+# Kenaito Config Center
+
+基于 Go 重构的配置中心。
+
+## 技术栈
+
+- **后端**: Go + Gin + xorm + MySQL
+- **前端**: Vue 2 + Vite 5 + Element UI 2
+- **客户端**: Go（Java 客户端保留兼容）
+
+## 项目结构
+
+```
+kenaito-conf/
+├── server/          # Go 管理端
+├── web/             # Vue 前端
+├── go-client/       # Go 客户端
+├── java-springboot-client/  # Java Spring Boot 客户端
+└── sql/             # 数据库脚本
+```
+
+## 快速开始
+
+### 1. 初始化数据库
+
+```bash
+mysql -u root -p configcenter < sql/init.sql
+mysql -u root -p configcenter < sql/testdata.sql  # 测试数据
+```
+
+### 2. 启动后端
+
+```bash
+cd server
+# 修改 config.yaml 中的数据库配置
+go run cmd/main.go
+# 或编译后运行
+go build -o bin/server cmd/main.go
+./bin/server -config config.yaml
+```
+
+后端默认监听 `:8080`。
+
+### 3. 启动前端
+
+```bash
+cd web
+npm install
+npm run dev
+```
+
+前端默认监听 `:3000`，自动代理 API 到后端。
+
+### 4. 访问
+
+打开 http://localhost:3000
+
+默认管理员账号：`admin` / 密码为 BCrypt 哈希对应的原始密码（见 testdata.sql）
+
+## Go 客户端使用
+
+```go
+import "kenaito-conf/go-client"
+
+cfg := &client.Config{
+    BaseURL:      "http://localhost:8080",
+    AppName:      "myapp",
+    Env:          "dev",
+    Version:      "latest",
+    SyncInterval: 30,
+    CacheDir:     ".",
+}
+
+c := client.New(cfg)
+
+// 注册变更回调
+c.OnChange(func(changed map[string]string) {
+    for k, v := range changed {
+        fmt.Printf("%s = %s\n", k, v)
+    }
+})
+
+// 启动（拉取全量配置 + 开启定时同步）
+c.Start()
+defer c.Stop()
+
+// 读取配置
+dbHost := c.Get("db.host")
+```
+
+## API 概览
+
+### 管理端 API（需 JWT 认证）
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| POST | /user/login | 登录 |
+| GET | /user/login_user_info | 当前用户信息 |
+| GET | /admin/menus | 菜单 |
+| POST | /admin/config/list | 配置列表 |
+| POST | /admin/config/add | 新增配置 |
+| POST | /admin/config/update | 更新配置 |
+| GET | /admin/config/:id | 配置详情 |
+| POST | /admin/config/delete/:id | 删除配置 |
+| GET | /admin/config/config_histories/:id | 配置历史 |
+| GET | /admin/config/rollback/:id | 回滚配置 |
+| POST | /admin/app/list | 应用列表 |
+| POST | /admin/app/add | 新增应用 |
+| GET | /admin/app/tree | 应用树 |
+| GET | /admin/user/list | 用户列表 |
+| POST | /admin/user/add | 新增用户 |
+| GET | /admin/group/list | 业务组列表 |
+| GET | /admin/profile/list | 环境列表 |
+
+### 客户端 API（无需 JWT）
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| GET | /api/fetch_all_configs | 全量拉取配置 |
+| POST | /api/fetch_changed_configs | 增量拉取变更 |
+| GET | /api/ping | 健康检查 |
+
+## 与原 Java 版的差异
+
+- **去掉了 ZooKeeper**：配置变更通知改为客户端定时轮询
+- **认证方式**：管理端用 JWT，客户端 API 暂开放（可后续加签名验证）
+- **前端**：从 layui 静态页面改为 Vue 2 + Element UI 前后端分离
+- **加密算法**：保持 AES 兼容，Java 客户端可继续使用

+# kenaito-conf-springboot2-client-demo
+
+配置中心客户端示例项目。
+
+## 配置说明
+
+在 `application.properties` 中配置：
+
+```properties
+# 配置中心地址
+kenaito.config.server=http://localhost:8080
+kenaito.config.appName=demo
+kenaito.config.env=dev
+kenaito.config.version=latest
+kenaito.config.profile=dev
+```
+
+## 运行步骤
+
+1. 先安装 kenaito-conf-springboot2-client 到本地 Maven 仓库：
+```bash
+cd E:\SelfDev\Gitea2026\kenaito-conf\kenaito-conf-springboot2-client
+mvn clean install -DskipTests
+```
+
+2. 运行示例项目：
+```bash
+cd E:\SelfDev\Gitea2026\kenaito-springboot-demo
+mvn spring-boot:run
+```
+
+3. 访问测试：
+```bash
+curl http://localhost:8081/
+```
+
+## 配置优先级
+
+远程配置 > 本地配置
+
+在配置中心添加应用 `demo` 的配置后，远程配置会覆盖本地同名配置。

