解决方法
写excel时使用 SXSSFWorkbook workbook = new SXSSFWorkbook(xssfWorkbook , 1000);只在内存中留1000行，不会占用过多的内存。下面只贴了部分代码。
public static void createExcelByTrade(List<String[]> mergeCellConfigList , Map<String, String[]> cellConfMap , List dataList ,String tempPath , String fileName ) { try { int excelRowNum = 0; short fontSize = 12; // 创建新的Excel 工作簿 XSSFWorkbook xssfWorkbook = new XSSFWorkbook(); SXSSFWorkbook workbook = new SXSSFWorkbook(xssfWorkbook , 1000); Sheet sheet = workbook.createSheet(fileName); // 设置合并表头 setMergeHeaderCellByTrade( workbook, sheet, mergeCellConfigList , excelRowNum, fontSize ); excelRowNum ++ ; excelRowNum ++ ; //设置表头 setHeaderCell( workbook, sheet, cellConfMap , excelRowNum, fontSize ); excelRowNum ++ ; //查询数据库中所有的数据 setCellData( workbook, sheet, cellConfMap, dataList, excelRowNum, fontSize); // 新建一输出文件流 FileOutputStream fOut = new FileOutputStream(tempPath); // 把相应的Excel 工作簿存盘 workbook.write(fOut); //清空缓冲区数据 fOut.flush(); // 操作结束，关闭文件 fOut.close(); System.out.println("文件生成..."); } catch (Exception e) { e.printStackTrace(); System.out.println("已运行 xlCreate() : " + e); } }
