EasyPoi的几个入口工具类 | |||||
什么场景该用哪个方法 | |||||
--------------------------- | --------------------------- | ||||
1.ExcelExportUtil Excel导出( | |||||
普通导出,模板导出) | |||||
2.ExcelImportUtil Excel导入 | |||||
3.WordExportUtil Word导出(只支持docx ,doc版本poi存在图片的bug,暂不支持) | |||||
- 导出 | |||||
1.正规excel导出 (格式简单,数据量可以,5W以内吧) | |||||
注解方式: ExcelExportUtil.exportExcel(ExportParams entity, Class<?> pojoClass,Collection<?> dataSet) | |||||
2.不定多少列,但是格式依然简单数据库不大 | |||||
自定义方式: ExcelExportUtil.exportExcel(ExportParams entity, List<ExcelExportEntity> entityList,Collection<?> dataSet) | |||||
3.数据量大超过5W,还在100W以内 | |||||
注解方式 ExcelExportUtil.exportBigExcel(ExportParams entity, Class<?> pojoClass,IExcelExportServer server, Object queryParams) | |||||
自定义方式: ExcelExportUtil.exportBigExcel(ExportParams entity, List<ExcelExportEntity> excelParams,IExcelExportServer server, Object queryParams) | |||||
4.样式复杂,数据量尽量别大 | |||||
模板导出 ExcelExportUtil.exportExcel(TemplateExportParams params, Map<String, Object> map) | |||||
5.一次导出多个风格不一致的sheet | |||||
模板导出 ExcelExportUtil.exportExcel(Map<Integer, Map<String, Object>> map,TemplateExportParams params) | |||||
6.一个模板但是要导出非常多份 | |||||
模板导出 ExcelExportUtil.exportExcelClone(Map<Integer, List<Map<String, Object>>> map,TemplateExportParams params) | |||||
7.模板无法满足你的自定义,试试html | |||||
自己构造html,然后我给你转成excel ExcelXorHtmlUtil.htmlToExcel(String html, ExcelType type) | |||||
8.数据量过百万级了.放弃excel吧,csv导出 | |||||
注解方式: CsvExportUtil.exportCsv(CsvExportParams params, Class<?> pojoClass, OutputStream outputStream) | |||||
自定义方式: CsvExportUtil.exportCsv(CsvExportParams params, List<ExcelExportEntity> entityList, OutputStream outputStream) | |||||

10.PDF导出 | |||||
模板导出: TODO | |||||
- 导入 | |||||
如果想提高性能 ImportParams 的concurrentTask 可以帮助并发导入,仅单行,最小1000 | |||||
excel有单个的那种特殊读取,readSingleCell 参数可以支持 | |||||
1. 不需要检验,数据量不大(5W以内) | |||||
注解或者MAP: ExcelImportUtil.importExcel(File file, Class<?> pojoClass, ImportParams params) | |||||
2. 需要导入,数据量不大 | |||||
注解或者MAP: ExcelImportUtil.importExcelMore(InputStream inputstream, Class<?> pojoClass, ImportParams params) | |||||
3. 数据量大了,或者你有特别多的导入操作,内存比较少,仅支持单行 | |||||
SAX方式 ExcelImportUtil.importExcelBySax(InputStream inputstream, Class<?> pojoClass, ImportParams params, IReadHandler handler) | |||||
4. 数据量超过EXCEL限制,CSV读取 | |||||
小数据量: CsvImportUtil.importCsv(InputStream inputstream, Class<?> pojoClass,CsvImportParams params) | |||||
