java.lang.illegalstateException：需要UserDetailsservice

Question

最近在学习Spring Boot，几乎是新手。我浏览了一些教程，并一直为我的项目 Spring Boot 工作。 我使用 Remember-me 观看本教程 https://www.youtube.com/watch?v=P_eL5QQmiV0 但似乎我遇到了这个错误

我发现我卡​​了一整天但找不到解决方案

我的配置

@Override
    protected void configure(HttpSecurity http) throws Exception {
        
        http.authorizeRequests()
            .antMatchers("/admin").authenticated()
            .anyRequest().permitAll()
            .and()
            .formLogin()
                .loginPage("/dang-nhap")
                .usernameParameter("emailLogin")
                .passwordParameter("passwordLogin")
                .failureForwardUrl("/login_fail_handler")
                .successForwardUrl("/login_success_handler")
            .and()
            .rememberMe()
                .tokenRepository(persistentTokenRepository())
                .rememberMeCookieName("token-remember-me")
                .tokenValiditySeconds(24*60*60)
            .and()
            .logout()
                .logoutSuccessUrl("/").permitAll()

            ;
                
    }

数据库确实保存了令牌但在重新运行项目后它删除了令牌并显示错误UserDetailsS​​ervice是必需的

我一直在寻找有关此错误的所有 stackoverflow，但似乎所有这些方法都不适合我...
希望你们度过愉快的一天，如果你们愿意的话请帮助我......

要使用表单登录（ daoAuthenticationProvider 在引擎盖下），您必须提供或实现 userDetailsS​​ervice 接口。实现非常容易，因为它只有一种方法。对于探索和学习，您可以提供 inmemoryuserdetailsmanager 作为 @bean ，如下：

    @Bean
    public UserDetailsService userDetailsService() {
        UserDetails user = User.withDefaultPasswordEncoder()
                .username("user")
                .password("password")
                .roles("USER")
                .build();
        UserDetails admin = User.withDefaultPasswordEncoder()
                .username("admin")
                .password("password")
                .roles("ADMIN", "USER")
                .build();
        return new InMemoryUserDetailsManager(user, admin);
    }
