excel文件：example.xls

文件內(nèi)容大概是下面這樣的：

現(xiàn)在要讀取excel的內(nèi)容寫入數(shù)據(jù)庫中

String filepath = "example.xls";String fileType = filepath.substring(filepath.lastIndexOf(".") + 1, filepath.length());InputStream is = null;Workbook wb = null;try {is = new FileInputStream(filepath);if (fileType.equals("xls")) {wb = new HSSFWorkbook(is);} else if (fileType.equals("xlsx")) {wb = new XSSFWorkbook(is);} else {throw new Exception("讀取的不是excel文件");}Sheet sheet = wb.getSheetAt(0);List<Map<String, String>> sheetList = new ArrayList<Map<String, String>>();List<String> titles = new ArrayList<String>();int rowSize = sheet.getLastRowNum() + 1;for (int j = 0; j < rowSize; j++) {Row row = sheet.getRow(j);if (row == null) {continue;}int cellSize = row.getLastCellNum();if (j == 0) {for (int k = 0; k < cellSize; k++) {Cell cell = row.getCell(k);titles.add(cell.toString());}} else {Map<String, String> rowMap = new HashMap<String, String>();for (int k = 1; k < titles.size(); k++) {Cell cell = row.getCell(k);String key = titles.get(k);String value = null;if (cell != null) {value = cell.toString();}rowMap.put(key, value);}sheetList.add(rowMap);//rowMap.clear();}}wb.close();is.close();titles.clear();String keyword;String cityid;String showtype;String cateid;String cityname;for (Map<String, String> params : sheetList) {keyword = params.get("查詢詞");cityid = params.get("cityid");showtype = params.get("showtype");cateid = params.get("cateid");cityname = cityService.getCityNameByCityId(Integer.parseInt(cityid));correctTopQueryService.insertRecode(keyword, cityid, cityname, showtype, cateid);}} catch (Exception e) {e.printStackTrace();}
