Remote -> Many 多文件传输 Implementation Plan

For agentic workers: REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 为 Remote -> Many 传输模式添加支持选择多个远程文件的能力，所有文件推送到统一目标目录，使用并发传输提升效率。

Architecture: 在现有单文件传输架构上扩展，前端 SftpFilePickerModal.vue 支持多选模式（v-model 从 string 改为 string[]），TransfersView.vue 和 transfers.ts 支持批量源文件路径。后端 createTransferRemoteTask() 保持单文件任务接口，前端并发创建多个任务并复用现有 SSE 进度追踪机制。

Tech Stack:

Frontend: Vue 3 + TypeScript + Pinia
Backend: Spring Boot 2.7 + Java 8 + JSch
SSE (Server-Sent Events) 用于进度追踪
并发控制复用 runWithConcurrency 工具函数

文件结构

文件	职责
`frontend/src/components/SftpFilePickerModal.vue`	支持多选模式，v-model 改为 string[]，批量选择文件路径
`frontend/src/views/TransfersView.vue`	`remoteSourcePath: string` → `remoteSourcePaths: string[]`，支持文件选择按钮和批量路径输入
`frontend/src/stores/transfers.ts`	新增 `startRemoteToManyMulti()` 并发处理多个源文件，复用现有 `runWithConcurrency` 和 SSE 机制
`frontend/src/api/sftp.ts`	新增 `createRemoteToManyMultiTask()` 批量创建远程传输任务（可选，可直接复用 `createRemoteTransferTask`）
`backend/src/main/java/com/sshmanager/controller/SftpController.java`	新增 `createRemoteToManyMultiTask()` 支持 `sourcePaths: String[]`，每个文件创建独立任务
`backend/src/main/java/com/sshmanager/service/SftpService.java`	无改动（`transferRemote()` 已支持单文件，复用即可）

Task 1: 后端新增批量任务创建 API

Files:

Modify: backend/src/main/java/com/sshmanager/controller/SftpController.java:504-547
Step 1: 修改 SftpController.createTransferRemoteTask() 支持多源路径

@PostMapping("/transfer-remote/batch-tasks")
public ResponseEntity<Map<String, Object>> createRemoteToManyMultiTask(
        @RequestParam Long sourceConnectionId,
        @RequestParam String[] sourcePaths,
        @RequestParam Long targetConnectionId,
        @RequestParam String targetDirOrPath,
        Authentication authentication) {
    Long userId = getCurrentUserId(authentication);
    
    if (sourcePaths == null || sourcePaths.length == 0) {
        Map<String, Object> err = new HashMap<>();
        err.put("error", "sourcePaths is required");
        return ResponseEntity.badRequest().body(err);
    }
    
    if (sourceConnectionId == null) {
        Map<String, Object> err = new HashMap<>();
        err.put("error", "sourceConnectionId is required");
        return ResponseEntity.badRequest().body(err);
    }
    
    if (targetConnectionId == null) {
        Map<String, Object> err = new HashMap<>();
        err.put("error", "targetConnectionId is required");
        return ResponseEntity.badRequest().body(err);
    }
    
    if (targetDirOrPath == null || targetDirOrPath.trim().isEmpty()) {
        Map<String, Object> err = new HashMap<>();
        err.put("error", "targetDirOrPath is required");
        return ResponseEntity.badRequest().body(err);
    }
    
    List<Map<String, Object>> taskResponses = new ArrayList<>();
    
    for (String sourcePath : sourcePaths) {
        ResponseEntity<Map<String, String>> validation = validateTransferPaths(sourcePath, targetDirOrPath);
        if (validation != null) {
            Map<String, Object> err = new HashMap<>();
            err.putAll(validation.getBody());
            err.put("sourcePath", sourcePath);
            taskResponses.add(err);
            continue;
        }
        
        String sourcePathTrimmed = sourcePath.trim();
        String filename = sourcePathTrimmed.split("/").filter(p -> !p.isEmpty()).reduce((a, b) -> b).orElse(sourcePathTrimmed);
        String targetPath = targetDirOrPath.endsWith("/") ? (targetDirOrPath + filename) : targetDirOrPath;
        
        TransferTaskStatus status = new TransferTaskStatus(UUID.randomUUID().toString(), userId, sourceConnectionId, targetConnectionId,
            sourcePathTrimmed, targetPath);
        status.setController(this);
        String taskKey = transferTaskKey(userId, status.getTaskId());
        transferTasks.put(taskKey, status);
        
