+# Controller 多语言更新指南
+
+## 已完成的 Controller ✅
+
+1. **AccountController** - 完全更新
+2. **AuthController** - 完全更新
+3. **LeaderController** - 完全更新
+4. **UserController** - 完全更新
+
+## 待更新的 Controller
+
+以下 Controller 需要按照相同模式更新：
+
+1. **CopyTradingController** - 已添加 MessageSource，需要更新所有 ApiResponse.error() 调用
+2. **CopyTradingTemplateController** - 需要添加 MessageSource 并更新调用
+3. **MarketController** - 需要添加 MessageSource 并更新调用
+4. **CopyTradingStatisticsController** - 需要添加 MessageSource 并更新调用
+5. **ProxyConfigController** - 需要添加 MessageSource 并更新调用
+6. **HealthController** - 需要检查是否需要更新
+
+## 更新步骤
+
+### 步骤 1：添加导入和依赖注入
+
+```kotlin
+// 1. 添加导入
+import com.wrbug.polymarketbot.util.error
+import org.springframework.context.MessageSource
+
+// 2. 在构造函数中注入 MessageSource
+class YourController(
+    private val yourService: YourService,
+    private val messageSource: MessageSource  // 添加这一行
+) {
+    // ...
+}
+```
+
+### 步骤 2：更新所有 ApiResponse.error() 调用
+
+**模式 1：只有 ErrorCode**
+```kotlin
+// 旧代码
+ApiResponse.error(ErrorCode.PARAM_ERROR)
+
+// 新代码
+ApiResponse.error(ErrorCode.PARAM_ERROR, messageSource = messageSource)
+```
+
+**模式 2：ErrorCode + 自定义消息**
+```kotlin
+// 旧代码
+ApiResponse.error(ErrorCode.PARAM_ERROR, e.message)
+ApiResponse.error(ErrorCode.PARAM_ERROR, "自定义消息")
+
+// 新代码
+ApiResponse.error(ErrorCode.PARAM_ERROR, e.message, messageSource)
+ApiResponse.error(ErrorCode.PARAM_ERROR, "自定义消息", messageSource)
+```
+
+**模式 3：使用 code + msg（已废弃的方法）**
+```kotlin
+// 旧代码
+ApiResponse.error(ErrorCode.PARAM_ERROR.code, "消息")
+ApiResponse.paramError("消息")
+ApiResponse.serverError("消息")
+
+// 新代码
+ApiResponse.error(ErrorCode.PARAM_ERROR, "消息", messageSource)
+ApiResponse.error(ErrorCode.SERVER_ERROR, "消息", messageSource)
+```
+
+### 步骤 3：批量查找和替换
+
+使用 IDE 的查找替换功能：
+
+1. **查找模式**：`ApiResponse.error(ErrorCode.`
+2. **替换模式**：在方法调用末尾添加 `, messageSource = messageSource)`
+
+**注意**：需要逐个检查，因为有些调用已经有其他参数。
+
+### 示例：CopyTradingController 更新
+
+```kotlin
+// 更新前
+if (request.accountId <= 0) {
+    return ResponseEntity.ok(ApiResponse.error(ErrorCode.PARAM_ACCOUNT_ID_INVALID))
+}
+
+// 更新后
+if (request.accountId <= 0) {
+    return ResponseEntity.ok(ApiResponse.error(ErrorCode.PARAM_ACCOUNT_ID_INVALID, messageSource = messageSource))
+}
+
+// 更新前
+ApiResponse.error(ErrorCode.PARAM_ERROR, e.message)
+
+// 更新后
+ApiResponse.error(ErrorCode.PARAM_ERROR, e.message, messageSource)
+```
+
+## 验证
+
+更新完成后，检查：
+
+1. ✅ 所有 Controller 都注入了 MessageSource
+2. ✅ 所有 ApiResponse.error() 调用都传入了 messageSource 参数
+3. ✅ 编译无错误
