EasyPoi導出問題

導出代碼如下：
Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams(), PriceExcelModel.class, priceExcelModelList);
File file = FileUtil.createFile(PROCEED_DATA_SOURCE_PATH);
workbook.write(new FileOutputStream(file));
workbook.close();

 當數據量超過65536時，導出結果為多個sheet，會產生不方便閱讀的問題。

如果設置最大sheet行，代碼如下：

ExportParams exportParams = new ExportParams();
        exportParams.setMaxNum(200000);
        exportParams.setType(ExcelType.HSSF);
        Workbook workbook = ExcelExportUtil.exportExcel(exportParams, PriceExcelModel.class, priceExcelModelList);
        File file = FileUtil.createFile(PROCEED_DATA_SOURCE_PATH);
        workbook.write(new FileOutputStream(file));
        workbook.close();

會產生如下報錯，如下代碼報錯：

ERROR 17:00:02 [org.jeecgframework.poi.excel.export.base.ExportBase:213] Invalid row number (65536) outside allowable range (0..65535)
java.lang.IllegalArgumentException: Invalid row number (65536) outside allowable range (0..65535)
	at org.apache.poi.hssf.usermodel.HSSFRow.setRowNum(HSSFRow.java:252)
	at org.apache.poi.hssf.usermodel.HSSFRow.<init>(HSSFRow.java:86)
	at org.apache.poi.hssf.usermodel.HSSFRow.<init>(HSSFRow.java:70)

 錯誤源為：

public void setRowNum(int rowIndex) {
        int maxrow = SpreadsheetVersion.EXCEL97.getLastRowIndex();
        if (rowIndex >= 0 && rowIndex <= maxrow) {
            this.rowNum = rowIndex;
            if (this.row != null) {
                this.row.setRowNumber(rowIndex);
            }

        } else {
            throw new IllegalArgumentException("Invalid row number (" + rowIndex + ") outside allowable range (0.." + maxrow + ")");
        }
}

 后來明白了，HSSF最大sheet導出行為65536行，超出后會自動分為多個sheet。

需要導出大量數據到同一個sheet的話，可以通過配置導出類型，代碼如下：

ExportParams exportParams = new ExportParams();
exportParams.setType(ExcelType.XSSF);

這樣就可以成功導出了。
