POI匯出資料到Excel的多個Sheet
阿新 • • 發佈：2019-01-24
Apache POI是Apache軟體基金會的開放原始碼函式庫，POI提供API給Java程式對Microsoft Office格式檔案讀和寫的功能。
一、PSGInfoSearchAction.java中設定response返回引數
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);// 設定response的Header response.setContentType("application/octet-stream"); PoiExportExcel.PoiWriteExcel("工作薄",psgList,request,response); return null; } return mapping.findForward("psgInfo");//跳轉到統計頁面 } }
二、PoiExportExcel.java組裝資料與Excel匯出格式
三、匯出的Excel檔案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.HSSFCell; import org.apache.poi.hssf.usermodel.HSSFCellStyle;