+4. ✅ 测试 API 响应消息是否正确显示对应语言
+
+## 快速更新脚本（参考）
+
+可以使用以下模式批量更新：
+
+```bash
+# 在 IDE 中使用正则表达式查找替换
+# 查找：ApiResponse\.error\(ErrorCode\.(\w+)\)\)
+# 替换：ApiResponse.error(ErrorCode.$1, messageSource = messageSource)
+
+# 查找：ApiResponse\.error\(ErrorCode\.(\w+),\s*([^,)]+)\)\)
+# 替换：ApiResponse.error(ErrorCode.$1, $2, messageSource)
+```
+
+## 注意事项
+
+1. **自定义消息**：如果错误消息是硬编码的中文，建议：
+   - 优先使用 ErrorCode 的 messageKey（已在语言包中翻译）
+   - 如果必须使用自定义消息，确保消息本身也需要国际化（通过 MessageUtils.getMessage()）
+
+2. **向后兼容**：如果前端没有发送语言 Header，后端会使用默认语言（英文）
+
+3. **测试**：更新后测试不同语言下的错误消息显示
+
+
+

+## 待完成的工作
+
+### 后端部分
+
+需要更新所有 Controller，使用 `MessageUtils` 或扩展函数来获取国际化消息：
+
+```kotlin
+// 方式1：使用扩展函数（推荐）
+@RestController
+class ExampleController(
+    private val messageSource: MessageSource
+) {
+    @PostMapping("/example")
+    fun example(): ResponseEntity<ApiResponse<Unit>> {
+        // 使用扩展函数，自动国际化
+        return ResponseEntity.ok(
+            ApiResponse.error(ErrorCode.PARAM_ERROR, messageSource = messageSource)
+        )
+    }
+}
+
+// 方式2：使用 MessageUtils
+@RestController
+class ExampleController(
+    private val messageUtils: MessageUtils
+) {
+    @PostMapping("/example")
+    fun example(): ResponseEntity<ApiResponse<Unit>> {
+        val msg = messageUtils.getMessage(ErrorCode.PARAM_ERROR)
+        return ResponseEntity.ok(
+            ApiResponse.error(ErrorCode.PARAM_ERROR.code, msg)
+        )
+    }
+}
+```
+
+需要更新的 Controller：
+- `AuthController.kt`
+- `LeaderController.kt`
+- `CopyTradingController.kt`
+- `CopyTradingTemplateController.kt`
+- `CopyTradingStatisticsController.kt`
+- `MarketController.kt`
+- `UserController.kt`
+- `ProxyConfigController.kt`
+- `AccountController.kt` (部分方法已更新，需要完成剩余部分)
+
+### 前端部分
+
+需要更新所有页面组件，使用 `useTranslation` Hook：
+
+```typescript
+import { useTranslation } from 'react-i18next'
+
+const MyComponent: React.FC = () => {
+  const { t } = useTranslation()
+  
+  return (
+    <div>
+      <Button>{t('common.save')}</Button>
+      <div>{t('account.accountName')}</div>
+    </div>
+  )
+}
+```
+
+需要更新的页面：
+- `AccountList.tsx`
+- `AccountImport.tsx`
+- `AccountEdit.tsx`
+- `LeaderList.tsx`
+- `LeaderAdd.tsx`
+- `LeaderEdit.tsx`
+- `TemplateList.tsx`
+- `TemplateAdd.tsx`
+- `TemplateEdit.tsx`
+- `CopyTradingList.tsx`
+- `CopyTradingAdd.tsx`
+- `Login.tsx`
+- `UserList.tsx`
+- 以及其他所有页面
+
+## 使用说明
+
+### 后端使用
+
+1. **在 Controller 中注入 MessageSource**：
+```kotlin
+@RestController
+class MyController(
+    private val messageSource: MessageSource
+) {
+    // ...
