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）        Sheet sheet = workbook.getSheet(0);                 int rows = sheet.getRows();        int cols = sheet.getColumns();        HashMap<String,String> dataMap = new HashMap<String, String>();        for(int colNum=1;colNum<cols;++colNum){            for(int rowNum=1;rowNum<rows;++rowNum){                 //获取单元格值                String zNumStr = sheet.getCell(colNum,rowNum).getContents().trim();                //double zNum = Double.parseDouble(zNumStr);                //获取当前z值的x值                String curRowXStr = sheet.getCell(0,rowNum).getContents();                //Double curRowX = Double.parseDouble(curRowXStr);                     //获取当前z值的Y值                String curColYStr = sheet.getCell(colNum,0).getContents();               // Double curColY = Double.parseDouble(curColYStr);                String key = "("+curRowXStr+","+curColYStr+")";                dataMap.put(key, zNumStr);            }        }        return dataMap;    }    private static void printMap(HashMap<String,String> dataMap){        for (java.util.Map.Entry<String, String> en: dataMap.entrySet()) {            System.out.println(en.getKey()+"..."+en.getValue());        }    }}
