只需编写一个填充必要字段的主方法并使用transform()。

答案 7 :(得分:0)

我已经实现了一些代码来复制工作簿,无论它们是什么类型:它使用接口,因此您可以使用HSSFWorkbook,XSSFWorkbook和SXSSFWorkbook。

这将复制带有图片,字体,样式和行的工作表: 对于我的用例,我需要在现有模板中插入新行并写入SXSSFWorkbook,所以我不直接复制所有工作表和行,而是选择要复制的工作表,然后复制其中的部分我想要。

    Workbook template = getTemplateSource(...);
    Workbook wb = new SXSSFWorkbook(...);
    ExcelTemplate builder = new ExcelTemplate(template);

    int sheetIndex = ...;
    Sheet srcSheet = template.getSheetAt(sheetIndex);
    Sheet dstSheet = ExcelTemplate.copySheet(template, wb, sheetIndex);
    int rowNumber = getDataInsertionRow();
    int foot = rowNumber + 1;
    builder.copyRows(wb, srcSheet, dstSheet, 0, rowNumber, 0);
    for (....) {
        writeNewRows(dstSheet, rowNumber++, data);
    }
    builder.copyRows(wb, srcSheet, dstSheet, foot, srcSheet.getLastRowNum() + 1, rowNumber);

这是代码(我试图删除所有测试,但也许我忘记了一些未使用的行)
