使用UserDetailsService不能创Remember me cookie

我似乎找不到配置上的问题,为什么没有生成remember-me cookie。唯一被创建的cookie是JSESSIONID。我注意到,当我去"/"路径时,未经认证,它已经创建了一个空的内容记住我的cookie。

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/", "/public/**").permitAll()
                .antMatchers("/users/**").hasAuthority("ADMIN")
                .anyRequest().authenticated()

                .and()
                .formLogin()
                .loginPage("/login")
                .failureUrl("/login?error")
                .usernameParameter("e" + "mail")
                .permitAll()

                .and()
                .logout()
                .logoutUrl("/logout")
                .deleteCookies("remember-me")
                .logoutSuccessUrl("/")
                .permitAll()

                .and()
                .rememberMe()
                    .rememberMeCookieName("remember-me");
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .userDetailsService(userDetailsService)
                .passwordEncoder(new BCryptPasswordEncoder());
    }
