我有一个代码,读取java
中的受保护的Excel,但该代码给我错误。 我的java代码。如何在java中读取密码保护的.xls文件?
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.security.GeneralSecurityException;
import java.util.Iterator;
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.crypt.Decryptor;
import org.apache.poi.poifs.crypt.EncryptionInfo;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
public class REadProtectedExcel {
public static void main(String[] args) {
String fname = "D:/Vijay/BRS_docs/10168/20.11.2014/20.11.2014/JCR_30.12.14_I Pay.xls";
try {
POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream(fname));
EncryptionInfo info = new EncryptionInfo(fs);
Decryptor d = Decryptor.getInstance(info);
if (d.verifyPassword("vijay")) {
System.out.println("Password correct");
FileInputStream fis = new FileInputStream(fname);
HSSFWorkbook workbook = new HSSFWorkbook(fis);
HSSFSheet sheet = workbook.getSheetAt(0);
Iterator rowIter = sheet.rowIterator();
while (rowIter.hasNext()) {
HSSFRow myRow = (HSSFRow) rowIter.next();
Iterator cellIter = myRow.cellIterator();
while (cellIter.hasNext()) {
String cellvalue = "";
HSSFCell myCell = (HSSFCell) cellIter.next();
if (myCell.getCellType() == HSSFCell.CELL_TYPE_STRING) {
cellvalue = myCell.getStringCellValue();
} else if (myCell.getCellType() == HSSFCell.CELL_TYPE_NUMERIC) {
cellvalue = "" + myCell.getNumericCellValue();
} else if (myCell.getCellType() == HSSFCell.CELL_TYPE_BOOLEAN) {
cellvalue = "" + myCell.getBooleanCellValue();
} else if (myCell.getCellType() == HSSFCell.CELL_TYPE_FORMULA) {
cellvalue = "" + myCell.getCellFormula();
} else if (myCell.getCellType() == HSSFCell.CELL_TYPE_BLANK) {
cellvalue = "";
}
System.out.println("cellvalue--" + cellvalue);
}
}
} else {
System.out.println("Password wrong");
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (GeneralSecurityException e) {
e.printStackTrace();
}
}
}
此代码给我下面的错误。

- 我使用poi3.9罐子,XMLBeans的-2.3.0jar,POI-ooml-3.6
- 我没有事先得到issue.Thanks。
- 或请分享阅读.xls文件的另一种方式。
你用xlsx试过了吗? xls是一个很难的要求吗? –
[密码保护的Excel文件](http://stackoverflow.com/questions/2609301/password-protected-excel-file)的可能的重复,并寻找poi – Setu
的第二个答案,第二个答案不起作用。 – vijayk