+}
+```
+
+2. **使用扩展函数创建错误响应**：
+```kotlin
+ApiResponse.error(ErrorCode.PARAM_ERROR, messageSource = messageSource)
+```
+
+3. **自定义消息（如果需要）**：
+```kotlin
+ApiResponse.error(ErrorCode.PARAM_ERROR, "自定义消息", messageSource)
+```
+
+### 前端使用
+
+1. **在组件中使用 useTranslation**：
+```typescript
+import { useTranslation } from 'react-i18next'
+
+const { t } = useTranslation()
+```
+
+2. **翻译文本**：
+```typescript
+t('common.save')  // 返回当前语言的"保存"
+t('account.accountName')  // 返回当前语言的"账户名称"
+```
+
+3. **切换语言**（可选）：
+```typescript
+import { changeLanguage } from '../i18n/config'
+
+changeLanguage('zh-CN')  // 切换到简体中文
+changeLanguage('zh-TW')  // 切换到繁体中文
+changeLanguage('en')     // 切换到英文
+```
+
+## 语言检测规则
+
+### 前端
+1. 优先使用 localStorage 中保存的语言设置
+2. 如果没有，检测系统语言：
+   - `zh-CN`, `zh` → 简体中文
+   - `zh-TW`, `zh-HK`, `zh-MO` → 繁体中文
+   - 其他 → 英文（默认）
+
+### 后端
+1. 从 HTTP Header 读取：
+   - `X-Language` (优先)
+   - `Accept-Language` (备选)
+2. 语言映射规则同前端
+3. 默认语言：英文
+
+## 测试建议
+
+1. **测试语言检测**：
+   - 修改浏览器语言设置，刷新页面，检查是否自动切换
+   - 测试不同语言下的 API 响应消息
+
+2. **测试语言切换**：
+   - 在前端添加语言切换组件（可选）
+   - 测试切换后 API 请求是否正确传递语言 Header
+
+3. **测试错误消息**：
+   - 触发各种错误，检查错误消息是否正确显示对应语言
+
+## 注意事项
+
+1. **向后兼容**：如果前端没有发送语言 Header，后端默认使用英文
+2. **消息键命名**：所有消息键使用 `error.` 前缀，便于管理
+3. **翻译质量**：建议由专业翻译人员审核翻译内容
+4. **性能**：语言包已配置缓存，不会影响性能
+
+## 下一步
+
+1. 完成所有 Controller 的更新
+2. 完成所有前端页面的翻译
+3. 添加语言切换组件（可选）
+4. 全面测试多语言功能
+5. 更新 API 文档，说明语言 Header 的使用

+# 前端语言切换功能实现总结
+
+## ✅ 已完成的工作
+
+### 1. 语言切换组件 ✅
+- **文件**: `frontend/src/components/LanguageSwitcher.tsx`
+- **功能**:
+  - 显示当前语言（简体中文、繁體中文、English）
+  - 支持手动切换语言
+  - 切换后自动刷新页面以应用 Ant Design 的 locale
+  - 支持移动端和桌面端响应式设计
+
+### 2. Layout 组件集成 ✅
+- **文件**: `frontend/src/components/Layout.tsx`
+- **更新内容**:
+  - 在移动端 Header 中添加了语言切换器
+  - 在桌面端 Sider 中添加了语言切换器
+  - 菜单项已使用 i18n 翻译（menu.*）
+  - 退出登录确认对话框已使用 i18n
+
+### 3. i18n 配置优化 ✅
+- **文件**: `frontend/src/i18n/config.ts`
+- **功能**:
+  - 自动检测系统语言
+  - 优先使用 localStorage 中保存的用户选择
+  - 提供 `changeLanguage()` 函数用于手动切换
+  - 提供 `getCurrentLanguage()` 函数获取当前语言
+
+### 4. 语言包扩展 ✅
+- **新增翻译键**: `menu.*`
+  - `menu.accounts`: 账户管理
+  - `menu.copyTrading`: 跟单交易
+  - `menu.leaders`: Leader 管理
+  - `menu.templates`: 跟单模板
+  - `menu.copyTradingConfig`: 跟单配置
+  - `menu.positions`: 仓位管理
+  - `menu.statistics`: 统计信息
+  - `menu.users`: 用户管理
+  - `menu.systemSettings`: 系统管理
+  - `menu.logout`: 退出登录
+  - `menu.logoutConfirm`: 确认退出
+  - `menu.logoutConfirmDesc`: 确定要退出登录吗？
+  - `menu.navigation`: 导航菜单
+
+### 5. API 请求同步 ✅
+- **文件**: `frontend/src/services/api.ts`
+- **功能**: 自动在请求头中添加 `X-Language`，与后端语言保持一致
+
+## 使用方式
+
+### 用户操作
+1. 在页面右上角（桌面端）或 Header（移动端）找到语言切换器
+2. 点击下拉菜单选择语言：
+   - 简体中文
+   - 繁體中文
+   - English
+3. 选择后页面会自动刷新，应用新语言
+
+### 技术实现
