+
+## 世界地图实现建议
+
+对于前端实现世界地图并显示区域坐标，推荐以下方案：
+
+### 1. 使用开源地图库
+
+- **Leaflet.js**: 轻量级开源地图库，易于集成
+- **Mapbox**: 提供丰富的地图样式和交互功能
+- **Google Maps API**: 功能强大但需要API密钥
+
+### 2. 实现步骤
+
+1. **获取区域数据**:
+   使用 `/api/area/all` 接口获取所有包含坐标信息的区域
+
+2. **初始化地图**:
+   ```javascript
+   // Leaflet示例
+   const map = L.map('map').setView([0, 0], 2);
+   L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
+     attribution: '© OpenStreetMap contributors'
+   }).addTo(map);
+   ```
+
+3. **添加区域标记**:
+   ```javascript
+   // 假设areas是从API获取的数据
+   areas.forEach(area => {
+     if (area.latitude && area.longitude) {
+       const marker = L.marker([area.latitude, area.longitude]).addTo(map);
+       marker.bindPopup(`<b>${area.name}</b>`);
+     }
+   });
+   ```
+
+4. **添加交互功能**:
+   - 点击标记显示区域详情
+   - 搜索和筛选功能
+   - 编辑坐标功能（调用更新API）
+
+### 3. 坐标输入建议
+
+在区域管理界面，可以添加以下功能来辅助坐标输入：
+
+1. 提供搜索框，根据地点名称自动获取坐标
+2. 集成小型地图，允许用户点击选择位置
+3. 添加验证，确保输入的坐标在有效范围内
+
+## 数据模型说明
+
+### Area 实体
+
+| 字段名 | 类型 | 描述 | 是否必填 |
+|--------|------|------|----------|
+| id | number | 区域ID | 否（自动生成） |
+| name | string | 区域名称 | 是 |
+| latitude | number | 纬度（范围：-90 到 90） | 否 |
+| longitude | number | 经度（范围：-180 到 180） | 否 |
+| createdAt | Date | 创建时间 | 否（自动生成） |
+| updatedAt | Date | 更新时间 | 否（自动生成） |
+
+## 错误处理
+
+API可能返回的错误信息：
+
+- `区域名称已存在`: 当尝试创建或更新区域名称与现有名称重复时
+- `区域不存在`: 当尝试更新或删除不存在的区域时
+- `权限错误`: 当请求缺少有效的授权令牌时

+# 数据库迁移指南
+
+为了支持区域坐标功能，需要执行数据库迁移操作，将新增的 `latitude` 和 `longitude` 字段添加到数据库表中。
+
+## 执行迁移步骤
+
+### 1. 生成迁移文件
+
+运行以下命令生成迁移文件：
+
+```bash
+npm run migration:generate -- ./src/db/migrations/AddCoordinatesToArea
+```
+
+### 2. 检查迁移文件
+
+生成的迁移文件会自动包含添加 `latitude` 和 `longitude` 字段的SQL语句。您可以检查文件内容确保迁移逻辑正确。
+
+### 3. 执行迁移
+
+运行以下命令执行迁移，将更改应用到数据库：
+
+```bash
+npm run migration:run
+```
+
+## 手动迁移SQL（可选）
+
+如果需要手动执行SQL，可以使用以下语句：
+
+```sql
+ALTER TABLE `area` 
+ADD COLUMN `latitude` DECIMAL(10,6) NULL AFTER `name`,
+ADD COLUMN `longitude` DECIMAL(10,6) NULL AFTER `latitude`;
+```
+
+## 回滚迁移（如需）
+
+如果遇到问题，可以使用以下命令回滚迁移：
+
+```bash
+npm run typeorm -- migration:revert -d src/db/datasource.ts
+```
+
+## 注意事项
+
+- 确保在执行迁移前备份数据库
+- 迁移不会影响现有数据，新增字段默认为 NULL
+- 迁移后，可以通过API开始为区域添加坐标信息
