java poi 提取txt文件内容添加到excel

Posted 2023-03-09

我提取txt文档中的数据，怎么在提取所有数据时添加条件提取个别的关键字并且输出到另一个excel文件中（这个文件是已存在的并且是以插入的方式输入的）我的代码怎么不成立呢？ 请各位大神帮帮忙吧 ！
我的代码如下：

public void readTxtYsx()//读文件
try
String encoding="GBK";//// 字符编码(可解决中文乱码问题 )
File file=new File("D:\\CRM-BOSS-BASS-EC.txt.txt");//句柄
if(file.isFile() && file.exists()) //判断文件是否存在
InputStreamReader read = new InputStreamReader(
new FileInputStream(file),encoding);//考虑到编码格式
BufferedReader bufferedReader = new BufferedReader(read);
String lineTxt=null;
while((lineTxt = bufferedReader.readLine()) != null)

WriteYSX(row++,lineTxt.toString().trim());

ofs = new FileOutputStream(filePath);
wb.write(ofs);
ofs.flush();
read.close();

else
System.out.println("找不到指定的文件");

catch (Exception e)
System.out.println("读取文件内容出错");
e.printStackTrace();


public void WriteYSX( int a ,String str) throws IOException //写如EXCEL

String arr[] = str.split("#%#");
sheet = wb.getSheetAt(0);
HSSFRow hssfrow = null ;
HSSFCell celldate=null;
hssfrow = sheet.createRow(a);
for (int i = 0; i < arr.length; i++)

celldate = hssfrow.createCell(i);
celldate.setCellValue(arr[i]);

HSSFRow row=sheet.getRow(a);
celldate=row.getCell(2);
//System.out.println(celldate.getStringCellValue());
if(celldate.getStringCellValue().equals("市场经营部"))

sheet = wb.getSheetAt(1);
row=sheet.getRow(a);
// //遍历第一行所有的列(单元格)
for(int j=0;j<arr.length;j++)

Cell cell = row.getCell(j); //获取第一个单元格
//在这我怎么把我想要取的一行中有“市场经营字段的”这个行添加到我的另一个已存在的excel中呢。？
System.out.println(cell.getRichStringCellValue().getString());


System.out.println("iii----"+celldate.getStringCellValue()+"++++++++++++++"+"行"+a);

参考技术A 帮你在网上找了以下几个文章，可以解决你的问题，请参考。

如果满意，请采纳。 参考技术B 你这里有什么具体的问题？

row=sheet.getRow(a);

这一部，我觉得可能会有问题，如果你这个行不存在的话，可能得到的是一个NULL对象，
因为现在你在是插入数据。所以要创建行。 参考技术C 这是部分代码。

Excel中的行，不应该是和TXT文件的行完全对应的。
EXCEL 空的时候，可能是相应的；非空时，就不同了。 参考技术D 建议你用PageOffice，能帮你解决这个问题。很专业的。
