POI导出数据到Excel的多个Sheet
Apache POI是Apache软件基金会的开放源码函式库，POI提供API给Java程序对Microsoft Office格式档案读和写的功能。
一、PSGInfoSearchAction.java中设置response返回参数
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.math.BigDecimal;
import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Date;
import java.util.Iterator;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.lang.StringUtils;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
/**
* @param mapping
* @param form
* @param request
* @param response
* @return
* @throws Exception
*/
public ActionForward psgInfoView(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
response.reset();// 清空response
response.addHeader("Content-Disposition", "attachment;filename="+fileName);// 设置response的Header
response.setContentType("application/octet-stream");
PoiExportExcel.PoiWriteExcel("工作薄",psgList,request,response);
return null;
}
return mapping.findForward("psgInfo");//跳转到统计页面
}
}
二、PoiExportExcel.java组装数据与Excel导出格式
package com.sasis.util;
import java.io.BufferedOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;
import com.sasis.model.PSGInfoSearchForReport;
