+
+## ⚙️ 配置优先级
+
+系统按以下优先级加载和合并配置：
+
+1. **命令行参数** (最高优先级)
+2. **环境变量**
+3. **配置文件**
+4. **默认值** (最低优先级)
+
+## 🔍 配置发现机制
+
+系统会按以下顺序搜索配置文件：
+
+1. `CONFIG_FILE` 环境变量指定的路径
+2. 当前目录：`config.json`, `jetbrains-ai-proxy.json`
+3. config目录：`config/config.json`, `configs/config.json`
+4. 隐藏目录：`.config/config.json`
+5. 用户主目录：`$HOME/.config/jetbrains-ai-proxy/config.json`
+6. 系统目录：`/etc/jetbrains-ai-proxy/config.json`
+
+如果没有找到配置文件，系统会自动生成示例配置。
+
+## 🚀 使用方式
+
+### 1. 自动配置（推荐）
+
+```bash
+# 生成示例配置
+./jetbrains-ai-proxy --generate-config
+
+# 编辑配置文件
+vim config/config.json
+
+# 启动服务（自动发现配置）
+./jetbrains-ai-proxy
+```
+
+### 2. 使用启动脚本
+
+```bash
+# 智能启动（自动检查配置）
+./start.sh
+
+# 生成配置
+./start.sh --generate
+
+# 查看配置
+./start.sh --config
+```
+
+### 3. 指定配置文件
+
+```bash
+# 使用特定配置文件
+./jetbrains-ai-proxy --config /path/to/config.json
+
+# 或设置环境变量
+export CONFIG_FILE=/path/to/config.json
+./jetbrains-ai-proxy
+```
+
+## 📋 配置文件格式
+
+### JSON配置文件示例
+
+```json
+{
+  "jetbrains_tokens": [
+    {
+      "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+      "name": "Primary_JWT",
+      "description": "Primary JWT token for JetBrains AI",
+      "priority": 1,
+      "metadata": {
+        "environment": "production",
+        "region": "us-east-1"
+      }
+    }
+  ],
+  "bearer_token": "your_bearer_token_here",
+  "load_balance_strategy": "round_robin",
+  "health_check_interval": "30s",
+  "server_port": 8080,
+  "server_host": "0.0.0.0"
+}
+```
+
+### 环境变量配置
+
+```bash
+# JWT Tokens（逗号分隔）
+JWT_TOKENS=token1,token2,token3
+
+# Bearer Token
+BEARER_TOKEN=your_bearer_token
+
+# 负载均衡策略
+LOAD_BALANCE_STRATEGY=round_robin
+
+# 服务器配置
+SERVER_HOST=0.0.0.0
+SERVER_PORT=8080
+
+# 配置文件路径（可选）
+CONFIG_FILE=config/config.json
+```
+
+## 🔄 配置热重载
+
+系统支持运行时配置重载，无需重启服务：
+
+### 自动重载
+
+配置文件监控器会自动检测配置文件变化并重新加载。
+
+### 手动重载
+
+```bash
+# 通过API端点重载
+curl -X POST http://localhost:8080/reload
+
+# 响应
+{
+  "message": "Configuration reloaded successfully"
+}
+```
+
+## 🛠️ 管理端点
+
+系统提供了丰富的管理端点：
+
+| 端点 | 方法 | 描述 |
+|------|------|------|
+| `/health` | GET | 健康检查和负载均衡状态 |
+| `/config` | GET | 当前配置信息（隐藏敏感数据） |
+| `/stats` | GET | 详细统计信息 |
+| `/reload` | POST | 重新加载配置 |
+
+## 🔧 高级功能
+
+### 1. JWT Token元数据
+
+支持为每个JWT token配置元数据：
+
+```json
+{
+  "token": "jwt_token_here",
+  "name": "Production_Primary",
+  "description": "Primary production JWT token",
+  "priority": 1,
+  "metadata": {
+    "environment": "production",
+    "region": "us-east-1",
+    "tier": "primary",
+    "max_requests_per_minute": "1000"
+  }
+}
+```
+
+### 2. 配置验证
+
+系统会自动验证配置的有效性：
+- JWT token格式检查
+- 必需字段验证
+- 数值范围检查
+- 策略有效性验证
+
+### 3. 配置合并策略
+
+多个配置源的合并规则：
+- 数组类型：高优先级完全覆盖低优先级
+- 对象类型：递归合并，高优先级字段覆盖低优先级
+- 基本类型：高优先级直接覆盖低优先级
+
+## 🚨 故障排除
+
+### 配置问题诊断
+
+```bash
+# 查看当前配置
+./jetbrains-ai-proxy --print-config
+
+# 验证配置文件
+./jetbrains-ai-proxy --config config.json --print-config
+
+# 生成新的示例配置
+./jetbrains-ai-proxy --generate-config
+```
+
+### 常见问题
+
+1. **配置文件未找到**
+   - 检查文件路径和权限
+   - 使用 `--generate-config` 生成示例配置
+
+2. **JWT tokens无效**
+   - 检查token格式和有效性
+   - 查看健康检查日志
+
+3. **配置合并问题**
+   - 使用 `--print-config` 查看最终配置
+   - 检查配置优先级
+
+## 📈 性能考虑
+
+1. **配置缓存**: 配置在内存中缓存，避免重复读取
+2. **并发安全**: 使用读写锁保护配置访问
+3. **懒加载**: 配置发现器按需加载配置文件
+4. **监控优化**: 配置文件监控使用高效的文件系统事件
+
+## 🔮 未来扩展
+
+系统设计支持以下扩展：
+- 远程配置中心集成（如Consul、etcd）
+- 配置加密和安全存储
+- 配置版本管理和回滚
