# 员工采购交易信息管理功能实施计划

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**目标:** 构建完整的员工采购交易信息管理模块，支持CRUD操作、分页查询、异步导入导出、批量删除等功能

**架构:** 基于若依框架前后端分离架构，后端使用MyBatis Plus + EasyExcel + Redis实现异步导入，前端使用Vue 2 + Element UI

**技术栈:**
- 后端: Spring Boot 3.5.8, MyBatis Plus 3.5.10, EasyExcel, Redis
- 前端: Vue 2.6.12, Element UI 2.15.14, Axios
- 数据库: MySQL 8.2.0

## 实施注意事项

1. **必填字段**: purchaseId, purchaseCategory, subjectName, purchaseQty, budgetAmount, purchaseMethod, applyDate, applicantId, applicantName, applyDepartment
2. **异步导入**: 使用@Async + @Transactional + Redis
3. **批量操作**: 每批500条记录
4. **更新策略**: 先批量删除，再批量插入
5. **数据验证**: Jakarta Validation + 自定义业务验证
6. **审计字段**: 使用@TableField(fill = FieldFill.INSERT/INSERT_UPDATE)
7. **错误处理**: 只返回失败记录，不返回成功记录
8. **导入轮询**: 每2秒轮询一次状态
