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.io.File;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.servlet.http.HttpServletRequest;
import org.w3c.dom.*
import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
/**
* <p>Description: Java读取xls为后缀名的EXCEL</p>
* @author
* @version 1.0
*/
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.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import jxl.Sheet;
import jxl.Workbook;
/**
* <p>Description: Java读取以csv为后缀名的EXCEL</p>
* @author
* @version 1.0
*/
public class QunarHaihangBillCompareUpUtil {

public static void CSVAnalysis(String fileName,HttpServletRequest request)
{
InputStreamReader fr = null;
BufferedReader br = null;
int k = 0;
try {
fr = new InputStreamReader(new FileInputStream(fileName));
br = new BufferedReader(fr);
String rec = null;
String[] argsArr = null;
String orderNum = "";
String period = "";
while ((rec = br.readLine()) != null)
{
++k;
if(k != 1)
{
argsArr = rec.split(",");
orderNum = argsArr[0];
period = argsArr[1];
}
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (fr != null)
fr.close();
if (br != null)
br.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
