理解SXSSFWorkbook. SXSSFWorkbook是Apache POI库的一部分，它是XSSFWorkbook的扩展版本，专门设计用于处理大型数据集。相比于XSSFWorkbook，SXSSFWorkbook通过将数据写入临时文件而不是保存在内存中来节省内存，因此可以处理更大的数据集。 2.XSSFWorkbook、HSSFWorkbook . 또한, 기존 코드에서도 다행히 SXSSFWorkbook을 사용했는데 SXSSFWorkbook은 다른 workbook과 달리 streaming api를 사용하기 때문에 대용량 데이터 다운로드에 용이합니다. 해결 코드. 원인에서도 이미 언급했지만 아래의 두 가지 코드를 적용하면 해결이 됩니다. 1.SXSSFWorkbook defaults to using inline strings instead of a shared strings table. This is very efficient, since no document content needs to be kept in memory, but is also known to produce documents that are incompatible with some clients. With shared strings enabled all unique strings in the document has to be kept in memory. JavaのPOIでSXSSFWorkbookを使ってOutOfMemoryを回避する方法です。30列で15000行を出力しようとしたところ、11000行を出力した辺りでOutOfMemoryとなりました。調べたところXSSFWorkbookではなくSXSSFWorkbookを使うと処理が軽くなり、メモリ使用量が抑えられるとのこと。ここではJavaのPOIでSXSSFWorkbookを .Since 3.8-beta3, POI provides a low-memory footprint SXSSF API built on top of XSSF. SXSSF is an API-compatible streaming extension of XSSF to be used when very large spreadsheets have to be produced, and heap space is limited.
Please consult: similar question SXSSFWorkBook is write only, it doesn't support reading. For low memory reading of .xlsx files, you should look at the XSSF and SAX EventModel documentation: Gagravarr. If memory wouldn't be an issue you could use a XSSFSheet instead e.g. 你一定没用过最简单的使用SXSSFWorkbook快速导出百万条数据 发表于 2020-04-29 本文字数： 4.3k 热度 ℃ 常见的导出可能上百万甚至千万的数据量业务场景 是SXSSFWorkbook的子类,在构建SXSSFWorkbook对象的时候可以配置是否压缩磁盘中的excel.压缩后磁盘的空间使用率会大大减少,但是队导出的性能就有所影响. 重点说下SXSSFWorkbook的相关操作. 官方介绍翻译后大致如下: SXSSFの場合は SXSSFWorkbook を使います。 ではその違いは、XSSFに対し SXSSFはメモリ抑えめの出力 を行うとのことです。 もしXSSFで大量のデータを出力した際に、 OutOfMemoryエラーが発生 する場合があるとのことです。（実際はこのエラーの発生は確認していませ .SXSSFWorkbook (POI API Documentation) Packages. org.apache.poi; org.apache.poi.common; org.apache.poi.common.usermodel; org.apache.poi.common.usermodel.fonts; org.apache.poi.ddf; org.apache.poi.extractor 在之前我们知道处理xls的excel用的workbook是HSSFWorkbook，处理xlsx的excel用的是XSSFWorkbook。 上面两个类导出excel的时候数据会驻留在内存中，所以当数据量大的时候容易造成内存溢出。SXSSFWorkbook是用来生成海量excel数据文件,主要原理是サンプル(POI 4 より前のバージョン) package test; import java.io.FileOutputStream; import org.apache.poi.ss.usermodel.Cell; import org.apache.poi.ss .
