或记录），因为当我使用@controller类的顶部，然后这个代码的工作和创建新用户改为更新。
