SXSSFWorkbook 转 InputStream「建议收藏」

大家好，又见面了，我是你们的朋友全栈君。

public static InputStream workbookConvertorStream(SXSSFWorkbook workbook) {
    InputStream in = null;
        //临时缓冲区
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        //创建临时文件
        workbook.write(out);
        byte [] bookByteAry = out.toByteArray();
        in = new ByteArrayInputStream(bookByteAry);
