XSSFWorkbook根据模板生成Excel文件

1、项目依赖jar包

poi-ooxml-3.9-20121203.jar

2、项目Excel模板

3、代码实现 

package com.neusoft.tax.szrs.zzszda.job;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.ArrayList;
import java.util.List;

			rowList.add(cellList);
		}

		String filePath = downloadExcel(fileName,outFileName,rowList);
    }

	        workbook.write(out);
	        out.close();
	        file.close();	      
		} catch (Exception e) {
