Oauth2覆盖AuthenticationFailurehandler返回的响应

Question

我希望我的authserver在身份验证失败时响应401 http代码。但是，当我在Formlogin配置中添加SimpleUrlAuthenticationFailureHandler时，响应将被OAuth2覆盖。

所以，我的问题是如何避免这种情况，为什么？

我的formlogin安全性和IAuthorizationServer的配置如下

http.requestMatchers()
                .antMatchers("/login", "/oauth/authorize")
                .and()
                .authorizeRequests()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .failureHandler(new SimpleUrlAuthenticationFailureHandler())
                .permitAll()
                .and().csrf().disable()
                .logout().logoutUrl("/logout").logoutSuccessUrl("/");

    @Override
    public void configure(
            AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("clientId")
                .secret(passwordEncoder.encode("secret"))
                .authorizedGrantTypes("authorization_code")
                .scopes("user_info")
                .autoApprove(true);
    }

<oauth>
<error_description>
Full authentication is required to access this resource
</error_description>
<error>unauthorized</error>
</oauth>

此响应实际上是来自OAuth2的响应。
