└── tsconfig.json

2. 核心服务类实现

// BulkOrderProcessor.ts - 批量订单处理核心类
import { pool } from '@evershop/evershop/src/lib/postgres/connection';
import { getOrdersBaseQuery } from '@evershop/evershop/src/modules/oms/services/getOrdersBaseQuery';
import { OrderCollection } from '@evershop/evershop/src/modules/oms/services/OrderCollection';
import { changeOrderStatus } from '@evershop/evershop/src/modules/oms/services/updateOrderStatus';
import { getConnection, startTransaction, commit, rollback } from '@evershop/postgres-query-builder';

export class BulkOrderProcessor {
  private orderIds: number[];
  private operationType: string;
  private newStatus: string;

  constructor(orderIds: number[], operationType: string, newStatus?: string) {
    this.orderIds = orderIds;
    this.operationType = operationType;
    this.newStatus = newStatus || '';
  }

  // 批量更新订单状态
  async bulkUpdateStatus(): Promise<{ success: number; failed: number }> {
    let successCount = 0;
    let failedCount = 0;
    const connection = await getConnection(pool);

    try {
      await startTransaction(connection);

      for (const orderId of this.orderIds) {
        try {
          await changeOrderStatus(orderId, this.newStatus, connection);
          successCount++;
        } catch (error) {
          console.error(`Failed to update order ${orderId}:`, error);
          failedCount++;
        }
      }

      await commit(connection);
      return { success: successCount, failed: failedCount };
    } catch (error) {
      await rollback(connection);
      throw new Error(`Bulk update failed: ${error.message}`);
    }
  }

  // 批量查询订单
  async getOrdersByFilters(filters: any[]): Promise<any[]> {
    const baseQuery = getOrdersBaseQuery();
    const orderCollection = new OrderCollection(baseQuery);
    
    await orderCollection.init(filters);
    return await orderCollection.items();
  }

  // 验证状态流转合法性
  validateStatusTransition(currentStatus: string, targetStatus: string): boolean {
    const statusFlow = this.getStatusFlow();
    const currentIndex = statusFlow.indexOf(currentStatus);
    const targetIndex = statusFlow.indexOf(targetStatus);
    
    return targetIndex >= currentIndex;
  }

  private getStatusFlow(): string[] {
    // 获取系统配置的状态流转顺序
    return ['pending', 'processing', 'shipped', 'delivered', 'cancelled'];
  }
}

3. API接口实现

// bulkUpdateStatus.ts - 批量状态更新API
import { Request, Response } from 'express';
import { BulkOrderProcessor } from '../../services/BulkOrderProcessor';

export default async function bulkUpdateStatus(req: Request, res: Response) {
  try {
    const { orderIds, newStatus } = req.body;

    if (!orderIds || !Array.isArray(orderIds) || orderIds.length === 0) {
      return res.status(400).json({
        error: 'Order IDs are required and must be a non-empty array'
      });
    }

    if (!newStatus) {
      return res.status(400).json({
        error: 'New status is required'
      });
    }

    const processor = new BulkOrderProcessor(orderIds, 'status_update', newStatus);
    const result = await processor.bulkUpdateStatus();

    res.json({
      success: true,
      message: `Bulk update completed`,
      result: {
        total: orderIds.length,
        success: result.success,
        failed: result.failed
      }
    });
  } catch (error) {
    console.error('Bulk update error:', error);
    res.status(500).json({
      error: 'Internal server error during bulk update'
    });
  }
}

4. 路由配置

// route.json
{
  "methods": ["POST"],
  "path": "/bulk/orders/status",
  "access": "admin"
}

5. 数据验证Schema

// payloadSchema.json
{
  "type": "object",
  "properties": {
    "orderIds": {
      "type": "array",
      "items": {
        "type": "integer"
      },
      "minItems": 1
    },
    "newStatus": {
      "type": "string",
      "enum": ["pending", "processing", "shipped", "delivered", "cancelled"]
    }
  },
  "required": ["orderIds", "newStatus"],
  "additionalProperties": false
}

高级功能实现

批量发货处理

// 批量发货服务
class BulkShipmentService {
  async processBulkShipment(orderIds: number[], carrier: string, trackingNumbers: string[]) {
    const connection = await getConnection(pool);
    
    try {
      await startTransaction(connection);
      
      for (let i = 0; i < orderIds.length; i++) {
        const orderId = orderIds[i];
        const trackingNumber = trackingNumbers[i] || this.generateTrackingNumber();
        
        await this.createShipment(orderId, carrier, trackingNumber, connection);
        await changeOrderStatus(orderId, 'shipped', connection);
      }
      
      await commit(connection);
    } catch (error) {
      await rollback(connection);
      throw error;
    }
  }
  
  private generateTrackingNumber(): string {
    return `TRK${Date.now()}${Math.random().toString(36).substr(2, 9)}`;
  }
}

