+
+## 需求概述
+
+### 当前问题
+采购交易管理的导入功能采用同步处理方式,上传文件后需要等待导入完成,使用弹窗显示结果,阻塞用户操作。
+
+### 优化目标
+1. ✅ 采用后台异步处理,上传后立即关闭对话框
+2. ✅ 使用右上角通知提示,不使用弹窗
+3. ✅ 自动轮询导入状态,完成后通知用户
+4. ✅ 支持查看导入失败记录
+5. ✅ 状态持久化,刷新页面后仍可查看上次导入结果
+
+### 设计原则
+- **完全复用**员工信息维护的导入逻辑
+- 保持一致的交互体验
+- 最小化代码修改,复用已有组件
+
+---
+
+## 整体架构
+
+### 用户交互流程
+
+```
+用户点击"导入"按钮
+    ↓
+打开导入对话框
+    ↓
+选择Excel文件,点击"确定"
+    ↓
+上传文件到后端
+    ↓
+立即关闭导入对话框
+    ↓
+右上角显示通知:"导入任务已提交,正在后台处理中,处理完成后将通知您"
+    ↓
+系统后台每2秒轮询一次导入状态
+    ↓
+导入完成后,右上角显示结果通知:
+  - 全部成功: "导入完成!全部成功!共导入N条数据"
+  - 部分失败: "导入完成!成功N条,失败M条"
+    ↓
+如果有失败记录:
+  - 在页面操作栏显示"查看导入失败记录"按钮
+  - 带tooltip显示上次导入信息
+```
+
+### 数据存储策略
+
+使用localStorage存储导入任务状态,实现状态持久化:
+
+**存储Key**: `purchase_transaction_import_last_task`
+
+**存储内容**:
+```javascript
+{
+  taskId: "task-20250206-123456789",
+  status: "SUCCESS", // PROCESSING/SUCCESS/FAILED
+  saveTime: 1707225600000,
+  hasFailures: true,
+  totalCount: 1000,
+  successCount: 980,
+  failureCount: 20
+}
+```
+
+**数据保留时间**: 7天(过期自动清除)
+
+### 轮询机制
+
+- **轮询间隔**: 2秒
+- **最大轮询次数**: 150次(5分钟)
+- **超时处理**: 显示"导入任务处理超时,请联系管理员"
+- **状态检查**: 当status !== 'PROCESSING'时停止轮询
+
+---
+
+## 前端组件结构
+
+### 新增data属性
+
+```javascript
+data() {
+  return {
+    // ... 现有属性
+
+    // 导入轮询定时器
+    importPollingTimer: null,
+
+    // 是否显示查看失败记录按钮
+    showFailureButton: false,
+
+    // 当前导入任务ID
+    currentTaskId: null,
+
+    // 失败记录对话框
+    failureDialogVisible: false,
+    failureList: [],
+    failureLoading: false,
+    failureTotal: 0,
+    failureQueryParams: {
+      pageNum: 1,
+      pageSize: 10
+    }
+  }
+}
+```
+
+### 新增computed属性
+
+```javascript
+computed: {
+  /**
+   * 上次导入信息摘要
+   */
+  lastImportInfo() {
+    const savedTask = this.getImportTaskFromStorage();
+    if (savedTask && savedTask.totalCount) {
+      return `导入时间: ${this.parseTime(savedTask.saveTime)} | 总数: ${savedTask.totalCount}条 | 成功: ${savedTask.successCount}条 | 失败: ${savedTask.failureCount}条`;
+    }
+    return '';
+  }
+}
+```
+
+### 生命周期钩子修改
+
+```javascript
+created() {
+  this.getList();
+  this.restoreImportState(); // 新增:恢复导入状态
+},
+
+beforeDestroy() {
+  // 清理定时器
+  if (this.importPollingTimer) {
+    clearInterval(this.importPollingTimer);
+    this.importPollingTimer = null;
+  }
+}
+```
+
+### 需要新增/修改的方法
+
+| 方法名 | 类型 | 说明 |
+|--------|------|------|
+| saveImportTaskToStorage | 新增 | 保存导入状态到localStorage |
+| getImportTaskFromStorage | 新增 | 读取导入状态 |
+| clearImportTaskFromStorage | 新增 | 清除导入状态 |
+| restoreImportState | 新增 | 页面加载时恢复导入状态 |
+| getLastImportTooltip | 新增 | 获取上次导入提示信息 |
+| handleFileSuccess | 修改 | 上传成功后不弹窗,开始轮询 |
+| startImportStatusPolling | 新增 | 开始轮询导入状态 |
+| handleImportComplete | 新增 | 处理导入完成 |
+| viewImportFailures | 新增 | 查看导入失败记录 |
+| getFailureList | 新增 | 查询失败记录列表 |
+| clearImportHistory | 新增 | 清除导入历史记录 |
+
+---
+
+## UI组件修改
+
+### 1. 修改导入对话框
+
+**移除loading相关属性:**
+
+```vue
+<!-- 修改前 -->
+<el-dialog
+  :title="upload.title"
+  :visible.sync="upload.open"
+  width="400px"
+  append-to-body
+  @close="handleImportDialogClose"
+  v-loading="upload.isUploading"
+  element-loading-text="正在导入数据,请稍候..."
