本文实例讲述了jsp导出excel并支持分sheet导出的方法。分享给大家供大家参考，具体如下：

public DownloadFile exportToExcel() throws Exception{ String config_value = systemConfigService.getConfigValueByKey("Export.Xls"); logger.info("获取的导出类型为execl表格"+",每页sheet导出的行数为:"+config_value+"行-------------------"); File file = new File(new SimpleDateFormat("yyyy-MM-dd").format(new Date())+".xls"); WritableWorkbook wbook = null ; WritableSheet wsheet =null; wbook = Workbook.createWorkbook(file); //建立excel文件 long startTime = System.currentTimeMillis(); try { ExportToExcelSearchCondition condittion = ((ExportToExcelSearchCondition) ServletContext.currentSession().getAttribute("condittion")); List<ContentToExcel> cte = new ArrayList<ContentToExcel>(); if(condittion == null){ throw new Exception("session获取查询条件失败"); }else{ //根据条件查询需要导出的数据 cte = category2ContentDAO.searchByCondition(condittion.getCategoryId(), condittion.getHSDFlag(), condittion.getExternalContentId(),condittion.getContentName(),condittion.getContentId(), condittion.getSystemId(), condittion.getState(), condittion.getCpId(),condittion.getContentType(),condittion.getBeforemodifyTime(),condittion.getAftermodifyTime()); } logger.info("开始导出excel表格--"); if(StringUtils.isNotBlank(config_value)){ int value = NumberUtils.toInt(config_value); if( cte !=null && cte.size()>0 ){ int k = 0;//分sheet的个数 int i = 0;//用于循环Excel的行号 Iterator<ContentToExcel> it = cte.iterator(); Map<String,String> contentidAndContentTypeMap = new HashMap<String,String>(); Map<String,String> contentIdAndDurationMap= new HashMap<String,String>(); for (ContentToExcel contentToExcel : cte) { contentidAndContentTypeMap.put(contentToExcel.getContentId(), contentToExcel.getContentType()); } //计算时长 contentIdAndDurationMap = category2ContentDAO.getDurationByContentIdMap(contentidAndContentTypeMap); /** * 1)采用iterator迭代器进行迭代，与for循环相比可优化迭代效率。 * 2)大量数据影响效率，求大数据量的解决办法。 * add by guohua.yuan 2013-06-08 */ while(it.hasNext()){ ContentToExcel contentToExcel = it.next(); if( i % value == 0){ wsheet = wbook.createSheet("节目单导出("+(int)(i/value+1)+")", (int)(i/value+1)); //工作表名称 //设置Excel字体 WritableFont wfont = new WritableFont(WritableFont.ARIAL, 10, WritableFont.BOLD, false, jxl.format.UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLACK);

希望本文所述对大家jsp程序设计有所帮助。
