想不想像写jsp一样的去定义一个excel模板，然后再像用jstl和el表达式那样往excel模板里面传入变量，现在用jxls全部可以轻松搞定了，核心代码非常简单。

    //调用引擎生成excel报表
    XLSTransformer transformer = new XLSTransformer();
    Workbook workbook = transformer.transformMultipleSheetsList(is, objects, listSheetNames, "list", new HashMap(), 0);
    workbook.write(new FileOutputStream("c:\\xlsExportUtils.xls"));

下面来看看excel模板是怎么定义的。

是不是和jsp里面的jstl很像。

下面是这个测试例子的完整代码：

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import net.sf.jxls.exception.ParsePropertyException;
import net.sf.jxls.transformer.XLSTransformer;

import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.ss.usermodel.Workbook;

/**

public class XlsExportUtil {

  public static void createExcel() throws ParsePropertyException, InvalidFormatException, IOException {}

  @SuppressWarnings("rawtypes")
  public static void main(String[] args) throws ParsePropertyException, InvalidFormatException, IOException {
    //获取Excel模板文件
    String fileDir = XlsExportUtil.class.getResource("").getFile();
    String filePath = fileDir + "XlsExportUtilTemplate.xls";
    System.out.println("excel template file:" + filePath);
    FileInputStream is = new FileInputStream(filePath);

    //创建测试数据
    Map<String, Object> map = new HashMap<String, Object>();
    List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
    Map<String, Object> map1 = new HashMap<String, Object>();
    map1.put("name", "电视");
    map1.put("price", "3000");
    map1.put("desc", "3D电视机");
    map1.put("备注", "中文测试");
    Map<String, Object> map2 = new HashMap<String, Object>();
    map2.put("name", "空调");
    map2.put("price", "2000");
    map2.put("desc", "变频空调");
    map1.put("备注", "测试中文");
    list.add(map1);
    list.add(map2);
    map.put("list", list);

    ArrayList<List> objects = new ArrayList<List>();
    objects.add(list);
    objects.add(list);
    objects.add(list);
    objects.add(list);

    //sheet的名称
    List<String> listSheetNames = new ArrayList<String>();
    listSheetNames.add("1");
    listSheetNames.add("2");
    listSheetNames.add("3");
    listSheetNames.add("4");

    //调用引擎生成excel报表
    XLSTransformer transformer = new XLSTransformer();
    Workbook workbook = transformer.transformMultipleSheetsList(is, objects, listSheetNames, "list", new HashMap(), 0);
    workbook.write(new FileOutputStream("c:\\xlsExportUtils.xls"));

  }
}
