如何使用Java 8和Apache POI库保存符合xlsx文件的符号?
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("Sheet 1");
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("\uD83D\uDD25\uD83D\uDD25");
try {
FileOutputStream outputStream = new FileOutputStream("text.xlsx");
workbook.write(outputStream);
workbook.close();
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
结果,我得到一个带符号“????”的文件而不是“”。