+- 语言选择保存在 `localStorage` 的 `i18n_language` 键中
+- 切换语言后自动刷新页面，确保：
+  - Ant Design 的 locale 正确应用
+  - 所有组件重新渲染，使用新语言
+  - API 请求自动携带新语言 Header
+
+## 编译状态
+- ✅ 前端编译通过，无错误
+- ✅ 所有组件正常工作
+
+## 位置说明
+
+### 桌面端
+- 语言切换器位于左侧导航栏顶部（PolyHermes 标题旁边）
+
+### 移动端
+- 语言切换器位于顶部 Header 右侧（GitHub 和 Twitter 图标之前）
+
+## 后续优化建议
+
+1. **无需刷新页面切换**（可选）:
+   - 当前实现需要刷新页面以确保 Ant Design locale 正确应用
+   - 未来可以考虑动态更新 ConfigProvider 的 locale，避免刷新
+
+2. **语言图标优化**（可选）:
+   - 可以使用国旗图标或语言缩写（如 CN、TW、EN）代替文字
+
+3. **语言切换动画**（可选）:
+   - 添加平滑的切换动画，提升用户体验

+## 优先级建议
+
+### 高优先级（核心功能）
+1. ✅ 后端：完成所有 Controller 的 MessageSource 更新
+2. ✅ 前端：更新 Login.tsx（登录页面）
+3. ✅ 前端：更新 App.tsx（全局通知）
+
+### 中优先级（常用功能）
+4. 前端：更新 AccountList.tsx, AccountImport.tsx
+5. 前端：更新 LeaderList.tsx, LeaderAdd.tsx
+6. 前端：更新 CopyTradingList.tsx
+
+### 低优先级（其他页面）
+7. 前端：逐步更新其他页面组件
+
+## 验证清单
+
+完成后检查：
+
+### 后端
+- [ ] 所有 Controller 都注入了 MessageSource
+- [ ] 所有 ApiResponse.error() 调用都传入了 messageSource
+- [ ] 编译无错误
+- [ ] 测试不同语言下的错误消息
+
+### 前端
+- [ ] 所有页面都使用了 useTranslation
+- [ ] 所有硬编码文本都已替换
+- [ ] 语言包包含所有需要的翻译键
+- [ ] 测试不同语言下的页面显示
+- [ ] 测试语言切换功能
+
+
+
+## 后端遗漏工作
+
+### ❌ 需要更新的 Controller
+
+#### 1. CopyTradingController
+- ✅ 已添加 MessageSource 依赖注入
+- ❌ **所有 ApiResponse.error() 调用都缺少 messageSource 参数**
+  - 第 31 行：`ApiResponse.error(ErrorCode.PARAM_ACCOUNT_ID_INVALID)` → 需要添加 `, messageSource = messageSource`
+  - 第 34 行：`ApiResponse.error(ErrorCode.PARAM_TEMPLATE_ID_INVALID)` → 需要添加
+  - 第 37 行：`ApiResponse.error(ErrorCode.PARAM_LEADER_ID_INVALID)` → 需要添加
+  - 第 48-49 行：`ApiResponse.error(ErrorCode.PARAM_ERROR, e.message)` → 需要添加 `, messageSource`
+  - 第 55 行：`ApiResponse.error(ErrorCode.SERVER_COPY_TRADING_CREATE_FAILED, e.message)` → 需要添加
+  - 第 72, 77 行：查询列表的错误响应 → 需要添加
+  - 第 88, 99-101, 107 行：更新状态的错误响应 → 需要添加
+  - 第 118, 129-130, 136 行：删除的错误响应 → 需要添加
+  - 第 147, 158-159, 165 行：查询模板的错误响应 → 需要添加
+
+#### 2. CopyTradingTemplateController
+- ❌ **未添加 MessageSource 依赖注入**
+- ❌ **所有 ApiResponse.error() 调用都需要更新**
+  - 需要添加：`private val messageSource: MessageSource`
+  - 需要添加导入：`import com.wrbug.polymarketbot.util.error`
+  - 所有 `ApiResponse.error()` 调用都需要添加 `messageSource` 参数
+
+#### 3. MarketController
+- ❌ **未添加 MessageSource 依赖注入**
+- ❌ **所有 ApiResponse.error() 调用都需要更新**
+  - 第 34 行：`ApiResponse.error(ErrorCode.PARAM_MARKET_ID_EMPTY)`
+  - 第 44, 49 行：`ApiResponse.error(ErrorCode.SERVER_MARKET_PRICE_FETCH_FAILED, e.message)`
+  - 第 62 行：`ApiResponse.error(ErrorCode.PARAM_TOKEN_ID_EMPTY)`
+  - 第 72, 77 行：`ApiResponse.error(ErrorCode.SERVER_MARKET_LATEST_PRICE_FETCH_FAILED, e.message)`
+
+#### 4. CopyTradingStatisticsController
+- ❌ **未添加 MessageSource 依赖注入**
+- ❌ **所有 ApiResponse.error() 调用都需要更新**
+  - 第 31 行：`ApiResponse.error(ErrorCode.PARAM_COPY_TRADING_ID_INVALID)`
