前言

Spring Boot 3已经发布一段时间，网上关于Spring Boot 3的资料不是很多，本着对新技术的热情，学习和研究了大量Spring Boot 3新功能和新特性，感兴趣的同学可以参考Spring官方资料全面详细的新功能/新改进介绍

• Spring版本升级到6.x
• JDK版本至少17+
• …

新特性有很多，本文主要针对OAuth 2.0的集成，如果快速开发自己的认证授权服务、OAuth客户端以及资源服务

本文开发环境介绍

开发依赖	版本
Spring Boot	3.0.2

开发环境端口说明

新建三个服务，分别对应认证授权服务、OAuth客户端以及资源服务

服务	端口
认证授权服务	8080
OAuth客户端服务	8081
资源服务	8082

认证授权服务

演示

• 在浏览器地址栏输入http://127.0.0.1:8081/hello
  
  

  因为配置了多个client，会让用户选择用哪个client进行OAuth登录

• 选择第一个client-id-1
• 跳转到认证授权服务进行登录
• 输入用户名test，密码test
  
• 登录成功后跳转授权页面
  
• 勾选scope确认授权
• 重定向请求
  

以上所有页面都是Spring默认的，真实业务开发会自定义这些页面

OAuth客户端openid演示

• 在浏览器输入http://127.0.0.1:8080/.well-known/openid-configuration

  {"issuer":"http://127.0.0.1:8080","authorization_endpoint":"http://127.0.0.1:8080/oauth2/authorize","token_endpoint":"http://127.0.0.1:8080/oauth2/token","token_endpoint_auth_methods_supported":["client_secret_basic","client_secret_post","client_secret_jwt","private_key_jwt"],"jwks_uri":"http://127.0.0.1:8080/oauth2/jwks","userinfo_endpoint":"http://127.0.0.1:8080/userinfo","response_types_supported":["code"],"grant_types_supported":["authorization_code","client_credentials","refresh_token"],"revocation_endpoint":"http://127.0.0.1:8080/oauth2/revoke","revocation_endpoint_auth_methods_supported":["client_secret_basic","client_secret_post","client_secret_jwt","private_key_jwt"],"introspection_endpoint":"http://127.0.0.1:8080/oauth2/introspect","introspection_endpoint_auth_methods_supported":["client_secret_basic","client_secret_post","client_secret_jwt","private_key_jwt"],"subject_types_supported":["public"],"id_token_signing_alg_values_supported":["RS256"],"scopes_supported":["openid"]}
  

• 如果配置了issuer-uri，启动的时候会调用${issuer-uri}/.well-known/openid-configuration获取provider配置信息，如果issuer-uri配置了path也会替换成/.well-known/openid-configuration
• 从/.well-known/openid-configuration这个接口获取到的user-info-uri地址是http://127.0.0.1:8080/userinfo 所以会从授权服务获取用户信息
• 要想让授权服务的/userinfo接口正常返回，则需要在配置registration时，在scope增加openid，同时scope还需要在profile、email、address、phone中增加至少一个，修改后的yml配置如下

server:
  port: 8081
  servlet:
    session:
      cookie:
        # 需要更换存放sessionId的cookie名字，否则认证服务和客户端的sessionId会相互覆盖
        name: JSESSIONID-2

spring:
  security:
    oauth2:
      client:
        registration:
          client-id-1:
            provider: demo-client-id
            client-id: demo-client-id
            client-secret: demo-client-secret
            authorization-grant-type: authorization_code
            redirect-uri: '{baseUrl}/{action}/oauth2/code/{registrationId}'
#            client-authentication-method: POST
            scope: openid, profile, user_info, pull_requests
            client-name: demo-client-id
          client-id-2:
            provider: demo-client-id2
            client-id: demo-client-id
            client-secret: demo-client-secret
            authorization-grant-type: authorization_code
            redirect-uri: '{baseUrl}/{action}/oauth2/code/{registrationId}'
#            client-authentication-method: POST
            scope: openid, profile, user_info, pull_requests
            client-name: demo-client-id2
        provider:
          demo-client-id:
            issuer-uri: http://127.0.0.1:8080
          demo-client-id2:
            issuer-uri: http://127.0.0.1:8080

• 授权页面会有变化
