开源jxls - java导Excel(多sheet) - 模板文件定义类似jsp的el表达式

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"));

}
