通过 Spring Cloud Gateway 访问认证中心进行认证并获取得到访问令牌。
再根据访问令牌 access_token 获取当前登录的用户信息。
前言
Spring Security OAuth2 的最终版本是2.5.2，并于2022年6月5日正式宣布停止维护。Spring 官方为此推出了新的替代产品，即 Spring Authorization Server。然而，出于安全考虑，Spring Authorization Server 不再支持密码模式，因为密码模式要求客户端直接处理用户的密码。但对于受信任的第一方系统(自有APP和管理系统等)，许多情况下需要使用密码模式。在这种情况下，需要在 Spring Authorization Server 的基础上扩展密码模式的支持。本文基于开源微服务商城项目 youlai-mall、Spring Boot 3 和 Spring Authorization Server 1.1 版本，演示了如何扩展密码模式，以及如何将其应用于 Spring Cloud 微服务实战。
数据库初始化
Spring Authorization Server 官方提供的授权服务器示例 demo-authorizationserver 初始化数据库所使用的3个SQL脚本路径如下：
根据路径找到3张表的SQL脚本
令牌发放记录表: oauth2-authorization-schema.sql
授权记录表: oauth2-authorization-consent-schema.sql
客户端信息表: oauth2-registered-client-schema.sql
整合后的完整数据库 SQL 脚本如下：
-- ---------------------------- -- 1. 创建数据库 -- ---------------------------- CREATE DATABASE IF NOT EXISTS oauth2_server DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci; -- ---------------------------- -- 2. 创建表 -- ---------------------------- use oauth2_server; SET NAMES utf8mb4; SET FOREIGN_KEY_CHECKS = 0; -- ---------------------------- -- 2.1 oauth2_authorization 令牌发放记录表 -- ---------------------------- CREATE TABLE oauth2_authorization ( id varchar(100) NOT NULL, registered_client_id varchar(100) NOT NULL, principal_name varchar(200) NOT NULL, authorization_grant_type varchar(100) NOT NULL, authorized_scopes varchar(1000) DEFAULT NULL, attributes blob DEFAULT NULL, state varchar(500) DEFAULT NULL, authorization_code_value blob DEFAULT NULL, authorization_code_issued_at timestamp DEFAULT NULL, authorization_code_expires_at timestamp DEFAULT NULL, authorization_code_metadata blob DEFAULT NULL, access_token_value blob DEFAULT NULL, access_token_issued_at timestamp DEFAULT NULL, access_token_expires_at timestamp DEFAULT NULL, access_token_metadata blob DEFAULT NULL, access_token_type varchar(100) DEFAULT NULL, access_token_scopes varchar(1000) DEFAULT NULL, oidc_id_token_value blob DEFAULT NULL, oidc_id_token_issued_at timestamp DEFAULT NULL, oidc_id_token_expires_at timestamp DEFAULT NULL, oidc_id_token_metadata blob DEFAULT NULL, refresh_token_value blob DEFAULT NULL, refresh_token_issued_at timestamp DEFAULT NULL, refresh_token_expires_at timestamp DEFAULT NULL, refresh_token_metadata blob DEFAULT NULL, user_code_value blob DEFAULT NULL, user_code_issued_at timestamp DEFAULT NULL, user_code_expires_at timestamp DEFAULT NULL, user_code_metadata blob DEFAULT NULL, device_code_value blob DEFAULT NULL, device_code_issued_at timestamp DEFAULT NULL, device_code_expires_at timestamp DEFAULT NULL, device_code_metadata blob DEFAULT NULL, PRIMARY KEY (id) ); -- ---------------------------- -- 2.2 oauth2_authorization_consent 授权记录表 -- ---------------------------- CREATE TABLE oauth2_authorization_consent ( registered_client_id varchar(100) NOT NULL, principal_name varchar(200) NOT NULL, authorities varchar(1000) NOT NULL, PRIMARY KEY (registered_client_id, principal_name) ); -- ---------------------------- -- 2.3 oauth2-registered-client OAuth2 客户端信息表 -- ---------------------------- CREATE TABLE oauth2_registered_client ( id varchar(100) NOT NULL, client_id varchar(100) NOT NULL, client_id_issued_at timestamp DEFAULT CURRENT_TIMESTAMP NOT NULL, client_secret varchar(200) DEFAULT NULL, client_secret_expires_at timestamp DEFAULT NULL, client_name varchar(200) NOT NULL, client_authentication_methods varchar(1000) NOT NULL, authorization_grant_types varchar(1000) NOT NULL, redirect_uris varchar(1000) DEFAULT NULL, post_logout_redirect_uris varchar(1000) DEFAULT NULL, scopes varchar(1000) NOT NULL, client_settings varchar(2000) NOT NULL, token_settings varchar(2000) NOT NULL, PRIMARY KEY (id) );
授权服务器
youlai-auth 模块作为认证授权服务器
maven 依赖
在 youlai-auth 模块的 pom.xml 添加授权服务器依赖
<!-- Spring Authorization Server 授权服务器依赖 --> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-oauth2-authorization-server</artifactId> <version>1.1.1</version> </dependency>
application.yml
认证中心配置 oauth2_server 数据库连接信息
spring: datasource: type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/oauth2_server?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&autoReconnect=true username: root password: 123456
