读取excel文件数据，封装成hashmap

需要jxl包，程序下载：链接：http://pan.baidu.com/s/1slCIfUl 密码：gd3k

注意：jxl只能读取.xls文件，不能识别.xlsx。

package test;

import java.io.File;
import java.security.KeyStore.Entry;
import java.util.HashMap;

import jxl.Sheet;
import jxl.Workbook;
public class ReadExcelToMap {

    public static void main(String[] args) throws Exception {

        //通过Workbook的静态方法getWorkbook选取Excel文件
        String relativePath = System.getProperty("user.dir");
        String path=relativePath+"\\file\\12.xls";
        Workbook workbook = Workbook.getWorkbook(new File(path));
        HashMap<String,String> dataMap = getDataMap(workbook);
        workbook.close();
        printMap(dataMap);
    }
    /**
     * 根据excel得到map数据
     * @param workbook
     * @return
     */
    private static  HashMap<String,String> getDataMap(Workbook workbook) {
        //通过Workbook的getSheet方法选择第一个工作簿（从0开始）

        int rows = sheet.getRows();
        int cols = sheet.getColumns();

        for(int colNum=1;colNum<cols;++colNum){
            for(int rowNum=1;rowNum<rows;++rowNum){