数据导出功能

// OrderExporter.ts - 订单数据导出
import { createObjectCsvStringifier } from 'csv-writer';
import { getOrdersBaseQuery } from '@evershop/evershop/src/modules/oms/services/getOrdersBaseQuery';
import { OrderCollection } from '@evershop/evershop/src/modules/oms/services/OrderCollection';

export class OrderExporter {
  async exportToCSV(filters: any[]): Promise<string> {
    const orders = await this.getOrdersByFilters(filters);
    
    const csvStringifier = createObjectCsvStringifier({
      header: [
        { id: 'order_id', title: '订单ID' },
        { id: 'order_number', title: '订单编号' },
        { id: 'customer_name', title: '客户姓名' },
        { id: 'grand_total', title: '订单总额' },
        { id: 'status', title: '订单状态' },
        { id: 'created_at', title: '创建时间' }
      ]
    });
    
    const header = csvStringifier.getHeaderString();
    const records = csvStringifier.stringifyRecords(orders);
    
    return header + records;
  }
}

前端界面集成

React组件实现

// BulkOperationsPanel.jsx
import React, { useState } from 'react';
import { useQuery, useMutation } from '@apollo/client';
import { Button, Select, Message, DataTable } from 'components';

const BulkOperationsPanel = () => {
  const [selectedOrders, setSelectedOrders] = useState([]);
  const [selectedAction, setSelectedAction] = useState('');
  
  const [bulkUpdate] = useMutation(BULK_UPDATE_MUTATION);
  
  const handleBulkUpdate = async () => {
    try {
      const result = await bulkUpdate({
        variables: {
          orderIds: selectedOrders,
          status: selectedAction
        }
      });
      
      Message.success(`成功更新 ${result.data.bulkUpdate.success} 个订单`);
    } catch (error) {
      Message.error('批量更新失败');
    }
  };
  
  return (
    <div className="bulk-operations-panel">
      <h3>批量订单操作</h3>
      <div className="action-bar">
        <Select
          value={selectedAction}
          onChange={setSelectedAction}
          options={[
            { value: 'processing', label: '标记为处理中' },
            { value: 'shipped', label: '标记为已发货' },
            { value: 'cancelled', label: '取消订单' }
          ]}
        />
        <Button 
          onClick={handleBulkUpdate}
          disabled={!selectedOrders.length || !selectedAction}
        >
          执行批量操作
        </Button>
      </div>
    </div>
  );
};

性能优化策略

数据库操作优化

// 使用批量插入优化性能
async function bulkInsertOrderEvents(orderIds: number[], eventData: any) {
  const values = orderIds.map(orderId => [
    orderId,
    eventData.type,
    JSON.stringify(eventData.data),
    new Date()
  ]);
  
  await pool.query(`
    INSERT INTO order_events (order_id, event_type, event_data, created_at)
    VALUES ${values.map((_, index) => 
      `($${index * 4 + 1}, $${index * 4 + 2}, $${index * 4 + 3}, $${index * 4 + 4})`
    ).join(', ')}
  `, values.flat());
}

内存管理优化

// 流式处理大数据量导出
async function* streamOrders(filters: any[]) {
  const batchSize = 1000;
  let offset = 0;
  
  while (true) {
    const orders = await this.getOrdersBatch(filters, offset, batchSize);
    if (orders.length === 0) break;
    
    yield orders;
    offset += batchSize;
  }
}

安全考虑

权限验证

// 操作权限验证中间件
export const requireBulkOperationPermission = (req: Request, res: Response, next: NextFunction) => {
  const user = req.currentUser;
  
  if (!user || !user.permissions.includes('bulk_order_operations')) {
    return res.status(403).json({
      error: 'Insufficient permissions for bulk operations'
    });
  }
  
  // 验证操作数量限制
  const { orderIds } = req.body;
  if (orderIds.length > 1000 && !user.permissions.includes('unlimited_bulk_operations')) {
    return res.status(403).json({
      error: 'Exceeded maximum bulk operation limit'
    });
  }
  
  next();
};

部署与测试

单元测试示例

// BulkOrderProcessor.test.ts
import { BulkOrderProcessor } from './BulkOrderProcessor';
import { pool } from '@evershop/evershop/src/lib/postgres/connection';

describe('BulkOrderProcessor', () => {
  let processor: BulkOrderProcessor;
  
  beforeEach(() => {
    processor = new BulkOrderProcessor([1, 2, 3], 'status_update', 'processing');
  });
  
  it('should validate status transitions correctly', () => {
    expect(processor.validateStatusTransition('pending', 'processing')).toBe(true);
    expect(processor.validateStatusTransition('shipped', 'pending')).toBe(false);
  });
  
  it('should handle bulk update with mixed results', async () => {
    // Mock database operations
    jest.spyOn(pool, 'query').mockImplementation(async () => {
      // Simulate partial success
      throw new Error('Some orders failed');
    });
    
    const result = await processor.bulkUpdateStatus();
    expect(result.success).toBeGreaterThan(0);
    expect(result.failed).toBeGreaterThan(0);
  });
});