        Future<?> future = transferTaskExecutor.submit(() -> {
            status.setStatus("running");
            try {
                if (Thread.currentThread().isInterrupted()) {
                    status.markCancelled();
                    return;
                }
                executeTransfer(userId, sourceConnectionId, sourcePathTrimmed, targetConnectionId, targetPath, status);
                status.markSuccess();
            } catch (Exception e) {
                if (e instanceof InterruptedException || Thread.currentThread().isInterrupted()) {
                    status.markCancelled();
                    return;
                }
                status.markError(toSftpErrorMessage(e, sourcePathTrimmed, "transfer"));
                log.warn("SFTP transfer task failed: taskId={}, sourceConnectionId={}, sourcePath={}, targetConnectionId={}, targetPath={}, error={}",
                    status.getTaskId(), sourceConnectionId, sourcePathTrimmed, targetConnectionId, targetPath, e.getMessage(), e);
            }
        });
        status.setFuture(future);
        
        taskResponses.add(status.toResponse());
    }
    
    Map<String, Object> result = new HashMap<>();
    result.put("tasks", taskResponses);
    result.put("count", taskResponses.size());
    return ResponseEntity.ok(result);
}

Step 2: 修改 SftpController.createTransferRemoteTask() 保持单文件兼容性

@PostMapping("/transfer-remote/tasks")
public ResponseEntity<Map<String, Object>> createTransferRemoteTask(
        @RequestParam Long sourceConnectionId,
        @RequestParam String sourcePath,
        @RequestParam Long targetConnectionId,
        @RequestParam String targetPath,
        Authentication authentication) {
    Long userId = getCurrentUserId(authentication);
    ResponseEntity<Map<String, String>> validation = validateTransferPaths(sourcePath, targetPath);
    if (validation != null) {
        Map<String, Object> err = new HashMap<>();
        err.putAll(validation.getBody());
        return ResponseEntity.status(validation.getStatusCode()).body(err);
    }

    TransferTaskStatus status = new TransferTaskStatus(UUID.randomUUID().toString(), userId, sourceConnectionId, targetConnectionId,
        sourcePath.trim(), targetPath.trim());
    status.setController(this);
    String taskKey = transferTaskKey(userId, status.getTaskId());
    transferTasks.put(taskKey, status);

    Future<?> future = transferTaskExecutor.submit(() -> {
        status.setStatus("running");
        try {
            if (Thread.currentThread().isInterrupted()) {
                status.markCancelled();
                return;
            }
            executeTransfer(userId, sourceConnectionId, sourcePath, targetConnectionId, targetPath, status);
            status.markSuccess();
        } catch (Exception e) {
            if (e instanceof InterruptedException || Thread.currentThread().isInterrupted()) {
                status.markCancelled();
                return;
            }
            status.markError(toSftpErrorMessage(e, sourcePath, "transfer"));
            log.warn("SFTP transfer task failed: taskId={}, sourceConnectionId={}, sourcePath={}, targetConnectionId={}, targetPath={}, error={}",
                status.getTaskId(), sourceConnectionId, sourcePath, targetConnectionId, targetPath, e.getMessage(), e);
        }
    });
    status.setFuture(future);

    return ResponseEntity.ok(status.toResponse());
}

Step 3: 运行后端编译测试

cd /home/liumangmang/GiteaRepos/LiuMangMang/ssh-manager/backend && mvn clean compile

Expected: Compilation succeeds with no errors.

Step 4: 启动后端并验证 API

cd /home/liumangmang/GiteaRepos/LiuMangMang/ssh-manager/backend && mvn spring-boot:run

验证 /api/sftp/transfer-remote/tasks 接口（单文件）仍正常工作
验证 /api/sftp/transfer-remote/batch-tasks 接口存在，可通过 curl 验证：

curl -X POST "http://localhost:48080/api/sftp/transfer-remote/batch-tasks" \
  -H "Authorization: Bearer <token>" \
  -d "sourceConnectionId=1&sourcePaths=/path/file1.txt&sourcePaths=/path/file2.txt&targetConnectionId=2&targetDirOrPath=/target/"

Expected: Response includes tasks array with individual task status.

