        auth.ldapAuthentication()
                .userDnPatterns("uid={0},ou={people}")

    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin();
    }
}

application.properties配置

启动项目后访问localhost:8080

会跳转到被Spring Security提供的登录页面，输入用户名"ben"和密码"benspassword".然后就能继续访问所有的页面，比如localhost:8080/home，会得到如下输出