+# kenaito-conf-springboot3-client-demo
+
+配置中心 Spring Boot 3 客户端示例项目。
+
+## 环境要求
+
+- **JDK 17 或更高版本**（Spring Boot 3 最低要求）
+- Maven 3.6+
+
+## 配置说明
+
+在 `application.properties` 中配置：
+
+```properties
+# 配置中心地址
+kenaito.config.server=http://localhost:8080
+kenaito.config.appName=demo
+kenaito.config.env=dev
+kenaito.config.version=latest
+kenaito.config.profile=dev
+```
+
+## 运行步骤
+
+1. 确保已安装 JDK 17+：
+```bash
+java -version
+```
+
+2. 先安装 kenaito-conf-springboot3-client 到本地 Maven 仓库：
+```bash
+cd E:\SelfDev\Gitea2026\kenaito-conf\kenaito-conf-springboot3-client
+mvn clean install -DskipTests
+```
+
+3. 运行示例项目：
+```bash
+cd E:\SelfDev\Gitea2026\kenaito-conf\kenaito-conf-springboot3-client-demo
+mvn spring-boot:run
+```
+
+4. 访问测试：
+```bash
+curl http://localhost:8082/
+```
+
+## 配置优先级
+
+远程配置 > 本地配置
+
+在配置中心添加应用 `demo` 的配置后，远程配置会覆盖本地同名配置。
+
+## 与 Spring Boot 2 Demo 的区别
+
+| 项目 | Spring Boot 版本 | JDK 版本 | 端口 |
+|------|------------------|----------|------|
+| kenaito-conf-springboot2-client-demo | 2.7.18 | 1.8+ | 8081 |
+| kenaito-conf-springboot3-client-demo | 3.2.5 | 17+ | 8082 |
+
+## 注意事项
+
+- 当前环境只有 JDK 11，无法运行此项目
+- 需要安装 JDK 17+ 后才能编译和运行
+- 如果需要在 JDK 11 环境测试，请使用 kenaito-conf-springboot2-client-demo

+
+配置中心 Spring Boot 3 客户端（当前使用 Spring Boot 2.7.18 + JDK 11 编译）
+
+## 重要说明
+
+**当前状态：**
+- 项目名称为 springboot3-client，但实际使用 Spring Boot 2.7.18 + JDK 11 编译
+- 代码已重构，移除了 mendmix 依赖，使用标准 Java/Spring 工具类
+- 为未来升级到 Spring Boot 3 做好准备
+
+**升级到 Spring Boot 3 的步骤：**
+1. 安装 JDK 17 或更高版本
+2. 修改 `pom.xml`：
+   ```xml
+   <maven.compiler.source>17</maven.compiler.source>
+   <maven.compiler.target>17</maven.compiler.target>
+   <spring-boot.version>3.2.5</spring-boot.version>
+   ```
+3. 修改 Spring Framework 版本：
+   ```xml
+   <version>6.1.6</version>
+   ```
+4. 重新编译：`mvn clean install`
+
+## 与 springboot2-client 的区别
+
+1. **移除 mendmix 依赖** - 使用标准 Java/Spring 工具类替代
+2. **使用 Java HttpClient** - 替代 mendmix 的 HttpUtils
+3. **使用 Jackson** - 替代 mendmix 的 JsonUtils
+4. **内置加密工具** - 使用 Java 原生 javax.crypto 实现 AES/DES 加密
+5. **更清晰的代码结构** - 便于维护和扩展
+
+## 配置说明
+
+在 `application.properties` 中配置：
+
+```properties
+# 启用配置中心
+kenaito.config.enabled=true
+
+# 配置中心服务地址（支持多个，逗号分隔）
+kenaito.config.baseUrl=http://localhost:8080
+
+# 应用名称
+kenaito.config.appName=myapp
+
+# 环境标识
+kenaito.config.profile=dev
+
+# 版本号
+kenaito.config.version=latest
+
+# 同步间隔（秒）
+kenaito.config.sync-interval-seconds=60
+
+# 认证 token（如果配置中心启用了认证）
+kenaito.config.token=your-token-here
+```
+
+## 使用方式
+
+### Spring Boot 应用
+
+自动生效，无需额外配置。`KenaitoEnvironmentInitializer` 会在 Spring Boot 启动时自动加载远程配置。
+
+### 传统 Spring 应用
+
+在 Spring 配置文件中添加：
+
+```xml
+<bean class="cn.odboy.confcenter.spring.CCPropertyPlaceholderConfigurer">
+    <property name="remoteEnabled" value="true"/>
+</bean>
+```
+
+## 安装到本地 Maven 仓库
+
+```bash
+mvn clean install -DskipTests
+```
+
+## 依赖说明
+
+- Spring Boot 2.7.18（optional）
+- Spring Context 5.3.31（optional）
+- Jackson 2.17.0（JSON 处理）
+- SLF4J 2.0.12（日志）
+- Java HttpClient（HTTP 请求，JDK 11+ 内置）
+
+## 升级路径
+
+当你的项目升级到 JDK 17 后，可以修改 pom.xml 中的版本配置，切换到 Spring Boot 3：
+
+```xml
+<properties>
+    <maven.compiler.source>17</maven.compiler.source>
+    <maven.compiler.target>17</maven.compiler.target>
+    <spring-boot.version>3.2.5</spring-boot.version>
+</properties>
+
+<dependency>
+    <groupId>org.springframework</groupId>
+    <artifactId>spring-context</artifactId>
+    <version>6.1.6</version>
+</dependency>
+```
