A page written by bootstrap:

:

:

this is the background code:

@PostMapping(value = "forgetPassword", produces = "application/json;charset=utf-8")
    @ResponseBody
    public String forgetPassword(@RequestParam("email") String email) {
            return null;
    }

this is an error report in the background:

 [http-nio-8090-exec-8] org.springframework.web.servlet.PageNotFound.
handleHttpRequestMethodNotSupported Request method "GET" not supported

excuse me, why is this? I clearly requested user/forgetPassword, but the error message pointed to login.html (the interface for entering the mailbox is a pop-up of a tag on login.html)
