由于上述所有答案都没有用，所以这是工作代码：
只需编写一个填充必要字段的主方法并使用transform（）。

答案 3 :(得分：2)
在我看来，你应该使用'SS Usermodel'。有关该主题的更多信息，请参阅Apache POI的网站。
答案 4 :(得分：2)
请参阅文章Upgrading to POI 3.5, including converting existing HSSF Usermodel code to SS Usermodel (for XSSF and HSSF)。有一个例子here。

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）
