Java读取以xls和csv为后缀名的EXCEL

1,Java读取xls为后缀名的EXCEL

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.servlet.http.HttpServletRequest;

public class UplpolicyNo {

@SuppressWarnings("unchecked")
 public static void readExcelFile(String fileName) {
  // 获取工作区
  Workbook workbook = null;
  try {
   workbook = Workbook.getWorkbook(new File(fileName));
  } catch (Exception e1) {
  }
  // 通过Workbook的getSheet方法选择第一个工作簿（从0开始）
  Sheet sheet = workbook.getSheet(0);
  System.out.println("---------工作簿==" + sheet.getRows());
  String qunarPolicyno = "";
  for (int i = 0, n = sheet.getRows(); i < n; i++)
  {
   int j = 0;
   Cell c1 = sheet.getCell(j++, i);
   String policyno1 = c1.getContents();
  
   Cell c2 = sheet.getCell(j++, i);
   String policyno2 = c2.getContents();
  
   Cell c3 = sheet.getCell(j++, i);
   String policyno3 = c3.getContents();
  
   Cell c4 = sheet.getCell(j++, i);
   String policyno4 = c4.getContents();
  
   Cell c5 = sheet.getCell(j++, i);
   String policyno5 = c5.getContents();
  
   if (policyno1.equals("") && policyno2.equals("") &&
    policyno3.equals("") && policyno4.equals("") && policyno5.equals("")) {
    String errorInfo = "上传(Excel)第" + (i - 9) + "行终止！";
    System.out.println(errorInfo);
    break;
   }
  }
  workbook.close();
 }

2,Java读取以csv为后缀名的EXCEL

import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