+  element-loading-spinner="el-icon-loading"
+  element-loading-background="rgba(0, 0, 0, 0.7)"
+>
+
+<!-- 修改后 -->
+<el-dialog
+  :title="upload.title"
+  :visible.sync="upload.open"
+  width="400px"
+  append-to-body
+  @close="handleImportDialogClose"
+>
+```
+
+**原因**: 导入改为后台异步处理,不需要在对话框中显示loading。
+
+### 2. 操作栏添加"查看导入失败记录"按钮
+
+**位置**: 导入按钮和导出按钮之后
+
+```vue
+<el-col :span="1.5" v-if="showFailureButton">
+  <el-tooltip
+    :content="getLastImportTooltip()"
+    placement="top"
+  >
+    <el-button
+      type="warning"
+      plain
+      icon="el-icon-warning"
+      size="mini"
+      @click="viewImportFailures"
+    >查看导入失败记录</el-button>
+  </el-tooltip>
+</el-col>
+```
+
+**条件显示**: `v-if="showFailureButton"` - 仅当有失败记录时显示
+
+### 3. 新增导入失败记录对话框
+
+**位置**: 导入结果对话框之后
+
+```vue
+<el-dialog
+  title="导入失败记录"
+  :visible.sync="failureDialogVisible"
+  width="1200px"
+  append-to-body
+>
+  <el-alert
+    v-if="lastImportInfo"
+    :title="lastImportInfo"
+    type="info"
+    :closable="false"
+    style="margin-bottom: 15px"
+  />
+
+  <el-table :data="failureList" v-loading="failureLoading">
+    <el-table-column label="采购事项ID" prop="purchaseId" align="center" />
+    <el-table-column label="项目名称" prop="projectName" align="center" :show-overflow-tooltip="true"/>
+    <el-table-column label="标的物名称" prop="subjectName" align="center" :show-overflow-tooltip="true"/>
+    <el-table-column label="失败原因" prop="errorMessage" align="center" min-width="200" :show-overflow-tooltip="true" />
+  </el-table>
+
+  <pagination
+    v-show="failureTotal > 0"
+    :total="failureTotal"
+    :page.sync="failureQueryParams.pageNum"
+    :limit.sync="failureQueryParams.pageSize"
+    @pagination="getFailureList"
+  />
+
+  <div slot="footer" class="dialog-footer">
+    <el-button @click="failureDialogVisible = false">关闭</el-button>
+    <el-button type="danger" plain @click="clearImportHistory">清除历史记录</el-button>
+  </div>
+</el-dialog>
+```
+
+**显示字段**:
+- 采购事项ID (purchaseId)
+- 项目名称 (projectName)
+- 标的物名称 (subjectName)
+- 失败原因 (errorMessage)
+
+---
+
+## 核心方法实现
+
+### 1. handleFileSuccess - 上传成功处理
+
+**修改说明**: 移除弹窗提示,改为通知+轮询
+
+```javascript
+handleFileSuccess(response, file, fileList) {
+  this.upload.isUploading = false;
+  this.upload.open = false;
+
+  if (response.code === 200) {
+    // 验证响应数据完整性
+    if (!response.data || !response.data.taskId) {
+      this.$modal.msgError('导入任务创建失败:缺少任务ID');
+      this.upload.isUploading = false;
+      this.upload.open = true;
+      return;
+    }
+
+    const taskId = response.data.taskId;
+
+    // 清除旧的轮询定时器
+    if (this.importPollingTimer) {
+      clearInterval(this.importPollingTimer);
+      this.importPollingTimer = null;
+    }
+
+    this.clearImportTaskFromStorage();
+
+    // 保存新任务的初始状态
+    this.saveImportTaskToStorage({
+      taskId: taskId,
+      status: 'PROCESSING',
+      timestamp: Date.now(),
+      hasFailures: false
+    });
+
+    // 重置状态
+    this.showFailureButton = false;
+    this.currentTaskId = taskId;
+
+    // 显示后台处理提示(不是弹窗,是通知)
+    this.$notify({
+      title: '导入任务已提交',
+      message: '正在后台处理中,处理完成后将通知您',
+      type: 'info',
+      duration: 3000
+    });
+
+    // 开始轮询检查状态
+    this.startImportStatusPolling(taskId);
+  } else {
+    this.$modal.msgError(response.msg);
+  }
+}
+```
+
+### 2. startImportStatusPolling - 轮询导入状态
+
+```javascript
+startImportStatusPolling(taskId) {
+  let pollCount = 0;
