在Java中使用POI框架讀取xlsm文件時出錯

Question

我無法使用POI框架（HSSF）讀取xlsm文件。閱讀xlsm文件時出現以下錯誤。

提供的數據似乎在Office 2007+ XML中。您正在調用處理OLE2 Office文檔的POI部分。你需要調用POI的不同部分來處理這些數據（例如XSSF而不是HSSF）

我試着通過XSSF來讀取文件。即使這樣也不能解決問題。任何人都可以告訴我如何使用poi框架在Java代碼中讀取xlsm文件，並向該文件寫入新的工作表。

Answer 1

看來你正在使用apache-poi。

我用下面的代碼來閱讀我的XLSM文件

FileInputStream fileIn=new FileInputStream("d:\\excelfiles\\WeeklyStatusReport.xlsm"); 

Workbook wb=WorkbookFactory.create(fileIn);  //this reads the file 

final Sheet sheet=wb.getSheet("Sheet_name"); //this gets the existing sheet in xlsmfile 
//use wb.createSheet("sheet_name"); to create a new sheet and write into it 

然後你可以使用行和單元格類閱讀的內容，

最後寫做

FileOutputStream fileOut=new FileOutputStream("d:\\excelfiles\\WeeklyStatusReport.xlsm"); 
wb.write(fileOut); 

Answer 2

第一下載這些JAR並將它們添加到構建路徑中：

• XMLBeans的-2.3.0.jar
• POI-OOXML-架構 - 3.7.jar
• POI-OOXML-3.9.jar
• POI-3.9.jar
• 的dom4j-1.6.1.jar

現在你可以試試這段代碼。它會讀取XLSX和XLSM文件：

import java.io.File; 
import java.util.Iterator; 
import org.apache.poi.ss.usermodel.Cell; 
import org.apache.poi.ss.usermodel.Row; 
import org.apache.poi.ss.usermodel.WorkbookFactory; 

public class ReadMacroExcel { 
public static void main(String[] args) { 
try { 
    //Create a file from the xlsx/xls file 
      File f=new File("F:\\project realated file\\micro.xlsm"); 

      //Create Workbook instance holding reference to .xlsx file 
      org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(f); 
      System.out.println(workbook); 

    //printing number of sheet avilable in workbook 
    int numberOfSheets = workbook.getNumberOfSheets(); 
    System.out.println(numberOfSheets); 
    org.apache.poi.ss.usermodel.Sheet sheet=null; 
    //Get the sheet in the xlsx file 
    for (int i = 0; i < numberOfSheets; i++) { 


     sheet = workbook.getSheetAt(i); 
    System.out.println(sheet.getSheetName()); 

    //Iterate through each rows one by one 
    Iterator<Row> rowIterator = sheet.iterator(); 
    while (rowIterator.hasNext()) 
    { 
     Row row = rowIterator.next(); 
     //For each row, iterate through all the columns 
     Iterator<Cell> cellIterator = row.cellIterator(); 

     while (cellIterator.hasNext()) 
     { 
      Cell cell = cellIterator.next(); 
      //Check the cell type and format accordingly 
      switch (cell.getCellType()) 
      { 
       case Cell.CELL_TYPE_NUMERIC: 
        System.out.print(cell.getNumericCellValue() + "t"); 
        break; 
       case Cell.CELL_TYPE_STRING: 
        System.out.print(cell.getStringCellValue() + "t"); 
        break; 
      } 
     } 
     System.out.println(""); 
    } 
} 
} 
catch (Exception e) 
{ 
    e.printStackTrace(); 
} 


    } 
}