Task 2: 前端 API 封装和 Store 改造

Files:

Modify: frontend/src/api/sftp.ts:226-230
Modify: frontend/src/stores/transfers.ts:368-410
Step 1: 添加 createRemoteToManyMultiTask API

export function createRemoteToManyMultiTask(
  sourceConnectionId: number,
  sourcePaths: string[],
  targetConnectionId: number,
  targetDirOrPath: string
) {
  const params = new URLSearchParams()
  params.append('sourceConnectionId', String(sourceConnectionId))
  sourcePaths.forEach((p) => params.append('sourcePaths', p))
  params.append('targetConnectionId', String(targetConnectionId))
  params.append('targetDirOrPath', targetDirOrPath)
  
  return client.post<{ tasks: RemoteTransferTask[]; count: number }>('/sftp/transfer-remote/batch-tasks', null, {
    params,
  })
}

Step 2: 新增 startRemoteToManyMulti store method

async function startRemoteToManyMulti(params: {
  sourceConnectionId: number
  sourcePaths: string[]
  targetConnectionIds: number[]
  targetDirOrPath: string
  concurrency?: number
}) {
  const { sourceConnectionId, sourcePaths, targetConnectionIds, targetDirOrPath } = params
  const concurrency = params.concurrency ?? 3

  if (sourceConnectionId == null) return

  const runId = uid('run')
  const runItems: TransferItem[] = []
  
  for (const sourcePath of sourcePaths) {
    const filename = sourcePath.split('/').filter(Boolean).pop() || sourcePath
    for (const targetId of targetConnectionIds) {
      runItems.push({
        id: uid('item'),
        label: `#${sourceConnectionId}:${sourcePath} -> #${targetId}:${targetDirOrPath}`,
        status: 'queued' as const,
        progress: 0,
      })
    }
  }

  const run: TransferRun = {
    id: runId,
    mode: 'REMOTE_TO_MANY' as const,
    title: `Remote ${sourcePaths.length} files -> ${targetConnectionIds.length} targets`,
    createdAt: now(),
    items: runItems,
    status: 'queued' as const,
  }

  runs.value = [run, ...runs.value]

  let cancelled = false
  const unsubscribers: (() => void)[] = []
  controllers.set(runId, {
    abortAll: () => {
      cancelled = true
    },
    unsubscribers,
  })

  const tasks: (() => Promise<void>)[] = sourcePaths.flatMap((sourcePath) => {
    const filename = sourcePath.split('/').filter(Boolean).pop() || sourcePath
    return targetConnectionIds.map((targetId, index) => {
      const itemIndex = runItems.findIndex((i) => 
        i.label.includes(filename) && i.label.includes(`#${targetId}`)
      )
      if (itemIndex === -1) return null
      const item = runItems[itemIndex]!
      
      return async () => {
        if (item.status === 'cancelled' || cancelled) return
        item.status = 'running'
        item.progress = 0
        item.startedAt = now()
        runs.value = [...runs.value]
        console.log('[Remote->Many Multi] Starting transfer:', item.label, 'targetId:', targetId)
        try {
          const targetPath = targetDirOrPath.endsWith('/') 
            ? targetDirOrPath + filename 
            : targetDirOrPath

          const task = await createRemoteToManyMultiTask(sourceConnectionId, [sourcePath], targetId, targetPath)
          const taskId = task.data.tasks[0]?.taskId
          if (!taskId) {
            throw new Error('Failed to create transfer task')
          }
          console.log('[Remote->Many Multi] Task created:', taskId)
          await waitForRemoteTransfer(taskId, (progress) => {
            console.log('[Remote->Many Multi] Progress update:', progress, 'item:', item.label)
            item.progress = Math.max(item.progress || 0, progress)
            runs.value = [...runs.value]
          }, unsubscribers)

          item.status = 'success'
          item.progress = 100
          item.finishedAt = now()
          console.log('[Remote->Many Multi] Transfer completed:', item.label)
          runs.value = [...runs.value]
        } catch (e: unknown) {
          const err = e as { response?: { data?: { error?: string } } }
          const msg = err?.response?.data?.error || (e as Error)?.message || 'Transfer failed'
          console.error('[Remote->Many Multi] Transfer failed:', item.label, 'error:', msg)
          if (msg === 'Cancelled') {
            item.status = 'cancelled'
            item.progress = 100
          } else {
            item.status = 'error'
            item.progress = 100
            item.message = msg
          }
          item.finishedAt = now()
          runs.value = [...runs.value]
        } finally {
          runs.value = [...runs.value]
        }
      }
    }).filter((t): t is () => Promise<void> => t !== null)
  })

  await runWithConcurrency(tasks, concurrency)
  runs.value = [...runs.value]
}

Step 3: 在 transfers.ts export 中添加新方法

return {
  runs,
  recentRuns,
  controllers,
  clearRuns,
  cancelRun,
  startLocalToMany,
  startRemoteToMany,
  startRemoteToManyMulti,
}

Step 4: 运行前端类型检查

cd /home/liumangmang/GiteaRepos/LiuMangMang/ssh-manager/frontend && npm run build

Expected: Build succeeds with no TypeScript errors.

