## 开发指南
### 常见问题解决
#### 1. React严格模式导致的重复调用
在开发模式下，React严格模式会导致组件渲染两次，这可能导致：
- useEffect被重复执行
- 异步操作被重复调用
- 用户提示消息重复显示
**解决方案：**
- **全局消息去重配置**：在`frontend/src/utils/messageConfig.ts`中配置Antd message的全局设置
- **防重复机制**：使用缓存机制防止2秒内相同消息重复显示
- **最大显示数量限制**：设置`maxCount: 1`确保同时只显示一个消息
**全局配置：**
```typescript
// frontend/src/utils/messageConfig.ts
import { message } from 'antd';
// 配置全局消息设置，防止重复显示
message.config({
maxCount: 1, // 最多同时显示1个消息
duration: 3, // 消息显示3秒
top: 24, // 距离顶部24px
});
// 防重复消息函数
const messageCache = new Map<string, number>();
const DEBOUNCE_TIME = 2000; // 2秒内相同消息不重复显示
export const showMessage = (type: 'success' | 'error' | 'warning' | 'info', content: string) => {
const messageId = `${type}:${content}`;
const now = Date.now();
// 检查是否在防抖时间内
const lastTime = messageCache.get(messageId);
if (lastTime && now - lastTime < DEBOUNCE_TIME) {
return; // 跳过重复消息
}
// 更新缓存并显示消息
messageCache.set(messageId, now);
message[type](content);
};
```
**使用方法：**
- 在`main.tsx`中导入配置：`import './utils/messageConfig'`
- 在组件中正常使用`message.success()`、`message.error()`等
- 全局配置会自动防止重复消息显示

- 使用TypeScript确保类型安全
- 遵循Ant Design设计规范
### 数据库操作
1. **添加新的数据表**
- 在`internal/model/database.go`的`initTables()`方法中添加表结构
- 在`Database`结构体中添加相应的CRUD方法
- 在`DatabaseService`中添加业务逻辑方法
- 在`App`中添加API接口方法
2. **数据迁移**
- 数据库结构变更时，在`initTables()`方法中处理版本升级
- 使用事务确保数据一致性
3. **性能优化**
- 为常用查询字段添加索引
- 使用批量操作减少数据库交互
- 合理使用连接池和事务

## 配置说明
## 数据存储
### 数据库存储
应用使用SQLite数据库进行本地数据持久化，数据库文件位置：`~/.equipment-analyzer/equipment_analyzer.db`
#### 数据库表结构
- **equipment** - 装备基本信息表
- **equipment_operations** - 装备操作属性表
- **capture_sessions** - 抓包会话记录表
- **raw_packet_data** - 原始数据包表
- **app_settings** - 应用设置表
#### 数据库功能
- ✅ 装备数据的增删改查
- ✅ 批量数据导入导出
- ✅ 装备数据搜索和筛选
- ✅ 数据统计分析
- ✅ 应用设置持久化
- ✅ 抓包会话历史记录
### 配置文件
应用会在用户目录下创建配置文件：`~/.equipment-analyzer/config.json`