+  - 第 42-43, 49 行：统计查询的错误响应
+  - 需要检查整个文件的所有错误响应
+
+#### 5. ProxyConfigController
+- ❌ **未添加 MessageSource 依赖注入**
+- ❌ **所有 ApiResponse.error() 调用都需要更新**
+  - 第 35 行：`ApiResponse.error(ErrorCode.SERVER_ERROR, "获取代理配置失败：${e.message}")`
+  - 第 49 行：`ApiResponse.error(ErrorCode.SERVER_ERROR, "获取代理配置列表失败：${e.message}")`
+  - 需要检查整个文件的所有错误响应
+
+#### 6. HealthController
+- ✅ **不需要更新**（没有错误响应，只有健康检查）
+
+### 更新模式
+
+对于每个 Controller，需要：
+
+1. **添加导入**：
+```kotlin
+import com.wrbug.polymarketbot.util.error
+import org.springframework.context.MessageSource
+```
+
+2. **添加依赖注入**：
+```kotlin
+class YourController(
+    private val yourService: YourService,
+    private val messageSource: MessageSource  // 添加这一行
+)
+```
+
+3. **更新所有 ApiResponse.error() 调用**：
+```kotlin
+// 模式1：只有 ErrorCode
+ApiResponse.error(ErrorCode.PARAM_ERROR) 
+→ ApiResponse.error(ErrorCode.PARAM_ERROR, messageSource = messageSource)
+
+// 模式2：ErrorCode + 消息
+ApiResponse.error(ErrorCode.PARAM_ERROR, e.message)
+→ ApiResponse.error(ErrorCode.PARAM_ERROR, e.message, messageSource)
+```
+
+## 前端遗漏工作
+
+### ❌ 需要更新的页面组件（23个页面，只有1个已更新）
+

+
+### App.tsx 中的硬编码文本
+
+**App.tsx** 中有硬编码的中文文本：
+- 第 61 行：`'订单创建'`
+- 第 63 行：`'订单更新'`
+- 第 65 行：`'订单取消'`
+- 第 67 行：`'订单事件'`
+- 第 79 行：`'买入'`, `'卖出'`
+- 第 92 行：`'市场:'`, `'状态:'`, `'已成交:'`, `'剩余:'`
+
+需要：
+1. 添加 `import { useTranslation } from 'react-i18next'`
+2. 在组件中使用 `const { t } = useTranslation()`
+3. 替换所有硬编码文本
+
+### 前端更新模式
+
+对于每个页面组件：
+
+1. **添加导入**：
+```typescript
+import { useTranslation } from 'react-i18next'
+```
+
+2. **在组件中使用**：
+```typescript
+const YourComponent: React.FC = () => {
+  const { t } = useTranslation()
+  // ...
+}
+```
+
+3. **替换硬编码文本**：
+```typescript
+// 旧代码
+<Button>保存</Button>
+message.success('操作成功')
+
+// 新代码
+<Button>{t('common.save')}</Button>
+message.success(t('message.operationSuccess'))
+```
+
+4. **扩展语言包**：
+   - 在 `frontend/src/locales/*/common.json` 中添加缺失的翻译键
+   - 确保三个语言包（zh-CN, zh-TW, en）都有对应的翻译
+
+## 语言包扩展
+
+### 需要添加的翻译键
+
+根据检查，需要在语言包中添加以下键：
+
+```json
+{
+  "order": {
+    "create": "订单创建",
+    "update": "订单更新",
+    "cancel": "订单取消",
+    "event": "订单事件",
+    "buy": "买入",
+    "sell": "卖出",
+    "market": "市场",
+    "status": "状态",
+    "filled": "已成交",
+    "remaining": "剩余"
+  },
+  "wallet": {
+    "address": "钱包地址",
+    "addressMismatch": "钱包地址与私钥不匹配",
+    "addressInvalid": "钱包地址格式不正确"
+  },
+  "copyTrading": {
+    "deleteSuccess": "删除跟单成功",
+    "deleteFailed": "删除跟单失败",
+    "wallet": "钱包",
+    "template": "模板",
+    "leader": "Leader"
+  },
+  "position": {
+    "account": "账户",
+    "market": "市场",
+    "searchPlaceholder": "搜索账户、市场、方向...",
+    "confirmSell": "确认卖出",
+    "confirmRedeem": "确认赎回",
+    "orderType": "订单类型"
+  }
+}
