Question

我正在尝试读取xlsx文件，但我收到错误“工作簿无法解析类型”。如何解决？

InputStream input = new BufferedInputStream(
                        new FileInputStream("F://myFile.xlsx"));
            POIFSFileSystem fs = new POIFSFileSystem( input );
            Workbook wb1 = WorkbookFactory.create(new File(fs)); // error is here
            HSSFSheet sheet = wb.getSheetAt(0);


            Iterator rows = sheet.rowIterator();
            while( rows.hasNext() ) {  
                HSSFRow row = (HSSFRow) rows.next();
                System.out.println("\n");
                Iterator cells = row.cellIterator();

Answer 1

Java无法直接读取Excel文件。您需要第三方库来完成此任务。从给定的代码看，您需要添加Apache POI中的库，特别是POI-HSSF and POI-XSSF。

Answer 2

首先，您需要在类路径中包含所有适当的Apache POI component jars and their dependencies。其次，您需要导入POI类。

一旦下载了Apache POI并添加了components to your classpath，您的代码就会如下所示：

import org.apache.poi.ss.usermodel.*;

public class POIExample {
   public static void main(String[] args) {
        File f = new File("F://myFile.xlsx"));
        Workbook wb1 = WorkbookFactory.create(f);
        Sheet sheet = wb.getSheetAt(0);

        for (Row row : sheet) {
            System.out.println("\n");
            for (Cell cell : row) {
               System.out.println("Found Cell");
            }
        }
    }
}
