java 读取修改xlsx java读取xlsx文件

从一个给定的.xlsx文件,我试图使用Java读取数据.

我读取文件的代码如下：

public static void main(String[] args) throws Exception {
FileInputStream file = new FileInputStream(new File("E:\\test1.xlsx"));
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet test = workbook.getSheetAt(0);
student emp = new student();
Iterator itr = test.iterator();
itr.next();
while(itr.hasNext()){
Row row = itr.next();
emp.reedData(row);
System.out.println(id+","+name+","+options);
}

方法如下：

void reedData(Row row){
id= row.getCell(0).toString();
name= row.getCell(1).toString();
options= row.getCell(2).toString();
}

但是,我得到这样的输出：

1.0,X,play game
,,sing song
2.0,Y,play game
,,sing song

而不是上面,我希望输出看起来像这样：

1.0,X,{play game,sing song}
2.0,Y,{play game,sing song}

该问题是因为我正在合并.xlsx文件中的两个单元格.

有什么建议吗？

先感谢您..

解决方法:

这就是我做的.

import static java.lang.System.out;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.ArrayList;
import java.util.Iterator;
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
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.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.DataFormatter;
import org.apache.poi.ss.usermodel.IndexedColors;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class read {
public static void main(String [] args){
FileInputStream excelFile = new FileInputStream(new File(keep));
XSSFWorkbook wb = new XSSFWorkbook(excelFile);
XSSFSheet sheet = wb.getSheetAt(0);
int rowCount; // number of rows of newly form excel files
rowCount= sheet.getPhysicalNumberOfRows();
out.println(rowCount);
//trying to iterate the excel file
int i =0;
Iterator rowIterator = sheet.iterator();
do{
Row row = rowIterator.next();
Iterator cellIterator = row.cellIterator();
while(cellIterator.hasNext()) {
Cell cell = cellIterator.next();
if(cell.getColumnIndex()==0) { // to read the first column
DataFormatter df = new DataFormatter();
String str2 = df.formatCellValue(cell);
customerNo.add(str2);
}
}
++i;
if(i>rowCount)break;
//break;
}while(rowIterator.hasNext());
wb.close();
}
}

希望这可以帮助.
