Spring Cloud Gateway 低吞吐量，安全

Posted 2023-02-27

【中文标题】Spring Cloud Gateway 低吞吐量，安全

【英文标题】：Spring cloud gateway low throughput with security

【发布时间】：2021-08-28 07:37:18

【问题描述】：

我想使用基本身份验证来保护我的spring cloud gateway。但是我发现当我添加spring-boot-starter-security依赖和基本配置时，网关在性能测试中吞吐量很差。

具有安全性 - 53.2/秒 没有安全性 - 694.1/秒

怎么了？

安全配置

@EnableWebFluxSecurity
public class SecurityWebFluxConfig 

    @Bean
    public MapReactiveUserDetailsService authentication() 
        UserDetails user = User
                .withUsername("user")
                .password("password")
                .roles("USER")
                .build();
        return new MapReactiveUserDetailsService(user);
    

    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) 
        return http.authorizeExchange()
                .anyExchange().authenticated()
                .and().httpBasic()
                .and().build();
    

【参考方案1】：

您正在观察这一点，因为 Spring Security 利用自适应单向函数来存储密码。这些是故意占用资源的，这意味着为每个请求验证用户名和密码会显着降低应用程序的性能。 Spring Security（或任何其他库）无法加快密码验证速度，因为安全性是通过密集验证资源来获得的。

我鼓励您将长期凭据（即用户名和密码）交换为短期凭据（即会话、OAuth 令牌等），而不是使用 HTTP 基本身份验证。 可以快速验证短期凭证，而不会损失任何安全性。

在 Spring Security 参考文档的Password Storage section 中有对此的深入解释。