Task 3: 端到端测试和验证

Files:

Manual verification only
Step 1: 清空数据库并重启后端

cd /home/liumangmang/GiteaRepos/LiuMangMang/ssh-manager/backend
rm -rf data/sshmanager
mvn spring-boot:run

Step 2: 启动前端

cd /home/liumangmang/GiteaRepos/LiuMangMang/ssh-manager/frontend
npm run dev

Step 3: 创建测试连接
在 Connections 页面添加 2-3 个测试连接（例如本地 Docker 容器）
Step 4: Remote -> Many 单文件传输（兼容性测试）
切换到 Remote -> Many 标签页
选择源连接
使用文件选择器选择单个文件（或手动输入路径）
选择一个目标连接
点击 "开始转发"
验证任务创建成功，进度栏正常更新
Step 5: Remote -> Many 多文件传输（新增功能）
切换到 Remote -> Many 标签页
点击 "浏览" 按钮
在文件选择器中：
- 单击多个文件切换选中状态
- 右上角 "确认 (N)" 按钮应显示选中数量
- 选中 2-3 个文件后点击确认
源路径输入框应显示类似 /path/file1.txt, /path/file2.txt
选择一个目标连接
点击 "开始转发"
验证任务队列中创建了 sourceFiles.length * targetConnections.length 个子任务
每个子任务的进度独立更新
全部完成后状态应为 "Success"
Step 6: 并发控制验证
设置并发为 1（串行）
选择 3 个源文件和 2 个目标连接（共 6 个子任务）
观察任务执行顺序，应为串行执行
设置并发为 3，重复以上步骤，观察并发执行
Step 7: 错误处理验证
选择不存在的文件路径
验证错误消息正确显示在对应子任务中
其他子任务不受影响继续执行
Step 8: 取消任务验证
开始传输后立即点击 "取消任务"
验证所有未完成任务标记为 "Cancelled"
控制台日志显示取消信息
Step 9: 登录流程验证
退出登录
重新登录
创建新的传输任务
验证认证流程正常

Task 4: 文档和清理

Files:

Create: docs/REMOTE_MULTI_FILE_TRANSFER.md
Step 1: 创建功能文档

# Remote -> Many 多文件传输功能说明

## 功能概述
Remote -> Many 模式现在支持选择多个远程文件，所有文件推送到统一目标目录，使用并发传输提升效率。

## 使用方式

### 前端操作
1. 切换到 Remote -> Many 标签页
2. 选择源连接
3. 点击 "浏览" 按钮打开文件选择器
4. 在文件选择器中：
   - 单击文件切换选中状态
   - 选择多个文件后点击右上角 "确认 (N)" 按钮
   - 或手动在源路径输入框输入路径（英文逗号分隔）
5. 选择一个或多个目标连接
6. 设置并发数（默认 3）
7. 点击 "开始转发"

### 并发控制
- 并发数支持 1-6，建议 2-4
- 并发越高越吃带宽与 CPU
- 后端是逐个调用 transfer-remote；并发适中即可

### 进度追踪
- 每个文件-目标对独立显示进度
- 悬停可查看详细错误信息
- 支持取消所有未完成任务

## 技术细节

### API 端点
- `POST /api/sftp/transfer-remote/batch-tasks` - 批量创建传输任务
  - `sourceConnectionId` - 源连接 ID
  - `sourcePaths` - 源文件路径数组（可重复）
  - `targetConnectionId` - 目标连接 ID
  - `targetDirOrPath` - 目标目录或路径
  
- `GET /api/sftp/transfer-remote/tasks/{taskId}/progress` - SSE 进度追踪

### 并发控制
- 前端使用 `runWithConcurrency` 工具函数
- 每个文件-目标对创建独立任务
- 任务状态独立追踪，互不影响

### 错误处理
- 单个文件传输失败不影响其他文件
- 错误信息显示在对应子任务中
- 支持取消未完成任务

Step 2: 运行最终构建验证

cd /home/liumangmang/GiteaRepos/LiuMangMang/ssh-manager && docker compose -f docker/docker-compose.yml up --build -d

Expected: Docker service starts successfully with no errors.

Step 3: 查看日志

docker compose -f docker/docker-compose.yml logs -f

Verify: No stack traces or critical errors in application logs.

Step 4: 提交代码

cd /home/liumangmang/GiteaRepos/LiuMangMang/ssh-manager
git add -A
git commit -m "feat: add multi-file support for Remote -> Many transfer mode"
