Spring Security在通过html的modelpage登录时出现错误

我正在使用SpringBoot为我的项目和SpringSecurity在内存h2数据库中进行注册，它运行良好，但当我从引导模式向登录发送登录请求时，它会抛出异常

我要做的是，我发送一个带有userid和密码的登录请求，然后像这样读取身份验证过滤器中的值

@Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
            throws AuthenticationException {
        try {
            UserLoginRequestModel creds = new ObjectMapper().readValue(request.getInputStream(),
                    UserLoginRequestModel.class);
            return getAuthenticationManager().authenticate(
                    new UsernamePasswordAuthenticationToken(creds.getUserid(), creds.getPassword(), new ArrayList<>()));

        } catch (Exception e) {
            throw new RuntimeException(e);
        }

    }

另外，我使用userid作为用户名对用户进行身份验证，并实现findUserbyUsername

@Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException 
        {
            UserEntity details = dataCallback.findByuserid(username);
            if (details == null)
                throw new UsernameNotFoundException("Invalid Username or Password.");
            return new User(details.getUserId(), details.getEncryptedPassword(), true, true, 
            true, true, new ArrayList());
        }

请帮助我，伙计们，我被困在这里太久了，因为我无法在我的项目中取得进展！如果您需要与项目配置相关的任何其他信息，请告诉我。

问题在于从请求到java类的映射，正如您所提到的：

UserLoginRequestModel creds = new ObjectMapper().readValue(request.getInputStream(),
                        UserLoginRequestModel.class);

将其更改为：

Map<String, String> params = new HashMap<>();

Map<String, String[]> parameterMap = request.getParameterMap();
            parameterMap.forEach((key,value) -> { params.put(key, value[0]); });
String json = String.format( "{ \"userid\" : \"%s\", \"password\" : \"%s\" }", parameterMap.get("userid")[0], parameterMap.get("password")[0]);
UserLoginRequestModel creds = new ObjectMapper().readValue(json, UserLoginRequestModel.class);

有点罗嗦，但没有那么神奇和有效：

你能分享你的代码吗？我想在我的想法中运行github链接：一个问题，你在baeldung上写博客吗？哈哈，你的回复是空的。我正在上传代码，我猜我这么早就给了你回复了。哈哈，你在发送什么？我会检查@eugen，我感谢你的帮助。我还没有检查！我为公司工作，所以我忙于安排在家工作。我明天会亲自测试，我想问你是否愿意和我一起做这个申请？因为我有一个好主意，但我找不到人帮忙。当然，我怎样才能和你联系？

Map<String, String> params = new HashMap<>();

Map<String, String[]> parameterMap = request.getParameterMap();
            parameterMap.forEach((key,value) -> { params.put(key, value[0]); });
String json = String.format( "{ \"userid\" : \"%s\", \"password\" : \"%s\" }", parameterMap.get("userid")[0], parameterMap.get("password")[0]);
UserLoginRequestModel creds = new ObjectMapper().readValue(json, UserLoginRequestModel.class);
