+# 营收平台 SSO 单点登录 + 应用接入管理系统
+
+## 功能概述
+
+本系统实现了完整的SSO单点登录和第三方应用接入管理功能，包括：
+
+- OAuth2.0授权框架
+- JWT Token认证
+- 第三方应用注册管理
+- 用户会话管理
+- 权限控制
+- 审计日志
+
+## 核心组件
+
+### 1. SsoService
+SSO服务核心类，提供单点登录、Token验证、应用注册等核心功能。
+
+### 2. OAuth2Controller
+OAuth2.0标准接口控制器，支持多种授权模式：
+- 客户端凭证模式 (client_credentials)
+- 授权码模式 (authorization_code)
+- 密码模式 (password)
+
+### 3. SsoController
+SSO专用接口，提供登录、验证、登出等功能。
+
+### 4. OAuth2Config & OAuth2AuthorizationServerConfig
+OAuth2.0配置类，配置授权服务器设置。
+
+## 数据库表结构
+
+### sso_token - SSO令牌表
+- id: 主键
+- user_id: 用户ID
+- username: 用户名
+- token: JWT令牌
+- create_time: 创建时间
+- expire_time: 过期时间
+- status: 状态 (1:有效, 0:失效)
+- last_use_time: 最后使用时间
+
+### app_registry - 应用注册表
+- id: 主键
+- app_name: 应用名称
+- app_key: 应用密钥
+- app_secret: 应用密钥
+- redirect_uri: 回调地址
+- description: 描述
+- status: 状态
+- create_time: 创建时间
+- admin_user: 管理员用户
+
+### sso_access_log - SSO访问日志表
+- id: 主键
+- user_id: 用户ID
+- username: 用户名
+- app_name: 应用名称
+- action: 操作类型
+- ip_address: IP地址
+- status: 状态
+- create_time: 创建时间
+
+### refresh_token - Token刷新记录表
+- id: 主键
+- user_id: 用户ID
+- username: 用户名
+- access_token: 访问令牌
+- refresh_token: 刷新令牌
+- client_id: 客户端ID
+- scope: 作用域
+- expire_time: 过期时间
+- is_revoked: 是否撤销
+
+## API 接口
+
+### SSO登录接口
+```http
+POST /api/sso/login
+Content-Type: application/json
+
+{
+  "username": "用户名",
+  "password": "密码",
+  "appType": "应用类型"
+}
+```
+
+### Token验证接口
+```http
+POST /api/sso/validate
+Content-Type: application/json
+
+{
+  "ssoToken": "令牌"
+}
+```
+
+### 应用注册接口
+```http
+POST /api/sso/app/register
+Content-Type: application/json
+
+{
+  "appName": "应用名称",
+  "appKey": "应用密钥",
+  "appSecret": "应用密钥",
+  "redirectUri": "回调地址",
+  "description": "应用描述"
+}
+```
+
+### OAuth2 Token接口
+```http
+POST /oauth2/token
+Content-Type: application/x-www-form-urlencoded
+
+grant_type=client_credentials&client_id=客户端ID&client_secret=客户端密钥
+```
+
+## 使用流程
+
+### 1. 第三方应用接入流程
+1. 应用管理员调用应用注册接口获取appKey和appSecret
+2. 应用使用appKey和appSecret进行身份验证
+3. 应用获取用户授权后，通过OAuth2流程获取访问令牌
+4. 使用访问令牌调用受保护的API
+
+### 2. 用户单点登录流程
+1. 用户在任意应用中使用用户名密码登录
+2. 系统生成SSO令牌并返回给客户端
+3. 客户端存储令牌用于后续API调用
+4. 令牌过期时，用户需要重新登录
+
+### 3. 权限验证流程
+1. 客户端在每个API请求中携带访问令牌
+2. 服务端验证令牌有效性
+3. 检查用户对特定资源的访问权限
+4. 允许或拒绝访问请求
+
+## 配置说明
+
+### application.yml 配置
+```yaml
+sso:
+  token:
+    timeout: 3600  # Token过期时间（秒）
+    refresh-enabled: true
+    refresh-interval: 300
+  security:
+    enable-csrf: true
+    enable-cors: true
+    cors:
+      allowed-origins: ["http://localhost:3000", "http://localhost:8080"]
+      allowed-methods: ["GET", "POST", "PUT", "DELETE", "OPTIONS"]
+      allowed-headers: ["*"]
+```
+
+### 数据库配置
+确保数据库中包含SSO相关的表结构，可通过执行以下SQL创建：
+```sql
+-- 在wm-revenue/src/main/resources/db/V3__sso_tables.sql中定义
+```
+
+## 安全注意事项
+
+1. **Token安全**：所有令牌都使用JWT格式，包含签名验证
+2. **密码安全**：用户密码使用BCrypt加密存储
+3. **应用密钥安全**：应用密钥需妥善保管，避免泄露
+4. **审计日志**：所有重要操作都有完整的审计日志记录
+5. **Token过期**：定期清理过期令牌，确保系统性能
+
+## 部署说明
+
+1. 确保数据库连接正常
+2. 执行数据库初始化脚本创建SSO相关表
+3. 配置application.yml中的相关参数
+4. 启动服务并测试各接口功能
+
+## 故障排查
+
+### 常见问题
+1. **Token验证失败**：检查Token是否过期，签名是否正确
+2. **应用注册失败**：检查应用名称是否重复，参数是否完整
+3. **数据库连接失败**：检查数据库配置和网络连接
+
+### 调试建议
+1. 启用DEBUG级别日志查看详细错误信息
+2. 使用Postman等工具测试接口
+3. 检查数据库表结构和数据完整性
+
+## 更新日志
+
+### v1.0.0
+- 实现基础SSO单点登录功能
+- 支持OAuth2.0授权框架
+- 实现第三方应用注册管理
+- 添加完整的审计日志记录