+  const maxPolls = 150; // 最多轮询150次(5分钟)
+
+  this.importPollingTimer = setInterval(async () => {
+    try {
+      pollCount++;
+
+      // 超时检查
+      if (pollCount > maxPolls) {
+        clearInterval(this.importPollingTimer);
+        this.$modal.msgWarning('导入任务处理超时,请联系管理员');
+        return;
+      }
+
+      const response = await getImportStatus(taskId);
+
+      if (response.data && response.data.status !== 'PROCESSING') {
+        clearInterval(this.importPollingTimer);
+        this.handleImportComplete(response.data);
+      }
+    } catch (error) {
+      clearInterval(this.importPollingTimer);
+      this.$modal.msgError('查询导入状态失败: ' + error.message);
+    }
+  }, 2000); // 每2秒轮询一次
+}
+```
+
+### 3. handleImportComplete - 处理导入完成
+
+```javascript
+handleImportComplete(statusResult) {
+  // 更新localStorage中的任务状态
+  this.saveImportTaskToStorage({
+    taskId: statusResult.taskId,
+    status: statusResult.status,
+    hasFailures: statusResult.failureCount > 0,
+    totalCount: statusResult.totalCount,
+    successCount: statusResult.successCount,
+    failureCount: statusResult.failureCount
+  });
+
+  if (statusResult.status === 'SUCCESS') {
+    // 全部成功
+    this.$notify({
+      title: '导入完成',
+      message: `全部成功!共导入${statusResult.totalCount}条数据`,
+      type: 'success',
+      duration: 5000
+    });
+    this.showFailureButton = false; // 成功时清除失败按钮显示
+    this.getList(); // 刷新列表
+  } else if (statusResult.failureCount > 0) {
+    // 部分失败
+    this.$notify({
+      title: '导入完成',
+      message: `成功${statusResult.successCount}条,失败${statusResult.failureCount}条`,
+      type: 'warning',
+      duration: 5000
+    });
+
+    // 显示查看失败记录按钮
+    this.showFailureButton = true;
+    this.currentTaskId = statusResult.taskId;
+
+    // 刷新列表
+    this.getList();
+  }
+}
+```
+
+### 4. localStorage状态管理
+
+```javascript
+/**
+ * 保存导入任务到localStorage
+ */
+saveImportTaskToStorage(taskData) {
+  try {
+    const data = {
+      ...taskData,
+      saveTime: Date.now()
+    };
+    localStorage.setItem('purchase_transaction_import_last_task', JSON.stringify(data));
+  } catch (error) {
+    console.error('保存导入任务状态失败:', error);
+  }
+},
+
+/**
+ * 从localStorage读取导入任务
+ */
+getImportTaskFromStorage() {
+  try {
+    const data = localStorage.getItem('purchase_transaction_import_last_task');
+    if (!data) return null;
+
+    const task = JSON.parse(data);
+
+    // 数据格式校验
+    if (!task || !task.taskId) {
+      this.clearImportTaskFromStorage();
+      return null;
+    }
+
+    // 时间戳校验
+    if (task.saveTime && typeof task.saveTime !== 'number') {
+      this.clearImportTaskFromStorage();
+      return null;
+    }
+
+    // 过期检查(7天)
+    const sevenDays = 7 * 24 * 60 * 60 * 1000;
+    if (Date.now() - task.saveTime > sevenDays) {
+      this.clearImportTaskFromStorage();
+      return null;
+    }
+
+    return task;
+  } catch (error) {
+    console.error('读取导入任务状态失败:', error);
+    this.clearImportTaskFromStorage();
+    return null;
+  }
+},
+
+/**
+ * 清除localStorage中的导入任务
+ */
+clearImportTaskFromStorage() {
+  try {
+    localStorage.removeItem('purchase_transaction_import_last_task');
+  } catch (error) {
+    console.error('清除导入任务状态失败:', error);
+  }
+}
+```
+
+### 5. restoreImportState - 恢复导入状态
+
+```javascript
+/**
+ * 恢复导入状态
+ * 在created()钩子中调用
+ */
+restoreImportState() {
+  const savedTask = this.getImportTaskFromStorage();
+
+  if (!savedTask) {
