Question

我正在使用ubuntu 14版本的java 1.7版本在STS中运行我的代码，我无法解决问题，即使我已经测试了以下2个程序，只需添加Apache poi 3.9版本的所有jar和版本3.2 for第二次。但每次它都给出几乎相同的错误请建议我一些事情提前谢谢。

以下是我从.xlsx文件

中读取数据的代码

import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class ReadData {

    public static void main(String a[]) throws FileNotFoundException {

        try {
            File file = new File("Test.xlsx");
            FileInputStream fis = new FileInputStream(file);
            XSSFWorkbook hwb = new XSSFWorkbook(fis);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }
}

我得到的错误是

Exception in thread "main" org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException: Package should contain a content type part [M1.13] at org.apache.poi.util.PackageHelper.open(PackageHelper.java:39) at org.apache.poi.xssf.usermodel.XSSFWorkbook.<init>(XSSFWorkbook.java:273) at com.axxera.selenium.ReadData.main(ReadData.java:18) Caused by: org.apache.poi.openxml4j.exceptions.InvalidFormatException: Package should contain a content type part [M1.13] at org.apache.poi.openxml4j.opc.ZipPackage.getPartsImpl(ZipPackage.java:201) at org.apache.poi.openxml4j.opc.OPCPackage.getParts(OPCPackage.java:684) at org.apache.poi.openxml4j.opc.OPCPackage.open(OPCPackage.java:275) at org.apache.poi.util.PackageHelper.open(PackageHelper.java:37)

以下代码用于从.xls文件

中读取数据

public class ReadData {

    public static void main(String a[]) throws FileNotFoundException {

        try {
            File file = new File("Test.xls");
            FileInputStream fis = new FileInputStream(file);
            HSSFWorkbook hwb = new HSSFWorkbook(fis);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }
}

及以上代码正在生成此错误

Exception in thread "main" org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF) at org.apache.poi.poifs.storage.HeaderBlock.<init>(HeaderBlock.java:128) at org.apache.poi.poifs.storage.HeaderBlock.<init>(HeaderBlock.java:112) at org.apache.poi.poifs.filesystem.NPOIFSFileSystem.<init>(NPOIFSFileSystem.java:300) at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init>(HSSFWorkbook.java:400) at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init>(HSSFWorkbook.java:381) at com.axxera.selenium.ReadData.main(ReadData.java:17)

Answer 1

好像您在xls下保存了xlsx，反之亦然。

试试Workbook wb = WorkbookFactory.create(file | inputStream)。它打开独立于文件扩展名的文件。

Answer 2

您的代码与poi-3.5-FINAL.jar和.xls文件

一起正常运行

Answer 3

您可以使用.xls确定代码。但是您应该处理另一个文件扩展名（.xlsx）

使用Java和Apache poi从.xls或.xlsx文件中读取内容
