我想使用apache poi从excel读取数据并将该数据存储到2Dimentional String Array中。使用下面的代码,我将显示数据,但我想存储数据。
public static void main(String[] args) throws Exception {
File f = new File("C:/Users/SYKAMREDDY/Desktop/testData.xls");
FileInputStream fis = new FileInputStream(f);
HSSFWorkbook wb = new HSSFWorkbook(fis);
HSSFSheet sh = wb.getSheet("Data");
int rc=sh.getLastRowNum()-sh.getFirstRowNum();
for (int i = 1; i < rc; i++) {
Row r = sh.getRow(i);
for (int j = 1; j < r.getLastCellNum(); j++) {
String s = r.getCell(j).getStringCellValue();
System.out.print(s+" ");
}
System.out.println();
}
}
答案 0 :(得分:0)
尝试使用byteArray
简化示例:
4555784
另外,请查看How can I convert POI HSSFWorkbook to bytes?
如果你想使用字符串,那么简单
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try {
workbook.write(bos);
} finally {
bos.close();
}
byte[] bytes = bos.toByteArray();