+    this.showFailureButton = false;
+    this.currentTaskId = null;
+    return;
+  }
+
+  // 如果有失败记录,恢复按钮显示
+  if (savedTask.hasFailures && savedTask.taskId) {
+    this.currentTaskId = savedTask.taskId;
+    this.showFailureButton = true;
+  }
+}
+```
+
+### 6. getLastImportTooltip - 获取导入提示
+
+```javascript
+/**
+ * 获取上次导入的提示信息
+ */
+getLastImportTooltip() {
+  const savedTask = this.getImportTaskFromStorage();
+  if (savedTask && savedTask.saveTime) {
+    const date = new Date(savedTask.saveTime);
+    const timeStr = this.parseTime(date, '{y}-{m}-{d} {h}:{i}');
+    return `上次导入: ${timeStr}`;
+  }
+  return '';
+}
+```
+
+### 7. viewImportFailures - 查看失败记录
+
+```javascript
+/**
+ * 查看导入失败记录
+ */
+viewImportFailures() {
+  this.failureDialogVisible = true;
+  this.getFailureList();
+}
+```
+
+### 8. getFailureList - 查询失败记录列表
+
+```javascript
+/**
+ * 查询失败记录列表
+ */
+getFailureList() {
+  this.failureLoading = true;
+  getImportFailures(
+    this.currentTaskId,
+    this.failureQueryParams.pageNum,
+    this.failureQueryParams.pageSize
+  ).then(response => {
+    this.failureList = response.rows;
+    this.failureTotal = response.total;
+    this.failureLoading = false;
+  }).catch(error => {
+    this.failureLoading = false;
+
+    // 处理不同类型的错误
+    if (error.response) {
+      const status = error.response.status;
+
+      if (status === 404) {
+        // 记录不存在或已过期
+        this.$modal.msgWarning('导入记录已过期,无法查看失败记录');
+        this.clearImportTaskFromStorage();
+        this.showFailureButton = false;
+        this.currentTaskId = null;
+        this.failureDialogVisible = false;
+      } else if (status === 500) {
+        this.$modal.msgError('服务器错误,请稍后重试');
+      } else {
+        this.$modal.msgError(`查询失败: ${error.response.data.msg || '未知错误'}`);
+      }
+    } else if (error.request) {
+      // 请求发送了但没有收到响应
+      this.$modal.msgError('网络连接失败,请检查网络');
+    } else {
+      this.$modal.msgError('查询失败记录失败: ' + error.message);
+    }
+  });
+}
+```
+
+### 9. clearImportHistory - 清除历史记录
+
+```javascript
+/**
+ * 清除导入历史记录
+ * 用户手动触发
+ */
+clearImportHistory() {
+  this.$confirm('确认清除上次导入记录?', '提示', {
+    confirmButtonText: '确定',
+    cancelButtonText: '取消',
+    type: 'warning'
+  }).then(() => {
+    this.clearImportTaskFromStorage();
+    this.showFailureButton = false;
+    this.currentTaskId = null;
+    this.failureDialogVisible = false;
+    this.$message.success('已清除');
+  }).catch(() => {});
+}
+```

+| 失败记录字段 | name, employeeId, idCard, phone, errorMessage | purchaseId, projectName, subjectName, errorMessage |
+| 轮询超时时间 | 5分钟(150次×2秒) | 5分钟(150次×2秒) |
+
+### B. 后端API依赖
+
+本设计依赖以下后端API(已实现):
+
+1. **导入数据**:
+   - 路径: `POST /ccdi/purchaseTransaction/importData`
+   - 参数: `updateSupport` (是否更新已存在数据)
+   - 响应: `{code: 200, data: {taskId: "task-xxx"}}`
+
+2. **查询导入状态**:
+   - 路径: `GET /ccdi/purchaseTransaction/importStatus/{taskId}`
+   - 响应: `{code: 200, data: {taskId, status, totalCount, successCount, failureCount}}`
+
+3. **查询导入失败记录**:
+   - 路径: `GET /ccdi/purchaseTransaction/importFailures/{taskId}`
+   - 参数: `pageNum`, `pageSize`
+   - 响应: `{code: 200, rows: [...], total: N}`
+
+### C. 技术栈
+
+- **前端框架**: Vue 2.6.12
+- **UI组件库**: Element UI 2.15.14
+- **HTTP客户端**: Axios 0.28.1
+- **状态管理**: localStorage (浏览器原生API)
+
+### D. 参考文档
+
+- 员工信息维护导入功能: `ruoyi-ui/src/views/ccdiEmployee/index.vue`
+- 采购交易API文档: `doc/api/ccdi_purchase_transaction_api.md`
