使用jxl，poi读取excel文件

作用：在java后台添加一个方法，读取导入的excel内容，根据需要返回相应的sql语句，以完成对临时表的插入操作。

使用jxl读取excel文件

package com.sixthf.bi.sapp.util;

import java.io.IOException;
import java.io.InputStream;

import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;

import org.apache.struts.upload.FormFile;

import com.got.util.uid.UUIDGener;

public class PhoneUtil{

    /**
     * 读取xls文件内容
     *
     * @param file 想要读取的文件对象,importfilesn;
     * @return  sql语句
     */
public static String readPhoneExcel(FormFile formFile,String importfilesn) throws IOException, BiffException  {
    　　InputStream stream = formFile.getInputStream();
        Workbook rwb = Workbook.getWorkbook(stream);
        Sheet[] sheets = rwb.getSheets();
        StringBuffer SBbuffer = new StringBuffer(); 

         for(int i=0;i<sheets.length;i++) {
            Sheet rs = rwb.getSheet(i);
            String period = rs.getCell(0, 1).getContents().replace("年", "-").replace("月", "");//得到当前工作表的第二行第一列即账务周期
            for(int j=1;j<rs.getRows();j++) {
                String first = rs.getCell(0, j).getContents();
                String phone = rs.getCell(1, j).getContents();//得到当前工作表的当前行的第二列即接入号码
                if(!first.contains("合计")) {
                    if(!phone.equals("") && !phone.equals("小计:")) {
                        SBbuffer
                        .append("insert into CMMU_PAPERANSWER_TMP (SUBIMPORTFILESN,Importfilesn,answer1,answer2, answer5)values(")
                        .append("'")
                        .append(UUIDGener.getUUID().replaceAll("-", ""))
                        .append("','")
                        .append(importfilesn)
                        .append("','")
                        .append(period)
                        .append("','")
                        .append(phone)
                        .append("','");

                        for(int k=j+1;k<rs.getRows(); k++) {
                        phone = rs.getCell(1, k).getContents();
                            if(phone.contains("小计")) {
                                String costnum = rs.getCell(3, k).getContents();//得到当前工作表的当前行的第四列即费用

                                SBbuffer
                                .append(costnum)
                                .append("');")
                                .append("\n");
                                j = k;
                                break;
                            }
                            else continue;
                        }
                    }
                else continue;
                }
                else break;
            }
        }
        String string = SBbuffer.toString();
        return string;
    } 

   }

     * @return  sql语句
     */
public static String readPhoneExcel(FormFile formFile,String importfilesn) throws IOException, BiffException  {
    　  InputStream stream = formFile.getInputStream();
        HSSFWorkbook rwb = new HSSFWorkbook(stream);
        int numSheet = rwb.getNumberOfSheets();
        StringBuffer SBbuffer = new StringBuffer(); 

         for(int i=0;i<numSheet;i++) {
            HSSFSheet rs = rwb.getSheetAt(i);
            String period = rs.getRow(1).getCell((short)0).toString().replace("年", "-").replace("月", "");
            for(int j=1;j<rs.getPhysicalNumberOfRows();j++) {

                                SBbuffer
                                .append(costnum)

                                .append("\n");
                                j = k;
                                System.out.println(k);
                                break;
