2003 的限制 + - `ExcelUtil.java:1682` - 使用 SXSSFWorkbook 进行流式写入，但内存优化有限 + - `ExcelUtil.java:325-525` - `importExcel` 方法一次性加载整个 Sheet 到内存，无法处理大文件 + - POI 的 DOM 解析模式导致大文件内存占用过高 + +2. **业务需求**： + - 需要支持导入导出超过 10 万行数据 + - 需要支持单元格内容超过 32767 字符（POI STRING 类型限制） + - 需要降低内存占用，避免 OOM + +3. **EasyExcel 优势**： + - 基于 SAX 解析，真正的流式读写 + - 内存占用仅与行数据大小相关，与文件大小无关 + - API 设计简洁，注解驱动 + - 官方维护活跃，社区成熟 + +## Proposed Solution + +### 技术方案 + +1. **保持 API 兼容性**： + - 保留 `@Excel` 和 `@Excels` 注解接口 + - 保留 `ExcelUtil` 的公共方法签名 + - 保留 `ExcelHandlerAdapter` 接口（适配 EasyExcel 的写处理器） + +2. **核心实现变更**： + - 使用 `EasyExcel.write()` 替代 POI 的 Workbook/Sheet 操作 + - 使用 `EasyExcel.read()` 替代 POI 的 Workbook 解析 + - 实现自定义的 `HeadGenerator` 和 `ContentStyleStrategy` 以支持样式 + +3. **依赖变更**： + - 移除 `poi-ooxml` 依赖 + - 添加
