Apache POI,同时使用 XSSF 和 HSSF

发布于 2024-10-04 08:26:17 字数 282 浏览 4 评论 0原文

我对 Apache POI 项目有疑问。

我无法在“相同的 Java 类” 中使用 XSSFHSSF。我应该下载哪个 jar 或应该将哪个工件添加到 Maven 中?

我想同时处理 xlsxlsx 文件。当我收到 Excel 版本错误时,我会将XSSF 更改为 HSSFHSSF 更改为 XSSF

我该怎么做?

I have a problem with Apache POI project.

I failed to use XSSF and HSSF in the "Same Java Class". Which jar should I download or which artifact should I get add into maven?

I want to handle both xls and xlsx files at the same time. When I get excel version error, I will change the XSSF to HSSF or HSSF to XSSF.

How can I do this?

与其这样做,不如尝试使用新版本的 Apache POI 3.7,它具有 SS 包,可以处理 HSSF 和 XSSF,而不必担心

此处的类型详细信息:http://poi.apache.org/spreadsheet/index.html

Instead of doing that, try using the new release of Apache POI 3.7, it has SS package which handles both HSSF and XSSF without worrying about type

除了“标准”SS 包解决方案之外,您还可以简单地使用 if 语句 将正确的工作簿格式正确加载到工作簿界面对象,就像这样:

Workbook workbook; //<-Interface, accepts both HSSF and XSSF.
File file = new File("YourExcelFile.xlsx");
if (FileUtils.getFileExt(file).equalsIgnoreCase("xls")) {
  workbook = new HSSFWorkbook(new FileInputStream(file));
} else if (FileUtils.getFileExt(file).equalsIgnoreCase("xlsx")) {
  workbook = new XSSFWorkbook(new FileInputStream(file));
} else {
  throw new IllegalArgumentException("Received file does not have a standard excel extension.");
}

Aside from the "standard" SS package solution, you can also simply use an if statement to correctly load the right workbook format into an Workbook interface object, like so:

Workbook workbook; //<-Interface, accepts both HSSF and XSSF.
File file = new File("YourExcelFile.xlsx");
if (FileUtils.getFileExt(file).equalsIgnoreCase("xls")) {
  workbook = new HSSFWorkbook(new FileInputStream(file));
} else if (FileUtils.getFileExt(file).equalsIgnoreCase("xlsx")) {
  workbook = new XSSFWorkbook(new FileInputStream(file));
} else {
  throw new IllegalArgumentException("Received file does not have a standard excel extension.");
}

使用同时处理 xssf 和 hssf 的工厂

import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;

Workbook wb = WorkbookFactory.create(new File("file"))

Use the factory instead which handles both xssf and hssf

import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;

Workbook wb = WorkbookFactory.create(new File("file"))

这对我有用:

    filePath = "C:\Users\user1\workspace\myproject\Excel.xlsx"
    String extension = FilenameUtils.getExtension(filePath);
    System.out.println(extension);

This worked for me:

    filePath = "C:\Users\user1\workspace\myproject\Excel.xlsx"
    String extension = FilenameUtils.getExtension(filePath);
    System.out.println(extension);
