Request method 'GET' not supported

今天做登录和注册的时候出现了这个问题，百度之后说是

即提交的表单字段要与bean的类型完全对应，否则请求并不能完全对应识别。

然后改了程序里面的句子。登录和注册页面要对应起来就可以

这是登录的程序：pass+count.getSalt()原来写的是count.getUser()；

@RequestMapping(value = "login", method = RequestMethod.POST)
public String login(HttpServletResponse response, HttpServletRequest request, @RequestParam("user") String user, @RequestParam("pass") String pass) throws Exception {
    if (user != null && !user.equals("")) {
        Count count = countServiceImpl.selectByName(user);
        if (count.getUser().equals(user)) {
            if (MD5Util.MD5(pass + count.getSalt()).equals(count.getMd5())) {
                Long db = System.currentTimeMillis();
                String df = db.toString();
                String tokenz = user + "," + df;
                String token = EncryUtil.encrypt(tokenz);
                Cookie cookie = new Cookie("name", token);
                //cookie.setDomain("www.hanyaohe.top");
                cookie.setPath("/");
                cookie.setMaxAge(1000 * 60 * 60);
                response.addCookie(cookie);
                return "redirect:/u/one";
            }
        }
    }
    return "redirect:/login";
}

而注册的逻辑写的是：

@RequestMapping(value = "register",method = RequestMethod.POST)
public String register(@RequestParam("user") String user,@RequestParam("pass") String pass,@RequestParam("online") String online,@RequestParam("workers") String workers) throws Exception{
        int check = countServiceImpl.countByName(user);
        if(check>0){
            return "register";
        } else {
            String salt = UUIDUtil.getUUID();
            String MD5 = MD5Util.MD5(pass+salt);
            Count count = new Count();
            count.setPass(pass);
            count.setOnline(online);
            count.setWorkers(user);
            count.setSalt(salt);
            count.setUser(user);
            count.setMd5(MD5);
            countServiceImpl.insert(count);
            return "login";
        }

MD5（是pass+salt），要对应才行。
