[英]Accessing Excel Sheets in Java using Apache POI with Eclipse IDE
[英]Getting error while accessing excel data using apache POI and java
我有一个函数,它接受 Excel 路径和工作表名称并返回行数的 int 值,但是当我尝试运行它时,它给出了以下错误。 我是 Java 新手,所以可能是因为我太愚蠢了哈哈。
我的系统:
我的输入:
代码:
package com.test.system;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFCellStyle;
import org.apache.poi.xssf.usermodel.XSSFColor;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class NewClass {
private static FileInputStream fis;
private static FileOutputStream fileOut;
private static XSSFWorkbook wb;
private static XSSFSheet sh;
private static XSSFCell cell;
private static XSSFRow row;
private static XSSFCellStyle cellstyle;
private static XSSFColor mycolor;
public static int setExcelFile(String ExcelPath,String SheetName) throws Exception
{
int noOfRows = -1;
try{
File f = new File(ExcelPath);
if(!f.exists()){
System.out.println("File doesn't exist.");
}
else{
fis=new FileInputStream(ExcelPath);
System.out.println(fis);
wb=new XSSFWorkbook(fis);
sh = wb.getSheet(SheetName);
//sh = wb.getSheetAt(0); //0 - index of 1st sheet
if (sh == null)
{
sh = wb.createSheet(SheetName);
}
}
noOfRows = sh.getLastRowNum();
}catch (IOException e){System.out.println(e.getMessage());}
return (noOfRows);
}
}
错误:

我尝试了一切,但仍然没有成功。
在 else 语句中你应该写
fis=new FileInputStream(f);
代替
fis=new FileInputStream(ExcelPath);
并且您不能使用: System.out.println(fis); //它不会工作
