1.部分代码展示

@RequestMapping(value = "downReadilyPager")
@ResponseBody
public void downReadilyPager(HttpServletRequest request, HttpServletResponse response) {try {ReadilyRequest readilyRequest = new ReadilyRequest();List<Readily> list = new ArrayList<Readily>();String ids = request.getParameter("ids");if (!StringUtils.isBlank(ids)) {String[] idArray = ids.split(",");for (String id : idArray) {Readily temp = readilyService.get(Integer.parseInt(id));Account account = accountService.get(temp.getAccountId());temp.setAccount(account);list.add(temp);}}HSSFWorkbook hssfWorkbook = new HSSFWorkbook();SimpleDateFormat simpledate = new SimpleDateFormat("yyyy-MM-dd");HSSFSheet sheet = hssfWorkbook.createSheet("报表管理");HSSFRow row = sheet.createRow(0);HSSFCell cell = row.createCell(0);//设置表格样式sheet.setColumnWidth(0, 4000);sheet.setColumnWidth(1, 4000);sheet.setColumnWidth(2, 8000);sheet.setColumnWidth(3, 8000);sheet.setColumnWidth(4, 8000);sheet.setColumnWidth(5, 8000);sheet.setColumnWidth(6, 8000);sheet.setColumnWidth(7, 8000);sheet.setColumnWidth(8, 8000);sheet.setColumnWidth(9, 8000);sheet.setColumnWidth(10, 8000);//一定要放在循环外,只能声明一次String fileName = "报表-" + simpledate.format(new Date());cell.setCellValue(fileName);row = sheet.createRow(1);cell = row.createCell(0);cell.setCellValue("主题");cell = row.createCell(1);cell.setCellValue("内容");cell = row.createCell(2);cell.setCellValue("地址");cell = row.createCell(3);cell.setCellValue("状态");cell = row.createCell(4);cell.setCellValue("拍摄时间");cell = row.createCell(5);cell.setCellValue("处理时间");cell = row.createCell(6);cell.setCellValue("描述");cell = row.createCell(7);cell.setCellValue("昵称");cell = row.createCell(8);cell.setCellValue("电话");cell = row.createCell(9);cell.setCellValue("图片");int line = 2;//循环 开始赋值if (list != null && list.size() > 0) {for (int i = 0; i < list.size(); i++) {Readily s = list.get(i);row = sheet.createRow(line++);if (s.getTitle() != null) {cell = row.createCell(0);row.setHeight((short) (6 * 200));cell.setCellValue(s.getTitle());}if (s.getContent() != null) {cell = row.createCell(1);cell.setCellValue(s.getContent());}if (s.getAddress() != null) {cell = row.createCell(2);cell.setCellValue(s.getAddress());}if (s.getState() != null) {cell = row.createCell(3);if (s.getState() == 0) {cell.setCellValue("未处理");} else if (s.getState() == 1) {cell.setCellValue("已经处理");}}if (s.getTime() != null) {cell = row.createCell(4);cell.setCellValue(simpledate.format(s.getTime()));}if (s.getUpdateTime() != null) {cell = row.createCell(5);cell.setCellValue(simpledate.format(s.getUpdateTime()));}if (s.getRemark() != null) {cell = row.createCell(6);cell.setCellValue(s.getRemark());}if (s.getAccount().getNickName() != null) {cell = row.createCell(7);cell.setCellValue(s.getAccount().getNickName());}if (s.getAccount().getPhone() != null) {cell = row.createCell(8);cell.setCellValue(s.getAccount().getPhone());}if (!StringUtils.isBlank(s.getImgUrl())) {String[] imgUrls = s.getImgUrl().split(",");int length = imgUrls.length;HSSFPatriarch patriarch = sheet.createDrawingPatriarch();//for循环中处理图片的关键代码for (int j = 0; j < length; j++) {BufferedImage bufferImg = null;//网络图片用下面的方法处理不适合本地图片URL url = new URL(imgUrls[j]);ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();bufferImg = ImageIO.read(url);ImageIO.write(bufferImg, "jpg", byteArrayOut);

}
