成品网站代理seo优化的作用
一、概述
基于Spring Cloud微服务架构,通过Gateway网关、OAuth2协议和JWT令牌实现分布式系统的单点登录,允许用户一次登录后访问所有互信的微服务。核心技术组件包括:
- Spring Cloud Gateway:统一请求入口,负责路由、Token验证和转发
- OAuth2协议:定义授权流程,实现用户认证和授权码交换
- JWT(Json Web Token):作为无状态令牌载体,包含用户身份和权限信息
二、系统架构与服务组件
1. 服务架构图

2. 服务职责说明
服务名称 | 职责描述 |
---|---|
认证中心 | 处理用户登录、生成JWT令牌、管理客户端注册信息,作为OAuth2授权服务器 |
API网关 | 统一请求入口,实现路由分发、Token验证与传递,集成OAuth2客户端配置 |
资源服务 | 提供业务数据接口(如用户、订单服务),验证Token并基于权限控制访问 |
客户端应用 | 用户交互入口,引导登录、获取Token并调用资源服务,展示业务数据 |
三、核心技术实现