+- 更多负载均衡策略
+- 动态配置更新API

+系统支持多种配置方式，优先级从高到低：
+
+1. **命令行参数** (最高优先级)
+2. **环境变量**
+3. **配置文件**
+4. **默认值** (最低优先级)
+
+### 1. 配置文件方式（推荐）
+
+系统会自动搜索以下路径的配置文件：
+
+- `config.json`
+- `config/config.json`
+- `configs/config.json`
+- `.config/jetbrains-ai-proxy.json`
+- `$HOME/.config/jetbrains-ai-proxy/config.json`
+
+配置文件示例：
+
+```json
+{
+  "jetbrains_tokens": [
+    {
+      "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+      "name": "Primary_JWT",
+      "description": "Primary JWT token for JetBrains AI",
+      "priority": 1,
+      "metadata": {
+        "environment": "production",
+        "region": "us-east-1"
+      }
+    },
+    {
+      "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+      "name": "Secondary_JWT",
+      "description": "Secondary JWT token for load balancing",
+      "priority": 2,
+      "metadata": {
+        "environment": "production",
+        "region": "us-west-2"
+      }
+    }
+  ],
+  "bearer_token": "your_bearer_token_here",
+  "load_balance_strategy": "round_robin",
+  "health_check_interval": "30s",
+  "server_port": 8080,
+  "server_host": "0.0.0.0"
+}
+```
+
+### 2. 环境变量配置
+
+```bash
+# 多个JWT tokens，用逗号分隔
+export JWT_TOKENS="jwt_token_1,jwt_token_2,jwt_token_3"
+
+# 或者使用旧的单token配置（向后兼容）
+export JWT_TOKEN="single_jwt_token"
+
+# Bearer token
+export BEARER_TOKEN="your_bearer_token"
+
+# 负载均衡策略（可选，默认为round_robin）
+export LOAD_BALANCE_STRATEGY="random"
+
+# 服务器配置
+export SERVER_HOST="0.0.0.0"
+export SERVER_PORT="8080"
+
+# 指定配置文件路径（可选）
+export CONFIG_FILE="path/to/config.json"
+```
+
+### 3. 命令行参数配置
+
+```bash
+# 查看所有选项
+./jetbrains-ai-proxy --help
+
+# 使用命令行参数启动
+./jetbrains-ai-proxy \
+  -c "jwt1,jwt2,jwt3" \
+  -k "bearer_token" \
+  -s "round_robin" \
+  -p 8080 \
+  -h "0.0.0.0"
+
+# 指定配置文件
+./jetbrains-ai-proxy --config config/my-config.json
+```
+
+## 负载均衡策略
+
+### 轮询策略 (round_robin)
+
+- **默认策略**
+- 按顺序依次使用每个健康的JWT token
+- 确保负载均匀分布
+- 适合大多数场景
+
+### 随机策略 (random)
+
+- 随机选择一个健康的JWT token
+- 避免可预测的请求模式
+- 适合需要随机分布的场景
+
+## 健康检查机制
+
+系统会自动进行JWT token健康检查：
+
+- **检查间隔**: 每30秒检查一次
+- **检查方式**: 发送测试请求到JetBrains AI API
+- **故障处理**: 自动标记失效的tokens为不健康状态
+- **恢复机制**: 定期重新检查不健康的tokens
+
+## 监控端点
+
+访问 `/health` 端点可以查看负载均衡器状态：
+
+```bash
+curl http://localhost:8080/health
+```
+
+响应示例：
+
+```json
+{
+  "status": "ok",
+  "healthy_tokens": 2,
+  "total_tokens": 3,
+  "strategy": "round_robin"
+}
+```
+
+## 使用示例
+
+### 启动服务
+
+```bash
+# 使用3个JWT tokens，轮询策略
+./jetbrains-ai-proxy \
+  -p 8080 \
+  -c "eyJ0eXAiOiJKV1QiLCJhbGc...,eyJ0eXAiOiJKV1QiLCJhbGc...,eyJ0eXAiOiJKV1QiLCJhbGc..." \
+  -k "your_bearer_token" \
+  -s "round_robin"
+```
+
+### 发送请求
+
+```bash
+curl -X POST http://localhost:8080/v1/chat/completions \
+  -H "Authorization: Bearer your_bearer_token" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4o",
+    "messages": [
+      {"role": "user", "content": "Hello, world!"}
+    ],
+    "stream": false
+  }'
+```
+
+## 日志输出
+
+启动时会显示负载均衡器配置信息：
+
+```
+2024/01/01 12:00:00 JWT balancer initialized with 3 tokens, strategy: round_robin
+2024/01/01 12:00:00 JWT health checker started
+2024/01/01 12:00:00 Server starting on 0.0.0.0:8080
+2024/01/01 12:00:00 JWT tokens configured: 3
+2024/01/01 12:00:00 Load balance strategy: round_robin
+```
+
+运行时会显示健康检查和token使用情况：
+
+```
+2024/01/01 12:01:00 Performing JWT health check...
