解決方法
寫excel時使用 SXSSFWorkbook workbook = new SXSSFWorkbook(xssfWorkbook , 1000);只在內存中留1000行，不會占用過多的內存。下面只貼了部分代碼。
public static void createExcelByTrade(List<String[]> mergeCellConfigList , Map<String, String[]> cellConfMap , List dataList ,String tempPath , String fileName ) { try { int excelRowNum = 0; short fontSize = 12; // 創建新的Excel 工作簿 XSSFWorkbook xssfWorkbook = new XSSFWorkbook(); SXSSFWorkbook workbook = new SXSSFWorkbook(xssfWorkbook , 1000); Sheet sheet = workbook.createSheet(fileName); // 設置合並表頭 setMergeHeaderCellByTrade( workbook, sheet, mergeCellConfigList , excelRowNum, fontSize ); excelRowNum ++ ; excelRowNum ++ ; //設置表頭 setHeaderCell( workbook, sheet, cellConfMap , excelRowNum, fontSize ); excelRowNum ++ ; //查詢數據庫中所有的數據 setCellData( workbook, sheet, cellConfMap, dataList, excelRowNum, fontSize); // 新建一輸出文件流 FileOutputStream fOut = new FileOutputStream(tempPath); // 把相應的Excel 工作簿存盤 workbook.write(fOut); //清空緩沖區數據 fOut.flush(); // 操作結束，關閉文件 fOut.close(); System.out.println("文件生成..."); } catch (Exception e) { e.printStackTrace(); System.out.println("已運行 xlCreate() : " + e); } }
