我首先給出一個Excele數據的讀入的方式（使用的是jxl.jar包）
package com.ccniit.readexcel;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.IOException;import java.io.InputStream;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import jxl.Sheet;import jxl.Workbook;import jxl.read.biff.BiffException;
public class ExcelHander {
public static String[] getColName(String desc) {
InputStream is = null; String[] colNames = null; try { is = new FileInputStream(new File(desc)); Workbook wb = Workbook.getWorkbook(is); Sheet sheet = wb.getSheet(0); int cols = sheet.getColumns(); colNames = new String[cols]; for (int i = 0; i < cols; i++) { colNames[i] = sheet.getCell(i, 0).getContents(); // System.out.println("列名： " + colNames[i]);
} is.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (BiffException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return colNames; } public List<Map<String, Object>> readExcel(String desc) { List<Map<String, Object>> datas = null; try { InputStream is = new FileInputStream(new File(desc)); Workbook wb = Workbook.getWorkbook(is); if(wb == null){ return null; } Sheet sheet = wb.getSheet(0); int cols = sheet.getColumns(); int rows = sheet.getRows(); datas = new ArrayList<Map<String, Object>>(); for (int i = 1; i < rows; i++) { Map<String, Object> data = new HashMap<String, Object>(); for (int j = 0; j < cols; j++) { String key = sheet.getCell(j, 0).getContents(); // System.out.println("key:" + key); Object value = (Object) sheet.getCell(j, i).getContents(); // System.out.println("value:" + value.toString()); data.put(key, value); } datas.add(data); } is.close(); wb.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (BiffException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return datas; }
}