+2024/01/01 12:01:01 Health check completed: 3/3 tokens healthy
+2024/01/01 12:01:30 JWT token marked as unhealthy: eyJ0eXAiOi... (errors: 1)
+2024/01/01 12:02:00 JWT token marked as healthy: eyJ0eXAiOi...
+```
+
+## 故障排除
+
+### 1. 所有tokens都不健康
+
+如果所有JWT tokens都被标记为不健康，请求会返回错误：
+
+```json
+{
+  "error": "no available JWT tokens: no healthy JWT tokens available"
+}
+```
+
+**解决方案**:
+
+- 检查JWT tokens是否有效
+- 检查网络连接
+- 查看健康检查日志
+
+### 2. 部分tokens不健康
+
+系统会自动使用健康的tokens，但建议：
+
+- 检查不健康tokens的有效性
+- 考虑更换失效的tokens
+- 监控健康检查日志
+
+### 3. 性能优化
+
+- 根据实际负载调整JWT tokens数量
+- 选择合适的负载均衡策略
+- 监控 `/health` 端点的响应
+
+## 技术实现
+
+### 核心组件
+
+1. **JWTBalancer**: 负载均衡器接口和实现
+2. **HealthChecker**: JWT健康检查器
+3. **Config**: 配置管理，支持多JWT配置
+4. **Client**: 集成负载均衡器的HTTP客户端
+
+### 并发安全
+
+- 使用读写锁保护共享状态
+- 原子操作处理计数器
+- 线程安全的随机数生成器
+
+### 错误处理
+
+- 自动重试机制
+- 优雅的错误降级
+- 详细的错误日志记录

+  "message": "Configuration reloaded successfully"
+}
+```
+
+## 🧪 测试API
+
+### 发送聊天请求
+
+```bash
+# 发送非流式请求
+curl -X POST http://localhost:8080/v1/chat/completions \
+  -H "Authorization: Bearer your_bearer_token" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4o",
+    "messages": [
+      {"role": "user", "content": "Hello, how are you?"}
+    ],
+    "stream": false
+  }'
+
+# 发送流式请求
+curl -X POST http://localhost:8080/v1/chat/completions \
+  -H "Authorization: Bearer your_bearer_token" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4o",
+    "messages": [
+      {"role": "user", "content": "Tell me a story"}
+    ],
+    "stream": true
+  }'
+```
+
+### 获取支持的模型
+
+```bash
+# 获取模型列表
+curl http://localhost:8080/v1/models \
+  -H "Authorization: Bearer your_bearer_token"
+```
+
+## 🚨 故障排除
+
+### 常见问题
+
+1. **所有JWT tokens都不健康**
+   ```bash
+   # 检查token有效性
+   curl http://localhost:8080/health
+   
+   # 查看日志
+   tail -f /var/log/jetbrains-ai-proxy.log
+   ```
+
+2. **配置文件未找到**
+   ```bash
+   # 生成示例配置
+   ./jetbrains-ai-proxy --generate-config
+   
+   # 检查配置文件路径
+   ./jetbrains-ai-proxy --print-config
+   ```
+
+3. **端口被占用**
+   ```bash
+   # 检查端口使用情况
+   lsof -i :8080
+   
+   # 使用不同端口启动
+   ./jetbrains-ai-proxy -p 9090
+   ```
+
+### 日志分析
+
+```bash
+# 查看实时日志
+tail -f jetbrains-ai-proxy.log
+
+# 过滤健康检查日志
+grep "health check" jetbrains-ai-proxy.log
+
+# 过滤错误日志
+grep -i error jetbrains-ai-proxy.log
+```
+
+## 📈 性能优化建议
+
+1. **JWT Token数量**: 建议配置3-5个JWT tokens以获得最佳负载均衡效果
+2. **健康检查间隔**: 生产环境建议设置为30-60秒
+3. **负载均衡策略**: 
+   - 使用`round_robin`获得均匀分布
+   - 使用`random`避免可预测的请求模式
+4. **监控**: 定期检查`/health`和`/stats`端点
+5. **日志**: 配置适当的日志级别和轮转策略
